Description

Technical Field

[0001] This utility model relates to the technical field of workpiece production and processing fixtures, specifically a spring chuck with a workpiece positioning structure. Background Technology

[0002] A spring collet is a mechanical device used to clamp workpieces, widely used in machining equipment such as lathes, milling machines, and grinding machines. Its main function is to clamp the workpiece through elastic deformation, ensuring its stability during machining. Traditional spring collets are typically made of elastic materials and have multiple jaws. External force (such as a nut or pull rod) causes the jaws to contract, thus clamping the workpiece. However, traditional spring collets have some limitations in clamping workpieces: insufficient positioning accuracy, limited applicability, and uneven clamping force. Therefore, spring collets with workpiece positioning structures represent a significant improvement over traditional collet technology. By introducing positioning devices and optimizing the design, clamping accuracy, stability, and applicability are significantly improved, meeting the demands of modern high-precision machining.

[0003] Current spring collets do not provide a stable clamping and fixing effect when in use, and their clamping range is small, which limits their clamping capabilities. Utility Model Content

[0004] The purpose of this invention is to provide a spring chuck with a workpiece positioning structure, which solves the problem that the current chuck cannot provide a stable clamping and fixing effect and has a small clamping range, which limits its clamping performance.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a spring chuck with a workpiece positioning structure, including a support plate assembly, a braking assembly installed on the rear side of the support plate assembly, chuck assemblies installed on both ends of the front side of the braking assembly, limit assemblies installed on both sides of the chuck assembly, and the limit assemblies installed on both ends of the inner side of the support plate assembly.

[0007] The braking assembly includes a connecting bracket connected to the rear top of the mounting housing, and a mounting rail is provided in the middle of the connecting bracket. A pneumatic telescopic pump is installed in the middle of the mounting rail, a push rod is installed inside the pneumatic telescopic pump, and a push head is installed at the end of the push rod.

[0008] Furthermore, the support plate assembly includes a mounting housing, a mounting base is mounted on the bottom of the mounting housing, and a positioning plate is mounted on the top center of the mounting base.

[0009] Furthermore, the clamp assembly includes rollers, which are mounted on both sides of the push head and are limited to the top of the clamping rod. The clamping rod has a through groove inside, and a positioning rod is limited to the inside of the through groove. A silicone pad is connected to the inner side of the end of the clamping rod. Limiting plates are installed on both sides of the positioning rod, and return springs are installed on the outer periphery of both sides of the positioning rod. The return springs are installed between the clamping rod and the inner wall of the limiting plate.

[0010] Furthermore, the limiting component includes a support rod, which is installed on the inner wall of the mounting housing, and a support spring is installed around the support rod. A telescopic clamp is installed at the end of the support spring, and a limiting post is installed at the top center of the telescopic clamp. The limiting post is installed at the middle position where the two clamping rods intersect.

[0011] Furthermore, a telescopic hole is provided in the middle of the rear side of the mounting housing, and a pusher is correspondingly provided in the middle of the telescopic hole.

[0012] Furthermore, a limiting mounting hole is provided in the middle of the clamping rod, and a limiting post is installed in the middle of the limiting mounting hole.

[0013] This utility model has the following beneficial effects:

[0014] (1) The spring chuck with workpiece positioning structure of this utility model has a braking component installed on the device, which enables the chuck assembly to achieve clamping positioning effect by driving the spring through the braking component when using the device. This makes the positioning flexible and stable when performing clamping work.

[0015] (2) The spring chuck with workpiece positioning structure of this utility model can provide further stability by installing a limiting component on the device. When using this device, the movement range of the chuck component can be specified by the limiting component.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4 As shown, this utility model is a spring chuck with a workpiece positioning structure, including a support plate assembly 1, a braking assembly 2 installed on the rear side of the support plate assembly 1, a chuck assembly 3 installed on both ends of the front side of the braking assembly 2, and limit assemblies 4 installed on both sides of the chuck assembly 3. The limit assemblies 4 are installed on both ends of the inner side of the support plate assembly 1.

[0026] The braking assembly 2 includes a connecting bracket 201, which is connected to the rear top of the mounting housing 101. The connecting bracket 201 has a mounting rail 202 in the middle, and a pneumatic telescopic pump 203 is installed in the middle of the mounting rail 202. A push rod 204 is installed inside the pneumatic telescopic pump 203, and a push head 205 is installed at the end of the push rod 204. The pneumatic telescopic pump 203 drives the push rod 204 to move back and forth by air pressure. The push head 205 at the end of the push rod 204 transmits power to the clamp assembly 3. The push head 205 moves linearly through the mounting rail 202, pushing the roller 301 of the clamp assembly 3, thereby opening or closing the clamp rod 302.

