Description

 The invention relates to universal woodworking machines and can be used for longitudinal sawing, turning, milling, etc. in the forestry and woodworking industries, in the field of production of building materials.

 Known universal machines for woodworking and longitudinal sawing, including a movable carriage mounted on the frame with a cutting body and end clamping elements. At the same time, when feeding logs to the working area of the machine and dredging the product, it is necessary to use additional lifting equipment - crane beams, hoists, and manipulators. However, even the presence of these additional funds does not allow the center to be fixed in the clamping elements precisely in the center, which leads to an overspending of the material, transferring part of the material from the chips or wood chips.

 A known machine for the longitudinal sawing of logs, which contains the front and rear headstock with pins for the end clamp of the logs mounted on the frame, the carriage with cutting organs, also movably mounted on the frame.

 The front and rear headstock are equipped with crankshafts with clamping elements fixed at their free ends. The log is clamped by moving the tailstock along the guides.

 The structural elements of the machine do not provide the ability to load logs and the issuance of blanks, which requires the use of special equipment - a crane, crosshead, catchers, etc., which dramatically increase the processing cycle of one log and thereby reduce the productivity of the machine.

 In addition, such equipment does not allow you to accurately center the log, which leads to overuse of material during processing.

 The aim of the invention is to accelerate the processing of one log, simplifying maintenance of the machine.

 The goal is achieved in that the machine, comprising a front headstock with a clamping element mounted on a bed along its longitudinal axis, a carriage with a cutting tool and a tailstock with a pin for interacting with the end of the log, at least mounted on the carriage along the longitudinal axis of the machine two jacks for the workpiece, and the tailstock tailstock is fixed with the possibility of lateral movement.

 In addition, a console is mounted on the tailstock on which the quill is mounted, while the axis of rotation of the console is perpendicular to the longitudinal axis of the machine.

 In addition, each jack is mounted on the carriage by means of a C-shaped bracket mounted for lateral movement.

 In addition, a V-shaped roller connected to the rotation drive is mounted on the tailstock.

 These differences allow you to place the log in the processing zone without additional lifting means, placing it on the jacks of the carriage, center its ends relative to the clamps of the headstock by these jacks, rotate the log for processing, removing the jacks, remove the product through the free zone formed after moving the console with the end clamp back grandmas.

 The tailstock drive roller helps feed the logs to the jacks and retrieve the finished product.

 In FIG. 1 shows a general view of the machine; in FIG. 2 is a section AA in FIG. one; in FIG. 3 - front headstock, section; in FIG. 4 - tailstock; in FIG. 5 - kinematic diagram of the carriage; in FIG. 6 is a view of a carriage with saw blades and a product profile; in FIG. 7 is a view B in FIG. 6; in FIG. 8 is a view of a carriage with various tools; in FIG. 9 - examples of finished products obtained on the machine.

 The machine tool contains a massive bed 1 with longitudinally covered guides 2, a front headstock rigidly fixed to the bed, a carriage and a tail head movably mounted on the bed.

 The front headstock includes a rotary clamping element 4 mounted with the possibility of rotation in the headstock housing 3 with protrusions 5 for interacting with the end of the log, a clutch for turning the element 4 on and off, connected with the rotation drive 6.

 The carriage includes mounted on the frame 7 covering guides 8, interacting with the guides of the frame, saw heads 9 with cutting replaceable bodies 10, mounted with the possibility of lateral movement and vertical movement. In FIG. 2 and 5 show an example of the mechanism of this movement.

 Brackets 11 are mounted on the frame 7, on which jacks 12 are fixed for interaction with the log. The brackets are mounted with the possibility of lateral movement to withdraw the jacks from the inner working space of the carriage and ensure its unhindered movement along the bed using the mechanism of this movement.

 The tailstock includes a housing 13 with female guides interacting with the guides of the bed, a console 14 rotatably mounted on the axis 15, a latch 16 for this rotation, a pin 17 with a flywheel 18 and protrusions 19 for interacting with the end of the log, a V-shaped roller 20 with spikes, fixed with the possibility of rotation, the steering wheel 21 associated with this roller for forced rotation. Any other, for example, electric, can be used as a rotation drive.

 The machine operates as follows.

 To process the logs, before feeding it, the console 14 is unlocked, turn it together with the pinole 17 to the side, freeing the longitudinal passage into the working area of the machine. The log is fed along the roller table (not shown) or in another way to the roller 20, rotating which the steering wheel 21, hook the log with protrusions and feed it into the working area of the machine. The carriage is brought close to the tailstock and the log is pushed with the roller 20, ensuring that it rests with the middle part on the jack farthest from the tailstock. Then, rotating another jack, hang the log in the carriage, lifting it above the roller 20. Moving the carriage along the bed, they rest the end of the log into the protrusions 5 of the element 4 of the front headstock, return the pin to the working position, turning the console, fix it and feed the tailstock to the stop ledges 19 pinoli 17 in the other end of the log.

 In this case, if necessary, jacks are used to combine the imaginary axis of the log with the longitudinal axis of the clamping element and the quill.

 After clamping the logs, the jacks are lowered, the staples are removed from the working area of the carriage and the logs are processed by setting the necessary tools on the saw heads.

 The forms and types of processing of the logs are shown in FIG. 6 - 9.
