Description

Technical Field

[0001] This utility model relates to the technical field of general lathe tools, specifically a hydraulic tailstock for a general lathe. Background Technology

[0002] "Ordinary lathe" is short for "ordinary lathe". An ordinary lathe is a horizontal lathe that can perform multiple processes on various types of workpieces such as shafts, discs, and rings. Because ordinary lathes can produce mold parts with high precision, they are not only highly accurate but also fast. Therefore, ordinary lathes are the most widely used type of lathe. Lathe machining requires the tailstock and spindle to lift the parts and clamp and limit their movement.

[0003] Common hydraulic tailstocks for ordinary rolling stock also have some problems. For example, when using a hydraulic tailstock for an ordinary rolling stock, it is necessary to move the center to limit and fix the parts. However, the stability of the center movement is poor, and it is inconvenient to replace the center according to the needs, which can easily affect the use.

[0004] Therefore, we propose a hydraulic tailstock for conventional vehicles to improve upon the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic tailstock for ordinary vehicles to solve the problems mentioned in the background art, such as poor stability of the top moving and inconvenience in replacing the top as needed, which easily affects the use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic tailstock for a general-purpose vehicle, comprising a tailstock body, a controller disposed on the left side of the front end of the tailstock body, a support plate fixedly connected to the top of the interior of the tailstock body, a connecting plate fixedly connected to the middle position of the top of the support plate, a hydraulic cylinder mounted on the right side of the connecting plate, an mounting plate mounted on the left side of the hydraulic cylinder, limit sliders fixedly connected to the upper and lower ends of the mounting plate, limit grooves respectively formed on the left side of the top of the support plate and the left side of the top of the interior of the tailstock body, a fixing plate fixedly connected to the left side of the mounting plate, an mounting block disposed on the left side of the fixing plate, a threaded groove formed on the left side of the interior of the mounting block, a threaded block disposed inside the threaded groove, and a top block fixedly connected to the left side of the threaded block.

[0007] As a further technical solution of this utility model, the limiting slider is disposed inside the limiting groove, and the limiting slider slides left and right inside the limiting groove.

[0008] As a further technical solution of this utility model, the threaded block has external threads machined on its exterior, and the threaded groove has internal threads machined on its interior, and the threaded block and the threaded groove are connected by threads.

[0009] As a further technical solution of this utility model, springs are fixedly connected at the four corners between the fixing plate and the mounting block, and dampers are provided inside the springs. A placement plate is fixedly connected at the middle position on the left side of the fixing plate, and a pressure sensor is installed inside the placement plate.

[0010] As a further technical solution of this utility model, the placement plate and pressure sensor are arranged on the right side of the mounting block, and the damper is installed between the mounting block and the fixing plate.

[0011] As a further technical solution of this utility model, a connecting seat is fixedly connected to the top of the tail frame body, and a base is provided at the bottom of the connecting seat. Mounting grooves are opened on the left and right sides inside the connecting seat and the base. Mounting bolts are provided inside the mounting grooves, and washers are provided at the top of the mounting bolts.

[0012] As a further technical solution of this utility model, the washer is disposed on the left and right sides of the top of the connecting seat, and the connecting seat is fixed by the mounting groove and the mounting bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the hydraulic tailstock of the general-purpose vehicle not only improves stability and facilitates the replacement of the top, and prevents excessive clamping, but also facilitates the fixation of the tailstock body;

[0014] By setting up a limiting slide groove, a limiting slider, a mounting plate, a threaded block, and a threaded groove, when a part needs to be clamped, the hydraulic cylinder is activated. The hydraulic cylinder drives the mounting plate to move so that the top block abuts against one side of the part to clamp and limit the part. When the mounting plate drives the top block to move, the limiting sliders at the upper and lower ends of the mounting plate will slide inside the limiting slide groove. The limiting slide groove can limit the mounting plate through the limiting slider to improve the stability of the top block's movement. When the top block needs to be replaced, the top block is rotated. The top block drives the threaded block to rotate inside the threaded groove so that the threaded block is unscrewed from inside the threaded groove. After unscrewing, the top block can be easily replaced.

[0015] By incorporating a mounting plate, pressure sensor, spring, and damper, the mounting block compresses the spring when the top block clamps the part. When the compression reaches a certain position, the mounting block contacts the pressure sensor and compresses it. When the pressure sensor is subjected to pressure, it stops the top block from moving, preventing excessive movement of the top block from damaging the part. The damper inside the spring can limit the spring and prevent the spring from causing the mounting block to shake excessively.

[0016] The tailstock body is equipped with a connecting seat, washer, mounting bolt, and mounting groove. The connecting seat at the bottom of the tailstock body is placed on the top of the tailstock body. When placing it, the mounting groove is aligned. After alignment, the mounting bolt is screwed into the inside of the mounting groove to limit and fix the connecting seat, so that the tailstock body can be installed in the appropriate position. The washer can prevent the mounting bolt from loosening. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a hydraulic tailstock for a general-purpose vehicle, comprising a tailstock body 1, a controller 2 disposed on the left side of the front end of the tailstock body 1, a support plate 3 fixedly connected to the top end inside the tailstock body 1, a connecting plate 9 fixedly connected to the middle position of the top end of the support plate 3, a hydraulic cylinder 10 mounted on the right side of the connecting plate 9, an mounting plate 8 mounted on the left side of the hydraulic cylinder 10, limit sliders 7 fixedly connected to the upper and lower ends of the mounting plate 8, limit grooves 4 respectively opened on the left side of the top end of the support plate 3 and the left side of the top end inside the tailstock body 1, a fixing plate 6 fixedly connected to the left side of the mounting plate 8, an mounting block 19 disposed on the left side of the fixing plate 6, a threaded groove 16 opened on the left side inside the mounting block 19, a threaded block 15 disposed inside the threaded groove 16, and a top block 5 fixedly connected to the left side of the threaded block 15.

