Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a clamping device for the inner hole end face of a workpiece processed by a grinding machine. Background Technology

[0002] The clamping device for the inner hole end face of a workpiece processed by a grinding machine is a type of fixed clamping device that can stably clamp the inner hole end face of the workpiece during processing, thereby ensuring its stability during subsequent processing by the grinding machine and guaranteeing the processing effect.

[0003] Existing clamping devices for the inner hole end face of workpieces processed by grinding machines have limited contact area between the clamping blocks and the inner hole end face of the workpiece after they are spread out. This makes it difficult to ensure that the outer wall of the clamping blocks is in contact with the inner hole end face of workpieces of different sizes to improve the clamping strength. Therefore, we propose a clamping device for the inner hole end face of workpieces processed by grinding machines. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A clamping device for grinding the inner end face of a workpiece using a grinding machine includes: a clamping unit and a reinforcing component; the clamping unit includes a clamping seat at the front end, a cylinder mounted at the rear end of the clamping seat, a pressure rod mounted at the front end of the cylinder inside the clamping seat, and a circular hole opened on the clamping seat; the reinforcing component includes multiple sets of sliding grooves arranged on the clamping seat, clamping blocks movably installed in each of the sliding grooves, mounting openings on the outside of each of the clamping blocks, clamping plates movably installed in each of the mounting openings, a middle rubber pad and a side rubber pad respectively fixedly installed at the center and on both sides of the upper end of the clamping plate, an outward protrusion provided at the outer end of each of the side rubber pads, and a middle pressure plate fixedly installed inside each of the middle rubber pads.

[0007] Preferably, each of the side rubber pads has a side mounting cavity in its upper part, and a side clamping plate is fixedly installed in the top of each side mounting cavity. The tops of both the middle clamping plate and the side clamping plate are curved surfaces.

[0008] Preferably, the bottom of the side clamping plates inside the side mounting cavity is also fixedly mounted with first springs.

[0009] Preferably, the clamping plate and the mounting opening are respectively provided with a first mounting hole and a second mounting hole on both sides.

[0010] Preferably, fixing screws are also movably installed in the first mounting hole and the second mounting hole at the upper end of the clamp.

[0011] Preferably, a baffle is fixedly installed on one side of each clamping block, and a second spring is fixedly installed on the upper end of each baffle.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1. In this utility model, when the inner hole end face of the workpiece is clamped by the clamping device, the pressure rod driven by the cylinder in the clamping seat will press the multiple sets of clamping blocks in the clamping seat to press the clamping plate at the outer end of the clamping block to the inner hole end face of the workpiece. The middle rubber pad at the center of the outer end of the clamping plate will be deformed and tightly attached to the middle of the pressing part during the pressing process by the middle pressure plate at the inner end. The side rubber pads on both sides of the outer end of the clamping plate will deform during the pressing process to press the side pressure plate and the first spring inside the side rubber pad, thereby also causing the outer protrusion to deform and attach to the inner hole end face, thereby expanding the pressing area of ​​the outer end of the clamping block to improve its pressing strength and ensure the stability during processing. Moreover, in the clamping of the inner hole end face of workpieces of different sizes, this clamping block can enhance its pressing area and thus ensure its clamping strength.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a clamping device for the inner hole end face of a workpiece processed by a grinding machine.

[0025] Example 1:

[0026] Combination Figure 1-5 As shown, this utility model provides a clamping device for machining the inner end face of a workpiece using a grinding machine, comprising: a clamping device 100 and a reinforcing component 200; the clamping device 100 includes a clamping seat 101 at the front end, a cylinder 102 mounted at the rear end of the clamping seat 101, a pressure rod 103 mounted at the front end of the cylinder 102 inside the clamping seat 101, and a circular hole 104 opened on the clamping seat 101; the reinforcing component 200 includes multiple sets of sliding grooves 201 arranged on the clamping seat 101, clamping blocks 202 movably installed in the sliding grooves 201, mounting openings 203 on the outside of the clamping blocks 202, clamping plates 204 movably installed in the mounting openings 203, a middle rubber pad 205 and a side rubber pad 206 fixedly installed at the center and both sides of the upper end of the clamping plate 204, and the outer ends of the side rubber pads 206 are provided with A central clamping plate 208 is fixedly installed in the outer protrusion 207 and the central rubber pad 205. A side mounting cavity 209 is opened in the upper part of the side rubber pad 206. A side clamping plate 210 is fixedly installed in the top of the side mounting cavity 209. The tops of the central clamping plate 208 and the side clamping plate 210 are both arc surfaces. A first spring 211 is also fixedly installed at the bottom of the side clamping plate 210 in the side mounting cavity 209. A first mounting hole 212 and a second mounting hole 213 are respectively opened on both sides of the clamping plate 204 and the mounting opening 203. A fixing screw 214 is also movably installed in the first mounting hole 212 and the second mounting hole 213 at the upper end of the clamping plate 204. A baffle 215 is fixedly installed on one side of the clamping block 202. A second spring 216 is fixedly installed on the upper end of the baffle 215.

