[0004] The embodiment of the present application provides a clamping mechanism for clamping a tool, comprising:

[0005] case;

[0006] A clamping member, movably disposed in the housing along the axial direction of the housing, and used for clamping the tool;

[0007] An elastic member, movably disposed in the housing along the axial direction of the housing and abutting against the clamping member;

[0008] An adjusting component is arranged in the shell and abuts against an end of the elastic member away from the clamping member, and the adjusting component is used to adjust the length of the elastic member in a natural state.

[0009] In some embodiments, the adjustment assembly includes an oblique pin, a push member and an adjustment member. The oblique pin is movably arranged in the shell along the axial direction of the shell and abuts against an end of the elastic member away from the clamping member. The oblique pin is movably arranged in the shell along the radial direction of the shell and abuts against the inclined surface of the oblique pin. The adjustment member is rotated radially along the shell and is passed through the shell and the push member. The push member is moved radially along the shell by rotating the adjusting member. The push member abuts against the inclined surface of the oblique pin to move the oblique pin along the axial direction of the shell, thereby adjusting the length of the elastic member under a natural condition.

[0010] In some embodiments, the number of the push members is two, and the two push members are arranged on opposite sides of the oblique pin member along the radial direction of the shell and both are in abutment with the inclined surface of the oblique pin member. The adjusting member is rotatably passed through the two push members and movably passed through the oblique pin member. The two push members are moved closer to or away from each other by rotating the adjusting member, and the two push members are in abutment with the inclined surface of the oblique pin member to make the oblique pin member move along the axial direction of the shell.

[0011] In some embodiments, the adjusting member is a positive and negative threaded screw.

[0012] In some embodiments, the adjustment assembly also includes a clamping member and a fastener, wherein the clamping member is movably disposed in the shell along the radial direction of the shell and is located on one side of the oblique pin member, the clamping member is located below the push member, and the fastener is rotatably disposed in the shell along the radial direction of the shell to be connected to the clamping member, and the fastener is used to make the clamping member press against the oblique pin member.

[0013] In some embodiments, the clamping mechanism further includes a fixing member, which is passed through the shell and rotatably passed through the clamping member to be tightly pressed against the tool in the clamping member, and the fixing member fixes and clamps the tool in the clamping member.

[0014] In some embodiments, the clamping mechanism also includes a limiting member, the shell is provided with a limiting hole, the limiting hole has an upper hole wall and a lower hole wall opposite to each other along the axial direction of the shell, the limiting member is passed through the limiting hole and is connected to the clamping member, and the limiting member is used to abut against the upper hole wall and the lower hole wall to limit the clamping member when the clamping member moves along the axial direction of the shell.

[0015] In some embodiments, the lower hole wall is provided with multiple steps.

[0016] In some embodiments, the clamping mechanism further includes a connecting member, which is connected to the shell and is used to connect to an external tool handle.

[0052] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0053] See also Figure 1 The embodiment of the present application provides a clamping mechanism 100. The clamping mechanism 100 is used to clamp a tool 200, so that the tool 200 can be pressed adaptively against the product for processing when processing a product (not shown), and then the tool 200 can perform contour processing according to the shape of the product to achieve the effect of uniformly processing the product, wherein the tool 200 can chamfer the product to achieve the effect of chamfering and deburring, thereby improving the processing yield of the product.

[0054] Please refer to Figure 2 , Figure 3 and Figure 4 The clamping mechanism 100 includes a housing 10, a clamping member 20, an elastic member 30 and an adjustment assembly 40. For ease of understanding and description, the present embodiment is defined as follows Figure 1 The Z-axis direction shown is the axial direction of the housing 10, and can also be understood as the axial direction of the clamping mechanism 100. Figure 1 The X-axis direction and the Y-axis direction shown can both be radial directions of the shell 10, and can also be understood as radial directions of the clamping mechanism 100. It can be understood that the radial directions of the shell 10 or the clamping mechanism 100 can also be any other directions in the XY plane.

