[0024] The present invention is further described below in conjunction with embodiments and drawings.

[0025] Example 1

[0026] like Figure 1 As shown, a motorcycle shock absorber inverted bottom cylinder double-sided multi-hole synchronous floating chamfering device mainly comprises a workbench 1, on both sides of the workbench 1 are installed movable conveying bottom plates 10, on the conveying bottom plates 10 are fixed chamfering tables 2, two chamfering tables 2 are arranged opposite to each other, a workpiece fixing seat 3 is arranged between the two conveying bottom plates 10, the workpiece fixing seat 3 is installed on the workbench 1, and the outer sides of the two chamfering tables 2 are fixed with motors 4, and the output shaft 401 of the motor 4 extends into the In the chamfering table 2, at least one transmission shaft 7 is installed in the chamfering table 2, and the transmission shafts 7 are parallel to the output shaft 401. The output shaft 401 can drive the transmission shaft 7 to rotate. A connecting shaft 17 is connected to the end of the transmission shaft 7 away from the motor 4. The outer end of the connecting shaft 17 extends out of the chamfering table 2, and a chamfering tool 5 is connected to the protruding end of the connecting shaft 17 through a universal joint 18. The hole center of the workpiece barrel joint can be automatically found through the universal joint 6, so as to chamfer the hole.

[0027] like Figures 3 to 5As shown, a driving gear 15 is fixedly sleeved on the output shaft 401, and a driven gear 16 is fixedly sleeved on the transmission shaft 7. The driven gear 16 is arranged circumferentially along the driving gear 15 and meshes with the driving gear 15. The motor 4 provides power for the rotation of the driving gear 15, and the driven gear 16 meshed with it can rotate with the driving gear 15. A square connecting hole 1701 is axially opened at one end of the connecting shaft 17 close to the chamfering table 2, and a connecting piece adapted to the structure of the square connecting hole 1701 is provided at one end of the transmission shaft 7 connected to the connecting shaft 17. The connecting piece extends into the square connecting hole 1701 to achieve the connection between the transmission shaft 7 and the connecting shaft 17.

[0028] A mounting hole 1702 is axially provided at one end of the connecting shaft 17 close to the chamfering tool 5, and a universal joint fork at one end of the universal joint 18 is installed in the mounting hole 1702, and the other end extends into the chamfering tool 5. A limit member 6 is sleeved on the outside of the connection between the chamfering tool 5, the universal joint 18 and the connecting shaft 17. The limit member 6 includes a spring or a sleeve, and the tool head of the chamfering tool 5 can extend out of the limit member 6. The limit member 6 can limit the internal chamfering tool 5 to prevent it from excessively deviating on the universal joint 18, thereby assisting the chamfering tool 5 to find the center of the hole and ensure accurate positioning.

[0029] The workbench 1 is a rectangular parallelepiped structure, and two guide rails 9 are arranged in parallel along the length direction on the workbench 1. A slider 19 cooperating with the guide rail 9 is arranged at the bottom of the transmission base plate 10, and guide rail limit seats 8 are arranged at both ends of the two guide rails 9. The transmission base plate 10 can move left and right on the guide rail 9 through the slider 19, so as to realize chamfering of the middle workpiece, and the guide rail limit seats 8 arranged at both ends can prevent the transmission base plate 10 from excessive movement and sliding out of the guide rail 9, thereby realizing the limiting function.

[0030] like Figure 6 As shown, the two conveying base plates 10 are one left conveying base plate 1001 and the other right conveying base plate 1002. A telescopic cylinder assembly 20 is arranged between the left conveying base plate 1001 and the right conveying base plate 1002. One end of the cylinder body of the telescopic cylinder assembly 20 is fixed to the left conveying base plate 1001, and one end of the piston rod is fixed to the right conveying base plate 1002. The telescopic cylinder assembly 20 can automatically push the conveying base plates 10 on both sides to approach each other, thereby realizing automation and saving manpower.

