Description

Technical Field

[0001] The invention belongs to the technical field of cemented carbide surface treatment, in particular to a cemented carbide surface treatment device with a fast workpiece clamping mechanism. Background Art

[0002] In the surface treatment process of cemented carbide workpieces, especially for high-precision operations such as precision grinding and polishing of cemented carbide cutting blades, stable clamping of workpieces is a key step to ensure processing quality and efficiency. Traditional clamping methods generally have a series of problems, which significantly restrict the smooth progress of the production process. Specifically, these traditional methods often lead to low clamping efficiency, that is, it takes a long time to complete the fixation of the workpiece, thereby reducing the overall production rhythm; at the same time, the clamping stability is insufficient, and it is easy to cause shaking or displacement during the processing process, which directly affects the accuracy and consistency of the surface treatment; in addition, the operation steps are cumbersome and complicated, which increases the cognitive burden and difficulty of the operator.

[0003] When faced with the needs of diversified and frequently changing workpieces, such as processing carbide cutting blades of various shapes, specifications and sizes such as round, triangular, quadrilateral, diamond, etc., the limitations of traditional clamping methods are becoming more and more prominent. These workpieces have different shapes, which puts higher requirements on the flexibility and adaptability of the clamping system. Traditional methods are often difficult to adjust quickly to meet the clamping needs of different workpieces, which not only prolongs the changeover time and reduces production efficiency, but may also cause damage to the workpiece or substandard processing quality due to improper clamping, further increasing the labor intensity and cost loss of operators. Summary of the invention

[0049] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] like Figures 1 to 7 As shown, the present invention provides a first embodiment of a cemented carbide surface treatment device with a rapid workpiece clamping mechanism, including a workpiece clamping mechanism 100, wherein the workpiece clamping mechanism 100 includes an operating platform 1, a base 2, a driving assembly 3, a clamping assembly 4 and other parts.

[0051] like Figure 2 and 3As shown, the operating platform 1 has an upper surface 11 and a lower surface 12, and at least one mounting hole 13, and the mounting hole 13 runs through the upper surface 11 and the lower surface 12. The base 2 has a base top surface 21. A wall portion 14 is provided extending downward around the edge of the lower surface 12 of the operating platform 1, and at least two positioning guide components 15 are provided on the wall portion 14. At least two positioning guide grooves 22 corresponding to the positioning guide components 15 are provided in the base 2, and the positioning guide components 15 can move in the positioning guide grooves 22. The driving component 3 is arranged between the operating platform 1 and the base 2, and is used to drive the operating platform 1 to rise and fall. At least one clamping component 4 is detachably fixedly mounted in the mounting hole 13 of the operating platform 1.

[0052] Of course, if Figure 7 As shown, a plurality of mounting holes 13 can be provided on the operating platform 1, so that a plurality of clamping assemblies 4 can be flexibly and detachably mounted in the corresponding mounting holes 13 of the operating platform 1. In this way, suitable clamping assemblies 4 can be selected for combined installation according to the shape and size requirements of different cemented carbide workpieces, thereby meeting the diverse workpiece surface treatment requirements.