[0055] The housing 10 is provided with an assembly hole 11, which penetrates the housing 10 in the axial direction of the housing 10. The clamping member 20 is movably disposed in the assembly hole 11 of the housing 10 in the axial direction of the housing 10, and the clamping member 20 is used to clamp the tool 200. The elastic member 30 is movably disposed in the assembly hole 11 of the housing 10 in the axial direction of the housing 10 and abuts against the clamping member 20. The elastic member 30 can be a spring, and it can be understood that the elastic member 30 extends in the axial direction of the housing 10. The adjustment component 40 is disposed in the assembly hole 11 of the housing 10 and abuts against one end of the elastic member 30 away from the clamping member 20. The adjustment component 40 is used to adjust the length of the elastic member 30 in the natural state, thereby adjusting the pressure applied by the elastic member 30 to the clamping member 20 and the tool 200, and further adjusting the pressure applied by the tool 200 to the product. The "length of the elastic member 30 in a natural state" can be understood as the length of the elastic member 30 between the adjustment assembly 40 and the clamping member 20 after the clamping mechanism 100 clamps the tool 200 and before the tool 200 processes the product, when the elastic member 30 is in a compressed state due to the restriction of the clamping member 20 and the adjustment assembly 40. It can be understood that the assembly hole 11 can be adaptively assembled with objects or components such as the clamping member 20, the elastic member 30, and the adjustment assembly 40.

[0056] When the clamping mechanism 100 is in use, the length of the elastic member 30 is adjusted in a natural state according to the pressure required by the product to be processed. After the length of the elastic member 30 is adjusted, the tool 200 is clamped in the clamping member 20, and the clamping mechanism 100 and the tool 200 are driven by the external tool handle (not shown) and the external spindle (not shown) to process the product. Since the clamping member 20 is movably arranged in the assembly hole 11 of the housing 10 and abuts against the elastic member 30, when the tool 200 abuts against the product, the tool 200 is subjected to the reaction force of the product and carries The dynamic clamp 20 compresses the elastic member 30, and the elastic member 30 is compressed by the clamp 20 to generate a greater elastic force, so that the elastic member 30 can reversely provide pressure to the clamp 20, so that the tool 200 can adaptively pressurize the product under the elastic force of the elastic member 30 for processing. Since the tool 200 is always pressurized against the product for processing, the tool 200 can perform contour processing according to the shape of the product to achieve the effect of uniformly processing the product and the effect of chamfering to remove burrs, which is beneficial to improve the processing yield of the product. In addition, when the material of the processed product changes and the required processing pressure changes, the length of the elastic member 30 under the natural condition is adjusted by adjusting the component 40, that is, adjusting the initial pressure applied by the elastic member 30 to the clamp 20, so that the tool 200 can adaptively pressurize the product according to the pressure required by the product under the elastic force of the elastic member 30, so as to achieve the effect of uniformly processing the product and improve the processing yield of the product. The clamping mechanism 100 has a wide range of uses, a simple structure, and low cost.

[0057] In the embodiment of the present application, the adjustment assembly 40 includes an inclined pin 41, a push member 42 and an adjustment member 43. The inclined pin 41 is movably disposed in the assembly hole 11 of the housing 10 along the axial direction of the housing 10 and abuts against one end of the elastic member 30 away from the clamping member 20. The inclined pin 41 is movably disposed in the assembly hole 11 of the housing 10 along the radial direction of the housing 10 and abuts against the inclined surface of the inclined pin 41. The adjustment member 43 is rotatably disposed in the housing 10 and the push member 42 along the radial direction of the housing 10. The push member 42 is moved radially along the housing 10 by rotating the adjustment member 43. The push member 42 abuts against the inclined surface of the inclined pin 41 to move the inclined pin 41 along the axial direction of the housing 10, so that the inclined pin 41 is moved away from or close to the clamping member 20, thereby adjusting the length of the elastic member 30 between the clamping member 20 and the inclined pin 41 under natural conditions. In this way, by setting the specific structure of the above-mentioned adjustment component 40, the length of the elastic component 30 under natural conditions can be adjusted by rotating the adjustment member 43. The adjustment component 40 converts the radial force into the axial force. The adjustment component 40 has a simple structure and a simple operation method.

