Description

Technical Field

[0001] This utility model relates to the technical field of clamps, and in particular to a support device for clamps. Background Technology

[0002] The support device of CNC fixture is mainly used to provide stable and reliable support for the workpiece during the machining process, prevent deformation or displacement caused by cutting force or clamping force, ensure accurate workpiece positioning and high machining accuracy, and at the same time enhance the rigidity of the overall process system, improve machining efficiency and safety.

[0003] However, in existing machining production, many die-cast products will have varying degrees of deformation, causing the products to be misaligned when clamped. This results in the final machined products having off-center holes or dimensional defects, and it is impossible to identify abnormal products. This poses a quality risk after the products leave the production workshop, which can easily lead to subsequent assembly failures and affect the customer's normal production process. Therefore, a flexible support device is needed to assist CNC fixtures in support and troubleshooting. Utility Model Content

[0006] The beneficial effects of this utility model are as follows: This application integrates a movable support component and a first sensor within the first mounting cavity of the support base. This allows the support device to adaptively abut and support products with different degrees of deformation through the movable support component, effectively compensating for differences in clamping positions and preventing products with misaligned holes or dimensional defects during processing.

Detailed Implementation

[0018] The present invention will be further described in detail below through specific embodiments.

[0019] like Figures 1-7 As shown in the figure, an embodiment of the present invention provides a support device for a clamp, comprising: The system comprises a support base 1, a movable support assembly 2, and a first sensor. The support base 1 is used to mount on the fixture table and has a first mounting cavity 11. The movable support assembly 2 is used to assist the fixture in supporting the product. The movable support assembly 2 is movably connected within the first mounting cavity 11. The first sensor is located on the side wall of the first mounting cavity 11 and is used to detect whether one end of the movable support assembly 2 is abutting or not abutting the bottom of the first mounting cavity 11. When the first sensor detects that the movable support assembly 2 is not fully abutting the bottom of the first mounting cavity 11, the product is determined to be deformed. When the first sensor detects that the movable support assembly 2 is fully abutting the bottom of the first mounting cavity 11, the product is determined to be normal.

[0020] The fixtures used in this embodiment of the utility model are mainly CNC fixtures, which are special process equipment used on CNC (computer numerical control) machine tools for precise positioning and reliable clamping of workpieces.

[0021] In this embodiment of the utility model, the fixture table is the base of the CNC fixture, and the support base 1 is installed on the fixture table to assist the fixture in clamping the product; the support base 1 has a first fixed connection hole 14 on the side that contacts the fixture table, so that the support base 1 can be fixed on the fixture table by connecting to the first fixed connection hole 14 through the first threaded connector, thereby improving the stability of the support device installation.

[0022] In this embodiment of the invention, a movable support component 2 and a first sensor are integrated into the first mounting cavity 11 of the support base 1. This allows the support device 1 to adaptively abut and support products with different degrees of deformation through the movable support component 2, effectively compensating for differences in clamping positions and preventing products with misaligned holes or dimensional defects during processing. This significantly reduces the operation time during manual clamping and improves production efficiency. Simultaneously, the first sensor can detect in real time whether one end of the movable support component 2 is fully abutting the bottom of the first mounting cavity 11, thereby automatically determining the deformation state of the product. This enables accurate identification and automatic screening of abnormal products, fundamentally preventing defective products from leaving the workshop, avoiding the risk of subsequent assembly failures, and significantly improving the stability of fixture clamping, product processing accuracy, production safety, and the product dimensional qualification rate.

[0023] In this embodiment of the invention, a movable support component 2 and a first sensor are integrated into the first mounting cavity 11 of the support base 1. This allows the support device 1 to adaptively abut and support products with different degrees of deformation through the movable support component 2, effectively compensating for differences in clamping positions and preventing products with misaligned holes or dimensional defects during processing. This significantly reduces the operation time during manual clamping and improves production efficiency. Simultaneously, the first sensor can detect in real time whether one end of the movable support component 2 is fully abutting the bottom of the first mounting cavity 11, thereby automatically determining the deformation state of the product. This enables accurate identification and automatic screening of abnormal products, fundamentally preventing defective products from leaving the workshop, avoiding the risk of subsequent assembly failures, and significantly improving clamping stability, product processing accuracy, production safety, and the product dimensional qualification rate.