[0024] The limiting slider 7 is set inside the limiting groove 4. The limiting slider 7 slides left and right inside the limiting groove 4. The threaded block 15 has external threads on its outside and internal threads on its inside. The threaded block 15 and the threaded groove 16 are connected by threads.

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when it is necessary to clamp parts, the hydraulic cylinder 10 is activated. The hydraulic cylinder 10 drives the mounting plate 8 to move so that the top block 5 abuts against one side of the part to clamp and limit the part. When the mounting plate 8 drives the top block 5 to move, the limiting sliders 7 at the upper and lower ends of the mounting plate 8 will slide inside the limiting groove 4. The limiting groove 4 can limit the mounting plate 8 through the limiting sliders 7 to improve the stability of the movement of the top block 5. When it is necessary to replace the top block 5, rotate the top block 5. The top block 5 drives the threaded block 15 to rotate inside the threaded groove 16 so that the threaded block 15 is unscrewed from the inside of the threaded groove 16. After unscrewing, the top block 5 can be easily replaced.

[0026] Springs 17 are fixedly connected at the four corners between the fixed plate 6 and the mounting block 19. A damper 18 is installed inside the spring 17. A placement plate 13 is fixedly connected at the middle position on the left side of the fixed plate 6. A pressure sensor 14 is installed inside the placement plate 13. The placement plate 13 and the pressure sensor 14 are located on the right side of the mounting block 19. The damper 18 is installed between the mounting block 19 and the fixed plate 6.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when the top block 5 clamps the part, the mounting block 19 will squeeze the spring 17. When squeezed to a certain position, the mounting block 19 will contact the pressure sensor 14 and squeeze the pressure sensor 14. When the pressure sensor 14 is under pressure, it will stop the top block 5 from moving, preventing the top block 5 from moving too much and causing damage to the part. The damper 18 inside the spring 17 can limit the spring 17 and prevent the spring 17 from causing the mounting block 19 to shake too much.

[0028] The top of the tail frame body 1 is fixedly connected to a connecting seat 11, and the bottom of the connecting seat 11 is provided with a base 12. The connecting seat 11 and the base 12 are provided with mounting grooves 22 on the left and right sides inside. The mounting grooves 22 are provided with mounting bolts 21 inside. The top of the mounting bolts 21 is provided with washers 20. The washers 20 are provided on the left and right sides of the top of the connecting seat 11. The connecting seat 11 is fixed by the mounting grooves 22 and the mounting bolts 21.

[0029] Specifically, such as Figure 1 and Figure 4As shown, the connecting seat 11 at the bottom of the tail frame body 1 is placed at the top of the tail frame body 1. When placing it, the mounting groove 22 is aligned. After alignment, the mounting bolt 21 is screwed into the inside of the mounting groove 22 to limit and fix the connecting seat 11, so that the tail frame body 1 can be installed in a suitable position. The washer 20 can prevent the mounting bolt 21 from loosening.

[0030] The computer software involved in the controller 2 hardware carrier in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carrier. In other words, the computer software involved is an essential technical feature for solving the aforementioned technical problem, that is, it constitutes a necessary technical feature for solving the technical problem of this application, but it is not a differentiating technical feature for solving the technical problem (not a point of technical improvement). The applicant has not made any technical improvements to the computer software involved in the aforementioned related hardware carrier, nor is it a key technical point of the invention.

[0031] Therefore, it is evident that the controller 2 and hydraulic cylinder 10 involved in this application are all physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, an improvement in the overall structure of the hydraulic tailstock of the vehicle in this application, in order to solve the corresponding technical problems to be solved by this application.

[0032] Working principle: In use, the connecting seat 11 at the bottom of the tailstock body 1 is placed at the top of the tailstock body 1. During placement, the mounting groove 22 is aligned. After alignment, the mounting bolt 21 is screwed into the mounting groove 22 to limit and fix the connecting seat 11, thereby allowing the tailstock body 1 to be installed in a suitable position. The washer 20 can prevent the mounting bolt 21 from loosening. When it is necessary to clamp parts, the hydraulic cylinder 10 is activated. The hydraulic cylinder 10 drives the mounting plate 8 to move, so that the top block 5 abuts against one side of the part to clamp and limit the part. When the mounting plate 8 drives the top block 5 to move, the limiting sliders 7 at the upper and lower ends of the mounting plate 8 will slide inside the limiting groove 4. The limiting groove 4 can be controlled by the limiting sliders 7. Mounting plate 8 limits the stability of top block 5 movement. When top block 5 clamps parts, mounting block 19 will squeeze spring 17. When squeezed to a certain position, mounting block 19 will contact pressure sensor 14 and squeeze pressure sensor 14. When pressure sensor 14 is under pressure, it will stop top block 5 movement to prevent excessive movement of top block 5 and damage to parts. The damper 18 inside spring 17 can limit spring 17 to prevent spring 17 from driving mounting block 19 to shake too much. When top block 5 needs to be replaced, rotate top block 5. Top block 5 drives threaded block 15 to rotate inside threaded groove 16 so that threaded block 15 can be unscrewed from inside threaded groove 16. After unscrewing, top block 5 can be easily replaced.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