[0058] Furthermore, the number of the push members 42 can be two, and the two push members 42 are arranged on opposite sides of the oblique pin member 41 along the radial direction of the housing 10 and are both matched and abutted with the inclined surface of the oblique pin member 41, and the adjusting member 43 is rotatably penetrated in the two push members 42 and movably penetrated in the oblique pin member 41, wherein the oblique pin member 41 is provided with an avoidance groove 411, and the adjusting member 43 is penetrated in the avoidance groove 411 to achieve penetration in the oblique pin member 41, and the extension direction of the adjusting member 43 is substantially perpendicular to the extension direction of the oblique pin member 41. By rotating the adjusting member 43 to make the two push members 42 approach or move away from each other, the two push members 42 are matched and abutted with the inclined surface of the oblique pin member 41 respectively, so that the oblique pin member 41 moves along the axial direction of the housing 10. In this way, by setting the number of the push members 42 to two, the stability of the oblique pin member 41 when moving along the axial direction of the housing 10 is guaranteed, and the deflection of the oblique pin member 41 is avoided.

[0059] Furthermore, the adjusting member 43 may be a positive and negative threaded rod. Thus, by limiting the adjusting member 43 to be a positive and negative threaded rod, the two push members 42 can move closer to or farther from each other when the adjusting member 43 rotates. The adjusting assembly 40 has a simple structure and low cost.

[0060] Further, the adjustment assembly 40 may also include a clamping member 44 and a fastener 45. The clamping member 44 is movably disposed in the radial direction of the housing 10 in the assembly hole 11 of the housing 10 and is located on one side of the oblique pin 41. The clamping member 44 is located below the push member 42. The fastener 45 may be a screw. The fastener 45 is rotatably disposed in the radial direction of the housing 10 and is connected to the clamping member 44. The fastener 45 is used to make the clamping member 44 press against the oblique pin 41. Specifically, the number of the clamping members 44 and the fastener 45 are both two and one-to-one corresponding. The two clamping members 44 are movably disposed in the radial direction of the housing 10 on the opposite sides of the oblique pin 41 and are one-to-one corresponding to the two push members 42. Each clamping member 44 is located below the corresponding push member 42. Each fastener 45 is rotatably disposed in the radial direction of the housing 10 and is connected to the corresponding clamping member 44. In this way, by setting the above-mentioned clamping member 44 and fastener 45, after adjusting the length of the elastic member 30 by means of the adjusting member 43, the push member 42 and the inclined pin member 41, the two fasteners 45 can be rotated so that the two clamping members 44 clamp the inclined pin member 41 to prevent the inclined pin member 41 from moving axially, thereby ensuring that the length of the elastic member 30 remains unchanged after adjustment by the adjusting assembly 40, thereby improving the adjustment accuracy of the adjusting assembly 40.

[0061] It can be understood that in other embodiments, the adjustment component 40 can also be other functional components or objects that can adjust the length of the elastic member 30. For example, the adjustment component 40 can be a screw, which is rotated from the upper end of the housing 10 and penetrated into the housing 10 to extend into the assembly hole 11 of the housing 10 and abut against the elastic member 30. The length of the elastic member 30 in a natural state is adjusted by screwing the screw in or out relative to the assembly hole 11. For another example, the adjustment component 40 may include a rotating shaft and an eccentric wheel. The rotating shaft is rotatably arranged on the housing 10 along the radial direction of the housing 10, and the eccentric wheel is sleeved on the rotating shaft and is located in the assembly hole 11 of the housing 10 and abuts against the elastic member 30. The rotating shaft drives the eccentric wheel to rotate, so that the eccentric wheel adjusts the length of the elastic member 30 in a natural state through eccentric action.