[0053] like Figure 2 and 4As shown, each clamping assembly 4 includes a clamping body 41, at least one clamping member 42, and at least one pushing member 43. The clamping body 41 is provided with a workpiece clamping recess 411 and at least one clamping hole 412 penetrating its side wall and communicating with the workpiece clamping recess 411. Each clamping member 42 includes a connecting rod 421, which is slidably assembled in the clamping hole 412; an extruding member 422, which is connected to one end of the connecting rod 421 and is arranged on the outer side of the side wall of the clamping body 41; a clamping claw 423, which is connected to the other end of the connecting rod 421 and is arranged in the workpiece clamping recess 411 for clamping the workpiece; and a clamping reset elastic member 424 (for example: spring, rubber, etc.), which is sleeved on the connecting rod 421 between the clamping body 41 and the extruding member 422, and is used to provide a reset elastic force for the extruding member 422. The clamping claw 423 is detachably fixedly connected to the connecting rod 421, so that the operator can quickly replace the clamping claw 423 of different shapes and sizes according to actual processing requirements, so as to adapt and clamp cemented carbide workpieces of various shapes and sizes, such as round, triangular, quadrilateral, diamond and other cemented carbide cutting blades of different shapes and sizes. The pushing member 43 is fixedly mounted on the base top surface 21 of the base 2. The extrusion member 422 is provided with an extrusion inclined surface 4221, and the pushing member 43 can contact the extrusion inclined surface 4221 of the extrusion member 422, and drive the clamping member 42 by pushing the extrusion inclined surface 4221. When the driving component 3 drives the operating platform 1 to descend, the pushing member 43 contacts the extruding member 422 and applies a thrust to it, and the thrust is transmitted through the connecting rod 421, so that the clamping claw 423 moves toward the center direction of the workpiece clamping recess 411 and is in close contact with the workpiece in the workpiece clamping recess 411, thereby clamping and fixing the workpiece; when the driving component 3 drives the operating platform 1 to rise, the pushing member 43 separates from the extruding member 422, and the reset force of the clamping reset elastic member 424 pushes the extruding member 422 to move in the opposite direction, and drives the clamping claw 423 away from the center of the workpiece clamping recess 411 through the connecting rod 421, so that the clamping claw 423 is out of contact with the workpiece in the workpiece clamping recess 411, thereby releasing the workpiece.

[0054] like Figure 2 and 4 As shown, in order to further enhance the clamping and fixing effect, in the first embodiment of the present invention, preferably, two mutually symmetrical clamping holes 412 are provided on the clamping body 41, and the clamping assembly 4 also includes two clamping members 42 and two pushing members 43, and the connecting rod 421 of each clamping member 42 is constructed to be able to slide in the corresponding clamping hole 412, and the two pushing members 43 can respectively drive their respective corresponding clamping members 42 to move the clamping claws 423 toward the center direction of the workpiece clamping recess 411, thereby achieving firm clamping of both sides of the workpiece.

[0055] like Figure 5 and 6 As shown, the driving assembly 3 includes a lifting cylinder 31, a lifting guide member 32 and a lifting reset elastic member 33 (such as a spring, rubber, etc.). The lifting cylinder 31 is fixedly mounted on the lower surface 12 of the operating platform 1, and the lifting cylinder 31 has a guide groove 311. The lifting guide member 32 is fixedly mounted on the base top surface 21 of the base 2, and the lifting guide member 32 can slide up and down in the guide groove 311. The lifting reset elastic member 33 is sleeved on the lifting guide member 32 to provide a reset elastic force for the lifting cylinder 31. A conical portion 312 is provided at one end of the lifting cylinder 31, and the conical portion 312 has an inclined portion 3121 and a step portion 3122.

[0056] like Figure 5 and 6 As shown, the present invention further includes at least one locking assembly 5, which is fixedly mounted on the base top surface 21 of the base 2 and is used to lock or release the driving assembly 3. Each locking assembly 5 includes a locking body 51, a supporting base 52 and a locking member 53; the locking body 51 is fixedly mounted on the base top surface 21 of the base 2 through the supporting base 52; the locking body 51 has a locking through hole 511 penetrating the locking body 51; the locking member 53 includes a locking push rod 531, a limiting portion 532, a locking portion 533 and a locking reset elastic member 534 (such as a spring, rubber, etc.), the locking push rod 531 is configured to be slidably assembled in the locking through hole 511, the two ends of the locking push rod 531 are respectively connected to the limiting portion 532 and the locking portion 533, and the locking reset elastic member 534 is sleeved on the locking push rod 531 located between the locking body 51 and the locking portion 533. The locking portion 533 has a pushing inclined portion 5331 and a locking step portion 5332 .