[0031] A proximity switch 21 is arranged above the telescopic cylinder assembly 20, and a wire is connected to the proximity switch 21. A receiving assembly 22 is correspondingly arranged on the right conveying base plate 1002 on the opposite side. The receiving assembly 22 is close to one side of the chamfering table 2. As the telescopic cylinder assembly 20 works, the proximity switch 21 above it gradually approaches the receiving assembly 22. When the proximity switch 21 is against the receiving assembly 22, the motor 4 connected to the chamfering table 2 starts to work, and the chamfering tool 5 chamfers the workpiece. After the processing is completed, the telescopic cylinder assembly 20 drives the proximity switch 21 away from the receiving assembly 22, and the motor 4 stops working. After the conveying base plate 10 returns to the initial position, the processed workpiece is removed from the workpiece fixing seat 3.

[0032] The workpiece fixing seat 3 includes a vertically arranged fixing plate 301 and a spindle 302 arranged perpendicular to the fixing plate 301, a clamping claw 303 parallel to the spindle 302 is arranged at the top of the fixing plate 301, a mounting groove is reserved between the clamping claws 303, fixing columns are arranged on the left and right sides of the fixing plate 301, and a telescopic spring 304 is sleeved on the outer side of the fixing column. The workpiece barrel joint can be very firmly connected to the spindle 2, and its upward protruding part can just be inserted into the mounting groove between the clamping claws 14 to further fix the workpiece to avoid the workpiece falling off due to vibration during the chamfering process. The telescopic springs 304 on both sides can prevent the chamfering tools 5 on both sides from rigid collision and thus causing damage. At the same time, the telescopic springs 304 can push the conveying base plates 10 on both sides away from the middle workpiece fixing seat 3 after chamfering is completed.

[0033] Four supporting legs 13 are further provided at the bottom of the base 1 . The four supporting legs 13 are respectively located at four corners of the base 1 and can support the base 1 .

[0034] Example 2

[0035] like Figure 2 As shown, a short connecting plate 1101 is hinged on the side of the left conveying base plate 1001 close to the right conveying base plate 1002, and a long connecting plate 1102 is hinged on the side of the right conveying base plate 1002 close to the left conveying base plate 1001. The outer end of the short connecting plate 1101 is hinged at the middle of the long connecting plate 1102. Both the short connecting plate 1101 and the long connecting plate 1102 are close to the middle side of the workbench 1 and extend out of the workbench 1. A handle 12 is welded at the outer end of the long connecting plate 1102. Applying a pushing force to the handle 12 can realize the opposite movement of the two conveying base plates 10, thereby making the chamfering tables 2 approach each other.

[0036] The workpiece barrel joint is fixed on the spindle 2, and the claw 14 is further clamped, pushing the external handle 12 to reduce the angle at which the short connecting plate 1101 and the long connecting plate 1102 are hinged to each other, so that the bottom plate 10 corresponding to the short connecting plate 1101 and the long connecting plate 1102 are close to each other through the guide rail 9, and the chamfering tool 5 protruding inward can automatically find the hole center through the limiter 6 and correct the angle, so as to extend into the hole of the workpiece to chamfer it. The motor 4 on the outside of the chamfering table 2 provides power for the corresponding multi-axis device inside the chamfering table 2. After the chamfering process is completed, slowly release the handle 12 to make the bottom plate 10 gradually move away from the workpiece fixing seat 3 and return to the initial position. After the process is completed, the workpiece is removed.

[0037] The telescopic cylinder assembly 20 and the connecting plate 11 can be arranged on the same chamfering equipment. When the electric telescopic cylinder assembly 20 fails, the connecting plates 11 can be manually pushed closer to each other for chamfering. Or when a small batch of workpieces need to be chamfered, a manual method can be used to save resources and costs.

[0038] The two chamfering tables 2 are connected to a total of six chamfering tools 5. The six chamfering tools 5 start working at the same time, and can complete the chamfering process quickly at one time, effectively improving the chamfering work efficiency. At the same time, the chamfering of the workpiece is uniform without omissions. The use of this double-sided six-hole synchronous floating chamfering equipment can also ensure the safety of workers.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