[0062] In the embodiment of the present application, the clamping mechanism 100 may further include a fixing member 50, which is inserted through the housing 10 and rotated to be inserted through the clamping member 20 to be tightly pressed against the tool 200 in the clamping member 20, and the fixing member 50 is used to fix the tool 200 in the clamping member 20. Specifically, the housing 10 is provided with a fixing hole 12, and the fixing hole 12 is connected to the assembly hole 11. The fixing member 50 is inserted through the fixing hole 12 to be inserted into the housing 10, and the number of the fixing members 50 may be two. In this way, by providing the above-mentioned fixing member 50, the tool 200 is fixedly clamped in the clamping member 20. By providing the fixing hole 12, the fixing member 50 can be inserted into the housing 10, and an operating space is reserved for operating the fixing member 50. It can be understood that in other embodiments, the number of the fixing members 50 can be more.

[0063] In the embodiment of the present application, the clamping mechanism 100 may further include a limiter 60. The housing 10 is provided with a limiter hole 13. The limiter hole 13 is connected to the assembly hole 11. The limiter hole 13 has an upper hole wall 131 and a lower hole wall 132 that are opposite to each other along the axial direction of the housing 10. The limiter 60 is passed through the limiter hole 13 and connected to the clamping member 20. The limiter 60 moves synchronously with the clamping member 20. The limiter 60 is used to abut against the upper hole wall 131 and the lower hole wall 132 when the clamping member 20 moves along the axial direction of the housing 10 to limit the clamping member 20. In this way, by setting the above-mentioned limiter 60 and the limiter hole 13, the clamping member 20 is limited, thereby limiting the tool 200, and preventing the tool 200 from being driven away from the housing 10 by the reaction force of the product. Among them, the limiter 60 can be a screw.

[0064] Furthermore, the lower hole wall 132 of the limiting hole 13 is provided with multiple steps, wherein the multiple steps can be arranged regularly or irregularly, can be arranged along one side, or can be arranged on both sides, and the steps of the lower hole wall 132 of the limiting hole 13 are used to receive the limiting member 60 to adjust the length of the elastic member 30 under natural conditions. In this way, by arranging multiple steps on the lower hole wall 132 of the limiting hole 13, the length of the elastic member 30 under natural conditions can be adjusted, and the length adjustment range of the elastic member 30 is large and the adjustment method is simple; the length adjustment of the elastic member 30 under natural conditions by the multiple steps is coordinated with the length adjustment of the elastic member 30 under natural conditions by the adjustment component 40, so that the range of the adjustable length of the elastic member 30 becomes larger and finer, so that the range of the pressure applied to the product by the tool 200 is larger and finer, which is conducive to improving the product processing yield.

[0065] Furthermore, the housing 10 is also provided with a balancing hole 14, which is located below the limiting hole 13, and the balancing hole 14 and the limiting hole 13 are located on the same side of the housing 10, and the fixing hole 12 is located on the other side of the housing 10. In this way, by providing the above-mentioned balancing hole 14, the housing 10 is kept relatively balanced, and the stability of the housing 10 during rotation is ensured. It can be understood that in other embodiments, when the limiting hole 13 and the fixing hole 12 can keep the housing 10 relatively balanced, the balancing hole 14 can also be omitted. Alternatively, the balancing hole 14 can also be provided at other positions of the housing 10 so that the housing 10 can maintain relative balance, and the embodiments of the present application do not specifically limit this.

[0066] In the embodiment of the present application, the clamping mechanism 100 further includes a connecting member 70, which is connected to the housing 10 and is used to connect to an external tool handle. Specifically, a positioning portion 15 is convexly provided at one end of the housing 10 facing the connecting member 70, and the number of the positioning portions 15 is four, and the four positioning portions 15 are used to fit and insert into the connecting member 70 so that the connecting member 70 and the housing 10 can be accurately connected. In this way, by providing the above-mentioned connecting member 70, the clamping mechanism 100 can be connected to an external tool handle.

