Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0058] See also Figure 1 , Figure 2 and Figure 3 The embodiment of the present application provides an extrusion support device 100 for extruding or supporting a product. The extrusion support device 100 of the embodiment of the present application includes a housing 10, a driving member 20, a bearing seat 30, a pusher head 40, a sliding assembly 50 and an elastic member 60.

[0059] The driving member 20 is disposed in the housing 10, and has a movable output shaft 21. The driving member 20 may be a through-type motor, so that the output shaft 21 can move more accurately and stably. Of course, in some other embodiments, the driving member 20 may also be an electric push rod, a pneumatic push rod, etc., which is not specifically limited in the embodiments of the present application.

[0060] The bearing seat 30 is disposed on the driving member 20 and is located in the housing 10 . The bearing seat 30 defines a sliding hole 31 . The extending direction of the sliding hole 31 is the same as the moving direction of the output shaft 21 . The output shaft 21 extends into the sliding hole 31 .

[0061] The pusher head 40 is slidably disposed on the housing 10 along the moving direction of the output shaft 21 and is disposed opposite to the supporting base 30 .

[0062] The sliding assembly 50 is slidably disposed in the sliding hole 31 and connected to the output shaft 21 . The sliding assembly 50 slides along the extending direction of the sliding hole 31 driven by the output shaft 21 .

[0063] The elastic member 60 may be a spring, and both ends of the elastic member 60 are respectively connected to the sliding assembly 50 and the push head 40 . Driven by the sliding assembly 50 , the elastic member 60 elastically drives the push head 40 away from the driving member 20 to squeeze or support the product.

[0064] When the extrusion support device 100 of the embodiment of the present application extrudes or supports a product, the output shaft 21 of the driving member 20 drives the sliding assembly 50 to move toward the elastic member 60 and compress the elastic member 60, and the elastic member 60 drives the push head 40 away from the driving member 20 to apply a force to the product, thereby extruding or supporting the product. Since the moving distance of the output shaft 21 of the driving member 20 can be accurately controlled, the compression amount of the elastic member 60 by the sliding assembly 50 can be accurately controlled, and then the magnitude of the force driven by the elastic member 60 to drive the push head 40 to apply to the product can be accurately controlled, and the risk of damaging the product can be reduced.

[0065] In this embodiment, the housing 10 includes a housing 11, a first flange cover 12, and a second flange cover 13. The housing 11 is provided with a receiving hole 111; the first flange cover 12 is provided at one end of the housing 11 and closes the receiving hole 111; the driving member 20 is provided at the receiving hole 111 and connected to the first flange cover 12; the bearing seat 30 is provided at a side of the driving member 20 away from the first flange cover 12; the second flange cover 13 is provided at the other end of the housing 11 and closes the receiving hole 111; the second flange cover 13 is provided with an insertion hole 131 connected to the receiving hole 111; the push head 40 slides through the insertion hole 131 and extends into the receiving hole 111 and is arranged opposite to the bearing seat 30. In this way, it is convenient to disassemble and assemble the driving member 20 and the push head 40.

[0066] In this embodiment, when the extrusion support device 100 is used to extrude or support a product, different elastic members 60 can be selected according to the structure of the product, so that the extrusion support device 100 can meet the extrusion or support requirements of different products. When a different elastic member 60 needs to be replaced, the second flange cover 13 can be opened to replace the corresponding elastic member 60, which is conducive to improving the convenience of replacing the elastic member 60.

[0067] In this embodiment, a moving groove 41 is provided at one end of the push head 40 close to the bearing seat 30, and the extending direction of the moving groove 41 is the same as the moving direction of the output shaft 21. One end of the bearing seat 30 close to the push head 40 extends into the moving groove 41, and a circumferential side wall of the bearing seat 30 close to the push head 40 is convexly provided with a limiting convex ring 33 that slides and abuts against the groove wall of the moving groove 41. The extrusion support device 100 also includes a limiting member 70, which is inserted into the push head 40 and extends into the moving groove 41, and one end of the limiting member 70 extending into the moving groove 41 is located at a side of the limiting convex ring 33 close to the driving member 20. When the elastic member 60 elastically drives the push head 40 away from the driving member 20, the limiting member 70 abuts against the limiting convex ring 33 to limit the moving distance of the push head 40. The limiting member 70 may be a pin. By providing a movable groove 41 on the push head 40 and making the limiting convex ring 33 slide and abut against the groove wall of the movable groove 41, the limiting convex ring 33 can support the push head 40 when the push head 40 moves, which is beneficial to improve the stability of the force applied by the push head 40 to the product. By setting a limiting member 70 to cooperate with the limiting convex ring 33 to limit the moving distance of the push head 40 driven by the elastic member 60, the maximum stroke of the push head 40 can be controlled, thereby controlling the range of force applied by the push head 40 to the product, which is beneficial to reduce the risk of damaging the product.

