Description

Technical Field

[0001] This utility model relates to the technical field of machine tool parts processing, and in particular to a clamping device for machine tool parts processing. Background Technology

[0002] Machine tool parts processing refers to the process of cutting, shaping, and finishing metal materials using various machining methods such as lathes, milling machines, and grinding machines to manufacture and repair various parts required for machine tools. This process typically includes turning, milling, drilling, and grinding, and can process raw materials into high-precision mechanical components such as gears, bearing housings, and guide rails according to design requirements. These components play crucial roles in supporting, transmitting, and positioning the machine tool during operation.

[0003] The prior art, such as the clamping device for forklift parts processing disclosed in application number CN202011079298.1, uses a second electric push rod to drive the clamping linkage rod and clamping plate to clamp and fix the parts. It has a better clamping and fixing effect on parts with special shapes, and can better control the clamping force on the parts, effectively avoiding damage to the parts due to excessive clamping force. It can clamp parts with special shapes more firmly, which is conducive to better processing of the parts.

[0004] However, the above-mentioned clamping device uses the method of clamping and fixing the outer surface of the part. However, in practical applications, when there is a large area to be processed on the outer surface of the part, the clamping part and the area to be processed are prone to positional interference, which causes the clamping part to block the processing path or restrict the access of the processing tool, thereby affecting the integrity and accuracy of the processing and making it difficult to meet the needs of complex processing technology. Utility Model Content

[0005] In view of the fact that the existing clamping devices use an outer surface clamping method, which is prone to positional interference when the parts are to be processed over a large area, affecting the integrity and accuracy of the processing and making it difficult to meet the needs of complex processing, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a machine tool parts processing clamping device, which aims to solve the problem that existing clamping devices, due to their use of external surface clamping, are prone to positional interference when the parts are to be processed over a large area, affecting the integrity and accuracy of the processing and making it difficult to meet complex processing requirements.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a machine tool parts processing clamping device, including a processing table, a rotating mechanism, and a clamping mechanism. The rotating mechanism includes a rotating seat rotatably installed inside the processing table. The clamping mechanism includes a fixed block fixedly installed on the upper surface of the rotating seat. A top groove is formed inside the fixed block. A top rod is slidably installed inside the top groove. A second spring is installed between the upper part of the top rod and the upper surface of the top groove. Clamping blocks are rotatably installed on both sides of the top rod through a second rotating shaft. A sliding groove is formed inside the rotating seat. A sliding block is slidably installed inside the sliding groove. An inclined surface is provided on the upper surface of the sliding block and the lower surface of the top rod. The sliding block is in contact with the lower surface of the top rod through the inclined surface.

[0008] In a preferred embodiment of the machine tool parts processing clamping device of this utility model, a drive motor is fixedly installed at one end of the sliding groove, and a threaded screw is driven at the output end of the drive motor.

[0009] In a preferred embodiment of the machine tool parts processing clamping device of this utility model, the sliding block is threadedly mounted on the surface of the threaded lead screw.

[0010] In a preferred embodiment of the machine tool parts processing clamping device of this utility model, the middle part of the surface of the clamping block is rotatably mounted on the inner side of the fixed block via a first rotating shaft.

[0011] As a preferred embodiment of the machine tool parts processing clamping device of this utility model, a number of sets of protrusions are fixedly installed on the upper outer side of the rotating seat.

[0012] As a preferred embodiment of the machine tool parts processing clamping device of this utility model, a sliding groove is provided on one side of the upper surface of the processing table, and a sliding rod is fixedly installed inside the sliding groove.

[0013] As a preferred embodiment of the machine tool parts processing clamping device of this utility model, a slider is slidably mounted on the surface of the slide rod, a handle is fixedly mounted on the upper surface of the slider, and a first spring is installed between one side surface of the slider and the inner wall of the slide groove.

[0014] In a preferred embodiment of the machine tool parts processing clamping device of this utility model, a locking block is fixedly installed on the side surface of the slider away from the first spring.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. This utility model, through its clamping mechanism, allows the parts to be placed on the processing table. The drive motor then rotates the threaded screw, causing the inclined surface of the sliding block to lift the top rod upwards. The top rod then lifts the inner end of the clamping block upwards, pressing the outer end of the clamping block downwards. This clamps and fixes the inner step of the parts by squeezing and holding it. By squeezing and holding the parts from the inner step through the clamping mechanism, the obstruction of the processing area by the traditional outer clamping method is avoided, effectively improving the integrity and accuracy of the processing. At the same time, it is easy to operate and provides stable clamping, meeting the needs of complex processing techniques.

[0017] 2. This utility model, through its rotating mechanism, allows for easy adjustment of the rotation angle of the part. When the part needs to be rotated, the handle is pulled outward, causing the locking block to slide outward. After the locking block is released, the rotating seat is manually rotated. Once the angle has been rotated, the handle is released, and the first spring's return force locks the locking block onto the protrusion, thus locking the rotation angle of the rotating seat. This enables rapid adjustment and precise positioning of the part's processing angle. The operation is simple and the locking is reliable, effectively improving processing flexibility and efficiency, meeting multi-angle processing needs. At the same time, the compact structure and rapid reset enhance the ease of use and stability of the equipment. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1 , Figure 3 and Figure 4 This is the first embodiment of the present invention, which provides a machine tool parts processing clamping device. This machine tool parts processing clamping device includes a processing table 1, a rotating mechanism 2, and a clamping mechanism 3. The rotating mechanism 2 includes a rotating seat 201 rotatably installed inside the processing table 1. The clamping mechanism 3 includes a fixing block 307 fixedly installed on the upper surface of the rotating seat 201. The fixing block 307 has a top groove 308 inside. A top rod 306 is slidably installed inside the top groove 308. A second spring 309 is installed between the upper part of the top rod 306 and the upper surface of the top groove 308. Clamping blocks 310 are rotatably installed on both sides of the top rod 306 through a second rotating shaft 312. A sliding groove 301 is opened on the inner side of the rotating seat 201. A sliding block 304 is slidably installed inside the sliding groove 301. An inclined surface 305 is provided on the upper surface of the sliding block 304 and the lower surface of the top rod 306. The sliding block 304 is in contact with the lower surface of the top rod 306 through the inclined surface 305.