[0067] The clamping mechanism 100 provided in the embodiment of the present application cooperates with the shell 10, the clamping part 20, the elastic part 30 and the adjustment assembly 40. When the tool 200 abuts against the product, the tool 200 is subjected to a reaction force and drives the clamping part 20 to compress the elastic part 30. The elastic part 30 is compressed to generate elastic force, so that the elastic part 30 can provide pressure to the clamping part 20 in reverse, so that the tool 200 can adaptively apply pressure to the product for processing. The tool 200 can perform contour processing according to the shape of the product to achieve the effect of removing burrs and uniformly processing the product, which is beneficial to improving the product processing yield. In addition, when the materials of the processed products are different, the tool 200 needs to use different pressures to process the products. For example, when the processed material is metal, the required pressure is higher, and when the processed material is plastic, the required pressure is lower. The length of the elastic part 30 under natural conditions is adjusted by adjusting the adjustment component 40, that is, adjusting the initial pressure applied by the elastic part 30 to the clamping part 20, so that the tool 200 can adaptively pressurize the product according to the pressure required by the product, so as to achieve the effect of uniformly processing the product and improve the product processing yield.

[0068] The clamping mechanism 100 provided in the embodiment of the present application further enables the tool 200 to be fixedly clamped in the clamping member 20 through the cooperation of the fixing member 50 .

[0069] The clamping mechanism 100 provided in the embodiment of the present application further achieves the limitation of the tool 200 through the cooperation of the limiting member 60 and the limiting hole 13, and through the multiple steps of the lower hole wall 132 of the limiting hole 13, the range in which the length of the elastic member 30 can be adjusted is enlarged and refined, thereby making the range of the pressure applied by the tool 200 to the product larger and more refined, which is beneficial to improving the product processing yield.

[0070] The clamping mechanism 100 provided in the embodiment of the present application is further connected to an external tool handle through the cooperation of the connecting piece 70.

[0071] The embodiment of the present application also provides an adaptive processing device (not shown). The adaptive processing device is used to clamp the tool 200, so that the tool 200 can be adaptively pressed against the product for processing according to the processing pressure required by the product when processing the product, so that the tool 200 can perform contour processing according to the shape of the product to achieve the effect of uniformly processing the product. The adaptive processing device includes a tool handle, a clamping mechanism 100 and a tool 200 as described in the above technical solution. The tool handle is used to connect to an external spindle, and the housing 10 of the clamping mechanism 100 is connected to the tool handle through a connecting member 70, and the tool 200 is clamped in the clamping member 20 of the clamping mechanism 100.

[0072] When the above-mentioned adaptive processing device is used, the tool handle is connected to the external spindle, and the length of the elastic member 30 under the natural condition is adjusted according to the pressure required by the product to be processed. After adjusting the length of the elastic member 30, the tool 200 is clamped in the clamping member 20, and the tool handle, the clamping mechanism 100 and the tool 200 are driven by the external spindle to process the product. Since the clamping member 20 is movably arranged in the assembly hole 11 of the housing 10 and abuts against the elastic member 30, when the tool 200 abuts against the product, the tool 200 is subjected to the reaction force of the product and carries The movable clamp 20 compresses the elastic member 30, and the elastic member 30 is compressed by the clamp 20 to generate a greater elastic force, so that the elastic member 30 can reversely provide pressure to the clamp 20, so that the tool 200 can adaptively pressurize the product under the elastic force of the elastic member 30 for processing. Since the tool 200 is always pressurized against the product for processing, the tool 200 can perform contour processing according to the shape of the product to achieve the effect of uniformly processing the product and the effect of chamfering to remove burrs, which is beneficial to improve the processing yield of the product. In addition, when the material of the processed product changes, the length of the elastic member 30 under the natural state is adjusted by adjusting the component 40 and at least one of the multiple steps, that is, adjusting the initial pressure applied by the elastic member 30 to the clamp 20, so that the tool 200 can adaptively pressurize the product according to the pressure required by the product under the elastic force of the elastic member 30, so as to achieve the effect of uniformly processing the product and improve the processing yield of the product. The adaptive processing device has a wide range of uses, a simple structure, and low cost.