[0068] Please refer to Figure 4 In this embodiment, a plurality of gaps 34 are provided on the limiting convex ring 33, and the plurality of gaps 34 are connected to the moving groove 41, and the plurality of gaps 34 are used to discharge the gas in the moving groove 41. Thus, it is possible to effectively avoid the pressure difference between the air pressure in the moving groove 41 and the external air pressure, which may affect the accuracy of the force applied by the push head 40 to the product.

[0069] In this embodiment, there can be multiple limit members 70, and the number of limit members 70 is the same as the number of notches 34. Multiple limit members 70 are inserted into the push head 40 at intervals along the circumference of the push head 40 and extend into the moving groove 41, and multiple limit members 70 correspond to multiple notches 34 one by one. When installing the push head 40, multiple limit members 70 can be moved to the side of the limit convex ring 33 close to the driving member 20 through the corresponding notches 34, and then the push head 40 is rotated to make the multiple limit members 70 misaligned with the corresponding notches 34. When disassembling the push head 40, the push head 40 is rotated to make the multiple limit members 70 face the corresponding notches 34, and then the push head 40 is pulled out. In this way, it is convenient to disassemble and assemble the push head 40.

[0070] See also Figure 1 and Figure 2In this embodiment, a plurality of vent holes 42 are provided at one end of the push head 40 away from the driving member 20, and the vent holes 42 are used to discharge the gas in the moving groove 41, thereby further reducing the resistance to the push head 40 caused by the pressure difference between the air pressure in the moving groove 41 and the external air pressure when the push head 40 moves, which is beneficial to improve the accuracy of the force applied by the push head 40 to the product.

[0071] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the wall of the sliding hole 31 is provided with a guide groove 32, and the extension direction of the guide groove 32 is the same as the extension direction of the sliding hole 31. The sliding assembly 50 includes a first sliding member 51 and a second sliding member 52; the first sliding member 51 is slidably disposed in the sliding hole 31 and connected to the output shaft 21, and the side wall of the first sliding member 51 is convexly provided with a first guide protrusion 511 that slidably cooperates with the guide groove 32; the second sliding member 52 is slidably disposed in the sliding hole 31, and the two ends of the second sliding member 52 are respectively abutted against the first sliding member 51 and the elastic member 60. In this way, when the output shaft 21 drives the first sliding member 51 and the second sliding member 52 to slide, the cooperation between the guide groove 32 and the first guide protrusion 511 can limit the rotation of the first sliding member 51 when sliding, thereby reducing the thrust loss of the output shaft 21, and is conducive to improving the accuracy of the output shaft 21 driving the push head 40 to apply force to the product through the sliding assembly 50 and the elastic member 60.

[0072] In the present embodiment, since the driving member 20 is a through-type motor, the self-rotation of the output shaft 21 is the source power. When the output shaft 21 encounters resistance, the nut (not shown) built into the through-type motor converts the self-rotation of the output shaft 21 into forward movement and forms a thrust, thereby causing the first sliding member 51 and the second sliding member 52 to slide. By setting the guide groove 32 and the first guide protrusion 511 to cooperate with each other to limit the rotation of the first sliding member 51 when sliding, the output shaft 21 can be limited to drive the first sliding member 51 and the second sliding member 52 to slide and self-rotate, thereby reducing the thrust loss of the output shaft 21.

[0073] In some other embodiments, when the driving member 20 is an electric push rod, a pneumatic push rod or other power parts, the output shaft 21 may also shake. By setting a guide groove 32 and a first guide protrusion 511 to cooperate with each other to limit the rotation of the first sliding member 51 when sliding, it is also possible to effectively limit the output shaft 21 from shaking when driving the first sliding member 51 and the second sliding member 52 to slide, thereby reducing the thrust loss of the output shaft 21.

[0074] In this embodiment, the first guide protrusion 511 is further provided with a second guide protrusion 512 that is slidably abutted against the bottom of the guide groove 32. The second guide protrusion 512 can reduce the contact area between the first guide protrusion 511 and the guide groove 32, thereby reducing the friction between the first guide protrusion 511 and the guide groove 32, and further reducing the thrust loss of the first sliding member 51. In addition, the second guide protrusion 512 cooperates with the first guide protrusion 511 to form a three-point contact with the guide groove 32, and the three-point contact has stability, thereby effectively limiting the rotation of the first sliding member 51 when sliding.

[0075] In this embodiment, a convex abutting ring 521 is convexly provided on the peripheral side wall of one end of the second sliding member 52 away from the first sliding member 51. The second sliding member 52 may be cylindrical. The convex abutting ring 521 extends along the radial direction of the second sliding member 52. The convex abutting ring 521 is located on the side of the bearing seat 30 away from the driving member 20. The convex abutting ring 521 is used to abut against the side of the bearing seat 30 away from the driving member 20 to limit the distance that the first sliding member 51 moves into the sliding hole 31. Since the second sliding member 52 abuts against the elastic member 60, when the output shaft 21 drives the first sliding member 51 to reset, the elastic member 60 drives the second sliding member 52 to return. By setting the convex abutting ring 521 to limit the distance that the first sliding member 51 moves into the sliding hole 31, it is beneficial to improve the accuracy of the return of the second sliding member 52 and to improve the accuracy of the force applied by the extrusion support device 100 when extruding or supporting the product again.