[0024] It is understood that the first mounting cavity 11 is preferably a cylindrical cavity with a wear-resistant coating on its inner wall to reduce the frictional resistance of the movable support assembly 2 reciprocating within the cavity and extend the service life of the movable support assembly 2.

[0025] It is understood that in this embodiment of the present invention, the first sensor is electrically connected to the control panel of the machine tool so as to feed back the status of the movable support component 2 after the product is clamped to the control panel, thereby controlling the machine tool to start in normal condition or to issue an alarm in product deformation condition, thereby reducing the production of defective products at the source and improving the product qualification rate.

[0026] Specifically, the support base 1 is also provided with a first through hole 12 for introducing gas and a second through hole 15 for discharging gas. The first through hole 12 is located at the bottom of the support base 1, and the second through hole 15 is located on the side wall of the support base 1. The first through hole 12 is connected to the first mounting cavity 11, and the second through hole 15 is connected to the first mounting cavity 11. A first sensor is located in the second through hole 15. The movable support assembly 2 seals the first through hole 12, and the first sensor detects whether the movable support assembly 2 seals or does not seal the first through hole 12 to determine whether the product is normal or deformed.

[0027] In this embodiment of the present invention, the side of the support base 1 is further provided with a second through hole 15. The second through hole 15 connects the first mounting cavity 11 and the outside of the support base 1, and is used to discharge the gas in the first mounting cavity 11, while ensuring that the movable support assembly 2 can move relative to the support base 1. The first sensor is preferably a flow sensor, used to detect the gas flow in the first mounting cavity 11. The first sensor is installed in the second through hole 15 and detects the gas discharged from the first mounting cavity 11. After the product is clamped, the gas enters the first mounting cavity 11 from the first through hole 12. When the product is normal, the movable support assembly 2 contacts the product and abuts against the bottom of the first mounting cavity 11. Due to the movable support assembly 2's contact with the first through hole 15, the gas flows through the first through hole 12 into the first mounting cavity 11. The hole 12 is sealed, preventing gas from entering the first mounting cavity 11. The flow sensor detects no gas flow in the first mounting cavity 11 and sends feedback to the control panel, which then controls the machine tool to start production. When the product deforms, the movable support assembly 2 contacts the product and abuts against the bottom of the first mounting cavity 11. There is a large gap between the movable support assembly 2 and the bottom of the first mounting cavity 11, allowing gas to continuously enter the first mounting cavity 11 from the first through hole 12 and exit from the second through hole 15. The flow sensor detects the continuous flow of gas from the first mounting cavity 11 to the second through hole 15 and sends feedback to the control panel, which then controls the machine tool to issue an alarm, effectively reducing the production of defective products and improving the product qualification rate.

[0028] Furthermore, the movable support assembly 2 includes a movable support member 21 for supporting the product and an elastic member 22 for resetting the movable support member 21. The elastic member 22 is sleeved on the movable support member 21, and the movable support member 21 is movably connected in the first mounting cavity 11. The movable support member 21 seals or does not seal the first through hole 12 through the elastic action of the elastic member 22.

[0029] In this embodiment of the present invention, the elastic element 22 is preferably a helical spring. The material of the helical spring is either spring steel or stainless steel. The spring coefficient of the helical spring is selected according to the weight of the product and the required detection sensitivity in order to improve the product qualification rate. In this embodiment of the utility model, the helical spring is sleeved on the outside of the movable support 21 to provide a restoring force for the movable support 21, and at the same time to buffer the impact force generated when the product abuts against the movable support 21, effectively improving the smoothness of the support device assisting the CNC fixture in clamping.

[0030] Furthermore, the support device also includes a limiting structure 4 for limiting the movable support member 21. The side of the support base 1 is also provided with a limiting hole 13, which connects to the first mounting cavity 11 and extends to the outside of the support base 1. The limiting structure 4 is movably connected in the limiting hole 13 and is used to limit the movable support member 21.

[0031] In this embodiment of the utility model, the limiting hole 13 is a threaded connection hole, and the limiting structure 4 is a threaded pin with a flat end. It is connected to the threaded connection hole through the threaded pin and limits the maximum distance of the movable support 21 from the bottom of the first mounting cavity 11, so as to avoid damage to the support seat 1 during the clamping process, thereby extending the service life of the support device.

[0032] Furthermore, the movable support member 21 has a first limiting groove 216 on its side along the length direction of the movable support member 21; the first limiting groove 216 is movably connected to the limiting structure 4 and is used to limit the movable support member 21.