[0027] Specifically, the clamping device for the inner hole end face of the workpiece processed by the grinding machine is a fixed clamping device that can stably clamp the inner hole end face of the workpiece during processing, thereby ensuring its stability during subsequent grinding machine processing. When the inner hole end face of the workpiece is clamped by the clamping device 100, the pressure rod 103 driven by the cylinder 102 in the clamping seat 101 will press the multiple sets of clamping blocks 202 in the clamping seat 101, so as to press the clamping plate 204 at the outer end of the clamping block 202 onto the inner hole end face of the workpiece. The central rubber pad 205 at the outer end of the clamping plate 204 will deform and fit tightly against the middle of the pressing part during the pressing process, supported by the central pressure plate 208 at the inner end. The outer protrusions 207 of the side rubber pads 206 on both sides of the outer end of the clamping plate 204 will deform during the pressing process, so as to press the side pressure plate 210 and the first spring 211 inside the side rubber pad 206, thereby also causing the outer protrusions 207 to deform. The clamping block 202 is attached to the inner end face of the workpiece, thereby expanding the clamping area of ​​the outer end of the clamping block 202 to improve its clamping strength and ensure stability during processing. In clamping workpieces with different sizes of inner end faces, the clamping block 202 can enhance its clamping area and thus ensure its clamping strength. At the same time, after the middle rubber pad 205 and side rubber pad 206 on the outer end clamping plate 204 of the clamping block 202 wear and are damaged after long-term use, the clamping plate 204 can be easily disassembled from the outer end of the clamping block 202 for easy replacement of the entire clamping plate 204, so as to ensure the clamping effect of the clamping device 100 on the inner end face of the workpiece. The second spring 216 fixedly installed on the upper end of the baffle 215 on one side of the clamping block 202 is mainly used to move the clamping block 202 in the slide groove 201 back through the second spring 216 when the cylinder 102 moves back the pressure rod 103, so that the clamping seat 101 can be moved out of the inner hole of the workpiece.

[0028] Working principle and usage process of this utility model:

[0029] Before the workpiece is clamped by the grinding machine, the workpiece is first placed on the outer end of the clamping seat 101. After the clamping seat 101 is in the inner hole of the workpiece, the cylinder 102 at the rear end of the clamping seat 101 is activated. After the cylinder 102 is activated, the pressure rod 103 at the front end of the drive is moved forward. During the forward movement of the pressure rod 103, multiple sets of clamping blocks 202 on the outer side of the pressure rod 103 are moved outward along the slide groove 201. During the outward movement of the clamping blocks 202 along the slide groove 201, the clamping plates 204 at the outer end of the clamping blocks 202 are pressed against the inner hole end face of the workpiece. During the pressing of the clamping plates 204 against the inner hole end face of the workpiece, the central rubber pad 205 will first adhere to the inner hole end face of the workpiece, and after adhering, it will be completely deformed by compression. The side rubber pads 206 on both sides of the clamping plate 204, after the middle rubber pad 205 deforms, press the inner side clamping plate 210 and the first spring 211 to completely conform to the inner end face of the workpiece. This ensures that during workpiece clamping, the middle rubber pad 205 and side rubber pads 206 at the outer end of the clamping block 202 deform and press against the inner end face of the workpiece, increasing the clamping area and enhancing the clamping effect. At the same time, if the middle rubber pad 205 and side rubber pads 206 at the outer end of the clamping plate 204 are damaged, the fixing screws 214 on both sides can be removed for easy replacement of the entire clamping plate 204, thus ensuring the clamping effect of the clamping device 100 during use.

[0030] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