[0076] See also Figure 2 and Figure 3 In this embodiment, the extrusion support device 100 further includes a guide rod 80, one end of which is connected to the push head 40, the other end of which is slidably inserted into the sliding assembly 50, and the elastic member 60 is sleeved on the guide rod 80. Specifically, the second sliding member 52 is provided with a through hole 522, the extension direction of the through hole 522 is the same as the extension direction of the sliding hole 31, the guide rod 80 is located in the moving groove 41 and one end of the guide rod 80 is connected to the groove bottom of the moving groove 41, and the other end of the guide rod 80 is slidably inserted into the through hole 522. When the elastic member 60 drives the push head 40 to move under the drive of the sliding assembly 50, the guide rod 80 can guide the extension direction of the elastic member 60 and prevent the elastic member 60 from bending when it is extended, thereby facilitating the improvement of the accuracy of the elastic member 60 driving the push head 40 to apply force to the product.

[0077] See also Figure 1 , Figure 2 and Figure 3In this embodiment, the extrusion support device 100 further includes a mounting seat 91 and a sensing member 92. The mounting seat 91 is disposed on the housing 10 and is located on the side of the driving member 20 away from the sliding assembly 50. The mounting seat 91 is provided with a sensing hole 911. The end of the output shaft 21 away from the sliding assembly 50 extends out of the housing 10 and extends into the sensing hole 911. The sensing member 92 is disposed on the mounting seat 91 and is arranged opposite to the output shaft 21. The sensing member 92 is used to sense the moving distance of the output shaft 21. Specifically, the mounting seat 91 is disposed on the side of the first flange cover 12 away from the receiving hole 111. The second flange cover 13 is provided with a protruding hole 121 which is connected with the receiving hole 111 and the sensing hole 911 at both ends. The end of the output shaft 21 away from the sliding assembly 50 passes through the protruding hole 121 and extends into the sensing hole 911. By providing the induction member 92 to sense the moving distance of the output shaft 21 , it is convenient to control the stroke of the output shaft 21 , thereby facilitating improving the accuracy of the output shaft 21 driving the push head 40 to apply force to the product through the sliding assembly 50 and the elastic member 60 .

[0078] In this embodiment, the extrusion support device 100 also includes a controller (not shown), which is electrically connected to the sensing member 92 and the driving member 20 respectively. The controller controls the travel of the output shaft 21 driven by the driving member 20 according to the moving distance of the output shaft 21 sensed by the sensing member 92, thereby facilitating the control of the push head 40 to apply different forces to the product according to different products.

[0079] In some other embodiments, the controller may also be a part of the driving member 20, which is not specifically limited in the embodiments of the present application.

[0080] In this embodiment, the sensing member 92 is a magnetic sensor, and the extrusion support device 100 also includes a magnetic component 93. The magnetic component 93 is arranged at one end of the output shaft 21 away from the sliding component 50 and is slidably arranged in the sensing hole 911. The sensing member 92 obtains the moving distance of the output shaft 21 by sensing the moving distance of the magnetic component 93. This is beneficial to improving the accuracy of the sensing member 92 in sensing the moving distance of the output shaft 21.

[0081] In this embodiment, the magnetic component 93 includes a fixed block 931 and a magnetic ring 932. The fixed block 931 is detachably arranged at one end of the output shaft 21 away from the sliding component 50 and is slidably arranged in the sensing hole 911. The magnetic ring 932 is sleeved on the fixed block 931. The sensing element 92 obtains the moving distance of the output shaft 21 by sensing the moving distance of the magnetic ring 932, which is beneficial to improve the accuracy of the sensing element 92 sensing the moving distance of the output shaft 21.

[0082] In summary, when the extrusion support device 100 of the embodiment of the present application extrudes or supports the product, the output shaft 21 of the driving member 20 drives the sliding assembly 50 to move toward the elastic member 60 and compress the elastic member 60, and the elastic member 60 elastically drives the push head 40 away from the driving member 20 to apply a force to the product, thereby extruding or supporting the product. Since the moving distance of the output shaft 21 of the driving member 20 can be accurately controlled, the compression amount of the elastic member 60 compressed by the sliding assembly 50 can be accurately controlled, and then the magnitude of the force applied to the product by the elastic member 60 driving the push head 40 can be accurately controlled, and the risk of damaging the product can be reduced. In addition, the elastic member 60 drives the push head 40 to flexibly abut against the product and slowly apply a force, thereby further reducing the risk of damaging the product. In this way, the extrusion support device 100 of the embodiment of the present application can accurately control the magnitude of the force when extruding or supporting the product, and can reduce the risk of damaging the product.