[0027] By installing a braking component 2 on the device, when using this device, the braking component 2 can achieve a clamping and positioning effect by driving the chuck component 3 through a spring. This provides flexibility and stability in positioning during clamping operations.

[0028] The support plate assembly 1 includes a mounting housing 101, a mounting base 102 is mounted on the bottom of the mounting housing 101, and a positioning plate 103 is mounted on the top center of the mounting base 102.

[0029] The chuck assembly 3 includes rollers 301, which are mounted on both sides of the pusher 205. The rollers 301 are also positioned on the top of the clamping rod 302. The clamping rod 302 has a through groove inside, and a positioning rod 303 is positioned inside the through groove. A silicone pad 306 is connected to the inner side of the end of the clamping rod 302. Limiting plates 305 are mounted on both sides of the positioning rod 303, and return springs 304 are mounted on the outer periphery of both sides of the positioning rod 303. The return springs 304 are installed between the clamping rod 302 and the inner wall of the limiting plates 305. When the braking assembly is working, the pusher 205 pushes the rollers 301, thereby driving the clamping rod 302 to move. The silicone pad 306 at the end of the clamping rod 302 is used to clamp the workpiece to ensure that the workpiece does not move during processing.

[0030] The limiting component 4 includes a support rod 401, which is installed on the inner wall of the mounting housing 101. A support spring 402 is installed around the support rod 401, and a telescopic clamping plate 403 is installed at the end of the support spring 402. A limiting post 404 is installed at the top center of the telescopic clamping plate 403, and the limiting post 404 is installed at the midpoint of the intersection of the two clamping rods 302. The limiting component 4 is used to limit the range of motion of the clamping rods 302 to ensure that the clamping force is moderate. The support rod 401 and the support spring 402 work together to allow the telescopic clamping plate 403 to move elastically within a certain range. The limiting post 404 is installed in the limiting mounting hole 3021 of the clamping rod 302 to prevent the clamping rod from opening or closing excessively.

[0031] A telescopic hole 1011 is provided in the middle of the rear side of the mounting housing 101, and a push head 205 is provided in the middle of the telescopic hole 1011.

[0032] A limit mounting hole 3021 is provided in the middle of the clamping rod 302, and a limit post 404 is installed in the middle of the limit mounting hole 3021.

[0033] In use, the support plate assembly 1 serves as the basic structure of the entire chuck. The support plate assembly 1 includes a mounting housing 101 and a mounting base 102, used to fix and support other components. The positioning plate 103 is used for initial workpiece positioning. The braking assembly 2 is the power source for the chuck, including a pneumatic telescopic pump 203 and a push rod 204. The pneumatic telescopic pump 203 drives the push rod 204 to move back and forth via air pressure. The push head 205 at the end of the push rod 204 transmits power to the chuck assembly 3. The push head 205 is connected to the mounting rail 2. The 02 component moves linearly, pushing the roller 301 of the chuck assembly 3, thereby opening or closing the clamping rod 302. The chuck assembly 3 is connected to the pusher 205 of the braking assembly 2 via the roller 301. When the braking assembly is activated, the pusher 205 pushes the roller 301, which in turn drives the clamping rod 302 to move. The silicone pad 306 at the end of the clamping rod 302 is used to clamp the workpiece, ensuring that the workpiece does not move during processing. The limiting assembly 4 is used to limit the range of motion of the clamping rod 302 to ensure that the clamping force is moderate. The support rod 401 and the support spring 402 work together to allow the telescopic clamping plate 403 to move elastically within a certain range. The limiting post 404 is installed in the limiting mounting hole 3021 of the clamping rod 302 to prevent the clamping rod from opening or closing excessively. When the braking assembly 2 stops working, the return spring 304 pulls the clamping rod 302 back to the initial position and releases the workpiece. When using the whole system, the workpiece is first placed on the positioning plate 103 for initial positioning. Then, the pneumatic telescopic pump 203 is started to push the push rod 204 and the push head 205 forward. The push head 205 further pushes the roller 301, causing the clamping rod 302 to close inward. The silicone pad 306 clamps the workpiece. At the same time, the limiting post 404 and the support spring 402 ensure that the clamping force is moderate to avoid damage to the workpiece or overload of the chuck. Finally, after the processing is completed, the pneumatic telescopic pump 203 stops working, and the return spring 304 pulls the clamping rod 302 back to its original position and releases the workpiece.
