Technical Field

[0001] The utility model relates to the technical field of mechanical part processing, and specifically relates to a chamfering device for mechanical part processing. Background Technique

[0002] During the mechanical processing, chamfering is a common technological step, which is used to eliminate the sharp corners at the edges of parts to reduce stress concentration and enhance the strength and durability of parts. Most mechanical parts are circular workpieces. Therefore, a chamfering device is needed to process mechanical parts for subsequent use.

[0003] In the prior art, during the use of traditional chamfering devices, their clamping mechanisms are usually designed as fixed structures, which makes it difficult for the chamfering devices to be fully adapted when replacing mechanical parts of different sizes, restricting their ability to be widely applied. On the contrary, existing chamfering devices allow the replacement of clamping rings of different sizes. However, these clamping rings are usually fixed to the chamfering devices by bolts, which requires operators to use tools for disassembly and installation when replacing the clamping rings, increasing the operation complexity and time cost and reducing the efficiency and convenience of operators.

[0004] Therefore, a chamfering device for mechanical part processing is needed to solve the problem that during the use of existing chamfering devices, operators need to use tools to disassemble and install the clamping rings, resulting in inconvenience for operators to use.

[0007] Preferably, two sliding grooves are opened at the top of the plug-in block, fixing rods are inserted into the inner walls of the left and right sliding grooves, two pressing blocks are sleeved on the outer sides of the fixing rods, and a return spring is installed on the inner wall of the installation groove.

[0008] Preferably, the left and right pressing blocks are both slidably connected to the inner walls of the sliding grooves, and fixed connections are formed between the separated sides of the left and right pressing blocks and the clamping blocks.

[0009] Preferably, the return spring is installed between the left and right pressing blocks.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The chamfering device for machining mechanical parts proposed by the utility model drives the clamping block to be separated from the ring groove by squeezing the two squeezing blocks, so that it is convenient for operators to disassemble the clamping ring and can easily replace it.

Detailed implementation manners

[0024] In order to clearly and completely describe the purpose and technical solutions of the present utility model and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some but not all of the embodiments of the present utility model, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] Please refer to Figures 1-8 , the present utility model provides a technical solution: a chamfering device for machining mechanical parts, including a chamfering device body 1. A plurality of grinding mechanisms 2 are installed in the middle of the chamfering device body 1. A placing plate 4 is installed in the middle of the chamfering device body 1. A clamping ring 3 is arranged at the top of the chamfering device body 1. A plug-in block 5 is inserted into the top of the clamping ring 3, and it is fixedly installed between the plug-in block 5 and the electric push rod at the top of the chamfering device body 1, so as to conveniently drive the clamping ring 3 to move downward to clamp the circular workpiece, and then conveniently chamfer it through the grinding mechanism 2. An installation groove 10 is opened at the bottom of the plug-in block 5. On the left and right sides of the inner wall of the installation groove 10, clamping blocks 9 are installed; on the separated sides of the left and right clamping blocks 9, they are inserted into the inner wall of the annular groove 13, and the left and right clamping blocks 9 are symmetrically arranged. Thus, by symmetrically arranging the clamping blocks 9, it is convenient to clamp between the clamping ring 3 and the plug-in block 5 through the clamping blocks 9, and further prevent the clamping ring 3 from detaching from the plug-in block 5.

[0027] When replacing circular workpieces of different sizes and they cannot be matched with the clamping ring 3, at this time, drive the two clamping blocks 9 on the inner wall of the installation groove 10 to move towards the middle of the plug-in block 5, so that they are separated from the annular groove 13 inside the clamping ring 3. Then the operator removes the clamping ring 3 for replacement. After completion, the operator sleeved the clamping ring 3 on the outside of the plug-in block 5, and at the same time, drive the separated sides of the two clamping blocks 9 to be inserted into the inner wall of the annular groove 13, so as to conveniently clamp between the clamping ring 3 and the plug-in block 5, thus facilitating the operator to replace. After replacement, the operator places the circular workpiece on the top of the placing plate 4, and then starts the electric push rod at the top of the chamfering device body 1 to drive the clamping ring 3 to move downward, so as to clamp the workpiece on the top of the placing plate 4. At the same time, adjust the four grinding mechanisms 2 in the middle of the chamfering device body 1. After adjustment, start the motor at the bottom of the chamfering device body 1 to drive the placing plate 4 to rotate, and synchronously drive the clamping ring 3 to rotate with the placing plate 4, so as to improve the chamfering efficiency of the chamfering device body 1.

[0028] Embodiment 2

[0029] On the basis of Embodiment 1, in order to facilitate the operator to remove the clamping ring 3, two sliding grooves 8 are opened at the top of the plug-in block 5, and fixing rods 7 are inserted into the inner walls of the left and right sliding grooves 8. Through the installation of the fixing rods 7, the two plug-in blocks 5 can move more smoothly, and the fixing rods 7 can be prevented from detaching from the plug-in blocks 5. Two extrusion blocks 6 are sleeved on the outer sides of the fixing rods 7, and a return spring 11 is installed on the inner wall of the installation groove 10.

[0030] When the clamping ring 3 needs to be replaced, first squeeze the two extrusion blocks 6 to make them slide along the outer sides of the fixing rods 7, and at the same time drive the clamping blocks 9 fixedly connected to their bottoms to move along the inner wall of the installation groove 10 towards the middle of the plug-in block 5, so that the clamping blocks 9 are separated from the ring grooves 13. At this time, the operator can disassemble and replace the clamping ring 3. After completion, reset it, which is convenient for the operator to replace the clamping ring 3.