[0027] A drive motor 302 is fixedly installed at one end of the sliding groove 301, and a threaded screw 303 is installed at the output end of the drive motor 302.

[0028] The sliding block 304 is threadedly mounted on the surface of the threaded screw 303.

[0029] The middle part of the surface of the clamping block 310 is rotatably mounted on the inside of the fixing block 307 via the first rotating shaft 311.

[0030] During use, the parts to be processed are first placed on the processing table 1. The drive motor 302 is started to drive the threaded screw 303 to rotate. The threaded screw 303 drives the sliding block 304 to slide in the sliding groove 301. The inclined surface 305 on the upper surface of the sliding block 304 contacts the inclined surface 305 on the lower surface of the push rod 306 and pushes the push rod 306 to slide upward along the top groove 308. The push rod 306 rises against the elastic force of the second spring 309. The upper part of the push rod 306 drives the inner end of the clamping block 310 to lift upward through the second rotating shaft 312. The outer end of the clamping block 310 is pressed downward by the rotation of the first rotating shaft 311, thereby forming a squeezing and clamping fixation on the stepped part inside the part.

[0031] Example 2

[0032] Reference Figures 2-3This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a number of sets of protrusions 202 are fixedly installed on the upper outer side of the rotating seat 201.

[0033] A slide groove 203 is provided on one side of the upper surface of the processing table 1, and a slide rod 204 is fixedly installed inside the slide groove 203.

[0034] A slider 205 is slidably mounted on the surface of the slider 204. A handle 206 is fixedly mounted on the upper surface of the slider 205. A first spring 207 is installed between one side surface of the slider 205 and the inner wall of the groove 203.

[0035] A locking block 208 is fixedly installed on the side of the slider 205 away from the first spring 207.

[0036] During use, when it is necessary to rotate the part, the operator pulls the handle 206 outward. The handle 206 drives the slider 205 to slide outward along the slide bar 204 in the slide groove 203. At the same time, the locking block 208 on one side of the slider 205 moves outward, disengaging from the locked state with the upper outer protrusion 202 of the rotating seat 201. At this time, the rotating seat 201 is no longer fixed and can rotate freely. After the operator manually rotates the rotating seat 201 to the required processing angle, the handle 206 is released. Under the action of the return spring force, the first spring 207 pushes the slider 205 to slide inward along the slide bar 204. The slider 205 drives the locking block... 208 re-engages between the protrusions 202 on the rotating seat 201, completing the precise positioning and locking of the rotation angle of the rotating seat 201. Throughout the process, the cooperation between the slide groove 203 and the slide rod 204 ensures the smooth movement of the slider 205, the first spring 207 provides a reliable restoring force, and the engagement between the locking block 208 and the protrusion 202 achieves the firmness of the angle lock, thereby realizing the rapid adjustment and precise positioning of the processing angle of the parts. The operation is simple and the locking is reliable, effectively improving the processing flexibility and efficiency, meeting the needs of multi-angle processing, while the structure is compact and the reset is rapid, enhancing the ease of use and stability of the equipment.

[0037] The remaining structure is the same as that in Example 1.

[0038] Based on embodiments 1-2, the working principle of this utility model is as follows: First, the part to be processed is placed on the processing table 1. The drive motor 302 is started to drive the threaded screw 303 to rotate. The threaded screw 303 drives the sliding block 304 to slide in the sliding groove 301. The inclined surface 305 on the upper surface of the sliding block 304 contacts the inclined surface 305 on the lower surface of the push rod 306 and pushes the push rod 306 to slide upward along the top groove 308. The push rod 306 rises against the elastic force of the second spring 309. The upper part of the push rod 306 drives the inner end of the clamping block 310 to rise upward through the second rotating shaft 312, while the outer end of the clamping block 310 is pressed downward by the rotation of the first rotating shaft 311, thereby forming a squeezing and clamping fixation on the stepped part inside the accessory; when it is necessary to turn the accessory, the operator pulls the handle 206 outward, the handle 206 drives the slider 205 to slide outward along the slide rod 204 in the slide groove 203, and at the same time, the locking block 208 on one side of the slider 205 moves outward accordingly, disengaging. When the rotating seat 201 is locked to the upper outer protrusion 202, it is no longer fixed and can rotate freely. After the operator manually rotates the rotating seat 201 to the required processing angle, he releases the handle 206. Under the action of the reset force, the first spring 207 pushes the slider 205 to slide inward along the slide rod 204. The slider 205 drives the locking block 208 to re-engage between the protrusions 202 on the rotating seat 201, thus completing the precise positioning and locking of the rotation angle of the rotating seat 201. Throughout the process, the cooperation between the slide groove 203 and the slide rod 204 ensures that the slider 205 moves smoothly, the first spring 207 provides a reliable reset force, and the engagement between the locking block 208 and the protrusion 202 ensures the firmness of the angle lock. This enables the rapid adjustment and precise positioning of the processing angle of the parts. The operation is simple and the locking is reliable, which effectively improves the processing flexibility and efficiency, meets the needs of multi-angle processing, and at the same time, the structure is compact and the reset is fast, which enhances the ease of use and stability of the equipment.