[0057] When the driving assembly 3 drives the operating platform 1 to descend, the lifting cylinder 31 descends accordingly, and the tapered portion 312 of the lifting cylinder 31 first contacts the pushing tapered portion 5331 of the locking portion 533 with the inclined portion 3121, and pushes the locking portion 533 to move toward the locking body 51; as the lifting cylinder 31 continues to descend, when the step portion 3122 of the tapered portion 312 contacts the locking step portion 5332 of the locking portion 533, the reset force of the locking reset elastic member 534 is activated, pushing the locking portion 533 to move toward the lifting cylinder 31, until the step portion 3122 and the locking step portion 5332 engage with each other, thereby locking the lifting cylinder 31 and placing the driving assembly 3 in the locking position, at which time the clamping assembly 4 installed on the operating platform 1 clamps and fixes the workpiece. In order to further enhance the locking effect, the present invention preferably includes two locking assemblies 5 in the first embodiment. The two locking components 5 are symmetrically and parallelly arranged on both sides of the driving component 3, so as to achieve stable locking of both sides of the lifting cylinder 31 and ensure the stability and reliability of the driving component 3 in the locked state.

[0058] When it is necessary to release the drive component 3, it is only necessary to apply external force to the locking portion 533 and cause it to move toward the locking body 51, so that the step portion 3122 and the locking step portion 5332 that were originally engaged with each other can be separated, and the reset force of the lifting and reset elastic member 33 is activated, pushing the lifting cylinder 31 to rise, and then driving the operating platform 1 fixedly connected thereto to rise synchronously, so that the drive component 3 is in the release position. At this time, the clamping assembly 4 installed on the operating platform 1 realizes the release of the workpiece.

[0059] The present invention provides a second embodiment of a cemented carbide surface treatment device having a fast workpiece clamping mechanism. The second embodiment is substantially the same as the first embodiment, and the difference is only that:

[0060] like Figure 8 As shown, the second embodiment also includes a workpiece transfer pallet 6, which is detachably mounted on the operating platform 1, and the workpiece transfer pallet 6 is provided with at least one workpiece bearing recess 61 for carrying the workpiece, and each workpiece bearing recess 61 is provided with at least one side channel opening 611 on the side wall, and each workpiece bearing recess 61 can match and firmly fit into the workpiece clamping recess 411 of the clamping assembly 4 corresponding thereto, and the clamping claw 423 in the clamping assembly 4 is configured to be able to slide in the side channel opening 611 corresponding thereto, so as to achieve clamping, fixing or releasing the workpiece. Preferably, there are multiple workpiece bearing recesses 61 in the clamping assembly 4 and the workpiece transfer pallet 6 to meet the processing requirements of workpieces of different batches or specifications, and the number of the workpiece bearing recesses 61 is less than or equal to the number of the clamping assemblies 4, so as to ensure that each workpiece bearing recess 61 can find the corresponding clamping assembly 4 for clamping operation.

[0061] When the present invention is used in the second embodiment, the carbide workpiece is first placed in the workpiece bearing recess 61 of the workpiece transfer tray 6, and then the workpiece transfer tray 6 is fixed on the operating platform 1, and the workpiece bearing recess 61 in the workpiece transfer tray 6 is matched and firmly embedded in the workpiece clamping recess 411 of the corresponding clamping assembly 4. Then, an external force such as human power, mechanical force or electromagnetic force is applied to the driving assembly 3 to drive the operating platform 1 to descend until the pushing member 43 contacts the extruding member 422, and the connecting rod 421 is pushed by the extruding member 422 to move the clamping claw 423 toward the center direction of the workpiece clamping recess 411, thereby clamping and fixing the carbide workpiece. At this time, the tapered portion 312 of the lifting cylinder 31 in the driving assembly 3 cooperates with the locking portion 533 of the locking member 53 in the locking assembly 5 to realize the locking function to ensure the stability of the operating platform 1. After the surface treatment of the cemented carbide workpiece, such as grinding and polishing, is completed, an external force such as human, mechanical or electromagnetic force is applied to the locking portion 533 to move it toward the locking body 51, thereby releasing the driving assembly 3, and the lifting cylinder 31 is pushed up and the operating platform 1 is driven up by the reset force of the lifting reset elastic member 33. At this time, the pushing member 43 is separated from the extrusion member 422, and the extrusion member 422 is pushed to move in the opposite direction by the reset force of the clamping reset elastic member 424, and the clamping claw 423 is driven away from the center of the workpiece clamping recess 411 through the connecting rod 421, thereby releasing the workpiece. Finally, the workpiece transfer tray 6 is disassembled and removed from the operating platform 1, and then the cemented carbide workpiece is taken out from the workpiece transfer tray 6.

[0062] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