[0033] In this embodiment of the present invention, the first limiting groove 216 is a straight groove with rounded ends along the length of the movable support member 21. This ensures that after the threaded pin is movably connected in the threaded connection hole and engaged in the first limiting groove 216, when the threaded pin moves along the trajectory of the first limiting groove 216 to both ends of the first limiting groove 216 during relative movement, the structural design of the two rounded ends can effectively buffer the impact force between the threaded pin and the first limiting groove 216, thereby extending the service life of the support device. At the same time, after the threaded pin is engaged in the first limiting groove 216, the limiting effect of the threaded pin on the first limiting groove 216 can effectively prevent the movable support member 21 from rotating relative to the support seat 1 during operation, thereby enhancing the support stability of the support device and improving the product qualification rate.

[0034] Furthermore, the movable support member 21 is provided with a planar abutment portion 211 for sealing the first through hole 12, and the planar abutment portion 211 abuts against the bottom of the first mounting cavity 11.

[0035] In this embodiment of the utility model, the bottom of the planar abutment portion 211 and the bottom of the first mounting cavity 11 are both designed as planar structures, and the surfaces of the bottom of the planar abutment portion 211 and the bottom of the first mounting cavity 11 are precision machined to ensure the sealing flatness between the planar abutment portion 211 and the bottom of the first mounting cavity 11, thereby enhancing the sealing performance of the movable support member 21 to the first through hole 12.

[0036] Furthermore, the movable support member 21 is provided with a first limiting part 212 for abutting against the elastic member 22; the first limiting part 212 is arranged along the length direction of the movable support member 21 and divides the movable support member 21 into a first connecting end 213 and a second connecting end 214, the second connecting end 214 is for the product to abut against; the first connecting end 213 is for the elastic member 22 to be sleeved on the outside, and the first connecting end 213 is used to seal the first through hole 12.

[0037] In this embodiment of the present invention, the first limiting part 212 is an annular boss surrounding the movable support member 21. One end of the elastic member 22 abuts against the surface of the annular boss facing the bottom of the first mounting cavity 11, so as to ensure that the movable support member 21 can squeeze the elastic member 22 to abut against the bottom of the first mounting cavity 11 or reset through the elastic force of the elastic member 22, thereby enhancing the smoothness of the support of the movable support member 21.

[0038] In this embodiment of the present invention, the first connecting end 213 is preferably designed as a cylindrical structure, and the diameter of the first connecting end 213 is smaller than the inner diameter of the elastic member 22, and the diameter of the first limiting part 212 is larger than the outer diameter of the elastic member 22, so as to ensure the smooth movement of the movable support member 21.

[0039] Furthermore, the length of the first connecting end 213 is less than the length of the elastic member 22 in its natural state, but greater than the length of the elastic member 22 in its compressed state. This ensures that the first connecting end 213 will not abut against the bottom of the first mounting cavity 11 in the natural state of the elastic member 22. In the compressed state of the elastic member 22, i.e., when all rings are fully fitted and cannot be compressed further, the first connecting end 213 can smoothly abut against the bottom of the first mounting cavity 11 for sealing. This ensures that the movable support member 21 can effectively seal the first through hole 12, thereby improving the reliability of the support device.

[0040] Furthermore, a product abutment portion 215 is provided on the side of the second connecting end 214 away from the first limiting portion 212 for abutting the product.

[0041] In this embodiment of the utility model, the product abutment part 215 and the second connecting end 214 are integrally formed to improve the wear resistance and support stability of the product abutment part 215. Furthermore, the product contact portion 215 has a contact inclined surface 2151 on the side away from the first limiting portion 212, and the angle between the contact inclined surface 2151 and the side of the product contact portion 215 facing the first limiting portion 212 is α, wherein 20° < α < 30°.

[0042] In this embodiment of the present invention, the angle α between the abutting inclined surface 2151 and the side of the product abutting part 215 facing the first limiting part 212 is preferably 25°. An angle of 25° allows the abutting inclined surface 2151 to achieve the best balance between providing sufficient lateral support force and avoiding excessive lateral force on the product. At the same time, an angle of 25° can play a good guiding role for the product, making it easier for the product to slide in and be positioned, playing a preliminary guiding role, and helping to enhance the support stability of the support device.

[0043] Understandably, the area of ​​the abutting inclined surface 2151 is larger than the cross-sectional area of ​​the second connecting end 214 in order to provide a more stable support surface.

[0044] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