[0031] Embodiment 3

[0032] On the basis of Embodiment 2, in order to facilitate driving the clamping blocks 9 to reset so as to clamp between the clamping ring 3 and the plug-in block 5, the left and right extrusion blocks 6 are both slidably connected to the inner walls of the sliding grooves 8, and the separated sides of the left and right extrusion blocks 6 are both fixedly connected to the clamping blocks 9. Thus, by squeezing the two extrusion blocks 6 to slide along the inner walls of the sliding grooves 8 towards the middle of the plug-in block 5, the two clamping blocks 9 are driven to move along the inner wall of the installation groove 10 and separate from the clamping ring 3, which is convenient for the operator to disassemble and assemble the clamping ring 3; the return spring 11 is installed between the left and right extrusion blocks 6. Thus, when the operator releases the extrusion blocks 6, the elastic force of the return spring 11 is used to push the two clamping blocks 9 to move away from each other, and at the same time make the separated sides of them inserted into the inner walls of the ring grooves 13, which is convenient for the operator to install the clamping ring 3 on the outside of the plug-in block 5.

[0033] After the operator has completed the replacement, since the two clamping blocks 9 will squeeze the return spring 11 on the inner wall of the installation groove 10 when moving towards each other, at this time the operator releases the extrusion blocks 6, and thus the elastic force of the return spring 11 is used to push the clamping blocks 9 on its left and right sides to move away from each other and make them inserted into the inner walls of the ring grooves 13, which is convenient for driving the clamping blocks 9 to reset, and the elastic force of the return spring 11 is used to always keep the clamping blocks 9 in the inserted state, thus preventing the clamping ring 3 from detaching from the outside of the plug-in block 5.

[0034] Embodiment 4

[0035] On the basis of Embodiment 3, in order to facilitate the rotation of the clamping ring 3 outside the plug-in block 5, ball bearings 12 are installed on both the upper and lower sides of the clamping block 9. A ring groove 13 is formed inside the clamping ring 3. When the clamping block 9 is inserted into the inner wall of the ring groove 13, the ball bearings 12 on its upper and lower sides are driven to fit against the inner wall of the ring groove 13. The ball bearings 12 on the upper and lower sides are symmetrically arranged, and the separated sides of the ball bearings 12 on the upper and lower sides are both in contact with the inner wall of the ring groove 13. When the circular workpiece is clamped downward by the clamping ring 3, the motor at the bottom of the chamfering device body 1 drives the placement plate 4 to rotate, thereby driving the workpiece on its top to rotate, synchronously driving the clamping ring 3 to rotate, thus facilitating the chamfering of the workpiece and improving the chamfering efficiency.

[0036] When the chamfering device body 1 is in use, at this time, since the placement plate 4 rotates, it will drive the clamping ring 3 in a clamping state with it to rotate synchronously. Since ball bearings 12 are installed on both the upper and lower sides of the clamping block 9, and the two ball bearings 12 on the upper and lower sides are symmetrically arranged and in contact with the inner wall of the ring groove 13 at the same time, when the clamping ring 3 rotates, it contacts through the surface between the ring groove 13 and the ball bearings 12, and the ball bearings 12 rotate, thus facilitating the rotation of the clamping ring 3 outside the plug-in block 5 and continuing to clamp the workpiece, thereby improving the use effect of the chamfering device body 1.

[0037] During actual use, in order to facilitate the rotation of the clamping ring 3 outside the plug-in block 5, ball bearings 12 are installed on both the upper and lower sides of the clamping block 9. A ring groove 13 is formed inside the clamping ring 3. When the clamping block 9 is inserted into the inner wall of the ring groove 13, the ball bearings 12 on its upper and lower sides are driven to fit against the inner wall of the ring groove 13. The ball bearings 12 on the upper and lower sides are symmetrically arranged, and the separated sides of the ball bearings 12 on the upper and lower sides are both in contact with the inner wall of the ring groove 13. When the circular workpiece is clamped downward by the clamping ring 3, the motor at the bottom of the chamfering device body 1 drives the placement plate 4 to rotate, thereby driving the workpiece on its top to rotate, synchronously driving the clamping ring 3 to rotate, thus facilitating the chamfering of the workpiece and improving the chamfering efficiency.

[0038] During actual use, when replacing circular workpieces of different sizes and they cannot be used in matching with the clamping ring 3, at this time, the two clamping blocks 9 on the inner wall of the installation groove 10 are driven to move towards the middle of the insertion block 5, so that they are disengaged from the annular groove 13 inside the clamping ring 3. Then, the operator removes and replaces the clamping ring 3. After completion, the operator sleeved the clamping ring 3 on the outside of the insertion block 5, and at the same time, the two sides where the clamping blocks 9 are separated are inserted into the inner wall of the annular groove 13, thereby facilitating the clamping between the clamping ring 3 and the insertion block 5, and thus facilitating the operator to replace. After the replacement is completed, the operator places the circular workpiece on the top of the placing plate 4. Then, the electric push rod at the top of the chamfering device body 1 is started to drive the clamping ring 3 to move downward, so as to clamp the workpiece on the top of the placing plate 4. At the same time, the four grinding mechanisms 2 in the middle of the chamfering device body 1 are adjusted. After the adjustment is completed, the motor at the bottom of the chamfering device body 1 is started to drive the placing plate 4 to rotate, and the clamping ring 3 is synchronously driven to rotate with the placing plate 4, thereby improving the chamfering efficiency of the chamfering device body 1.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
