[0029] Reference Figures 1 to 5 The utility model discloses a vehicle pedal arm floating sleeve device, including a support 1 arranged on a machine platform, a turntable 2 is also provided on the machine platform of the present application, and a plurality of annularly evenly distributed clamps 3 are provided on the turntable 2, and the turntable 2 is provided with a driving system, which can transmit the rubber seat and the cantilever rod 4 to the corresponding workstation for assembly by rotation. Of course, the clamp 3, the turntable 2 and the driving system are prior arts and are not the application points of the present application, so the specific structure is not described in detail, the clamp 3 clamps the rubber seat, and one end of the cantilever rod 4 is suspended in the air, and the support 1 is located next to the turntable 2, and a driving unit 5 and a push plate 6 driven by the driving unit 5 are provided on the support 1, and the driving unit 5 is a cylinder, and the push plate 6 is fixed to the piston rod of the cylinder, and a sleeve seat 7 is provided on the push plate 6, and a pipe seat hole 8 is provided in the sleeve seat 7, and a floating sleeve assembly 9 is provided in the pipe seat hole 8, and the floating sleeve assembly There is a certain floating gap between the component 9 and the inner wall of the tube seat hole 8, and a limiting structure 1 is provided between the floating sleeve component 9 and the tube seat hole 8 to limit the floating sleeve component 9 from escaping from the tube seat hole 8. Through the above structure, it can be ensured that the floating sleeve component 9 has a certain adjustment space in the tube seat hole 8, a core hole 11 is provided in the floating sleeve component 9, a core rod 12 is provided in the core hole 11, an elastic component 13 for squeezing the core rod 12 is provided between the core rod 12 and the floating sleeve component 9, and a limiting structure 2 is provided between the floating sleeve component 9 and the core rod 12 to limit the core rod 12 from escaping from the core hole 11. Through the above structure, the core rod 12 can be abutted against the end of the cantilever rod 4, and the other end of the core rod 12 can be abutted against the bottom surface of the core hole 11 to limit the position. At this time, the floating sleeve component 9 can no longer descend, thereby avoiding the position deviation of the hose 100 from exceeding the preset value.

[0030] As shown in the figure, a centering extrusion surface 15 capable of extruding the rubber hose 100 is provided at the orifice of the core hole 11. Because the cantilever rod 4 of the present application is a relatively thick metal rod and is an irregular shape formed after multiple bendings, the relative position accuracy between the cantilever rod 4 and the rubber seat is not high, including the dimensional accuracy of the cantilever rod 4 itself. Therefore, it is difficult for the hole wall end face of the core hole 11 to be directly extruded with the rubber hose 100, because the end of the cantilever rod 4 needs to be exposed, so in the final extrusion process, the end of the cantilever rod 4 needs to be inserted into the core hole 11, so we need to use the hole wall end face of the core hole 11 to extrude the tube end face of the rubber hose 100. Because the cantilever rod 4 has low accuracy, it is difficult to directly align the core hole 11 with the rubber hose 100 coaxially. We A centering extrusion surface 15 is designed to achieve error compensation. The centering extrusion surface 15 is an annular inclined surface, so that a tapered hole with a wide lower opening and a narrow upper opening is formed at the end of the core hole 11. In this way, the end face of the hose 100 is easily aligned with the lower opening of the tapered hole, so that the hose 100 can be punched until the end of the cantilever rod 4 exposes the hose 100. At this time, the end of the cantilever rod 4 will also contact the centering extrusion surface 15 and be guided to be inserted into the core hole 11. Of course, the thicker the wall of the tapered hole, the more it can compensate for larger errors. If the core hole 11 is not coaxial with the cantilever rod 4, and the floating sleeve assembly 9 is fixed, the cantilever rod 4 and the core hole 11 will be stuck. Therefore, the floating sleeve assembly 9 can keep coaxial with the cantilever rod 4 by fine-tuning its own position through the floating gap, and no jamming will occur.

[0031] In the above, of course, the diameter of the inner hole of the pressing tube must be larger than the rod diameter of the cantilever rod 4, and the diameter of the inner hole of the pressing tube must be smaller than the tube diameter of the hose 100, so as to ensure that the hose 100 can be squeezed and the hose 100 passing through the end of the cantilever rod 4 will not conflict with the pressing tube.

[0032] As shown in the figure, the support 1 is provided with an upper support plate and a lower support plate, and the driving unit 5 is fixed on the upper support plate. The upper support plate and the lower support plate are both provided with sliding holes, and a matching sliding shaft 16 is provided in the sliding hole. The end of the sliding shaft 16 is fixed to the push plate 6. The push plate 6 is guided by the sliding shaft 16, and the lifting and lowering of the push plate 6 is more stable.

[0033] As shown in the figure, the sleeve seat 7 includes a base 17 and a sleeve 18. The base 17 is fixed to the push plate 6. The base 17 has a seat tube. The sleeve 18 is sleeved on the seat tube and fixed by a top screw. The pipe seat hole 8 passes through the base 17 and the sleeve 18. The limiting structure 1 is a step surface 10 set in the sleeve 18 and an annular boss 14 set on the floating sleeve assembly 9. The annular boss 14 can be against the step surface 10. The annular boss 14 is set on the outer wall of the connecting pipe. Through the above structure, we only need to disassemble the sleeve 18 to remove the floating sleeve assembly 9 from the sleeve seat 7, which is convenient for subsequent maintenance.

[0034] As shown in the figure, the floating casing assembly 9 also includes a pressing tube 19, a connecting tube 20 and an end block 21. The pressing tube 19, the connecting tube 20, the end block 21, the core rod 12 and the elastic member 13 form a whole. One end of the pressing tube 19 is inserted into the connecting tube 20 and is threadedly connected to the connecting tube 20. The end block 21 is threadedly connected to the other end of the connecting tube 20. The core hole 11 is composed of the inner holes of the end block 21, the pressing tube 19 and the connecting tube 20. The surface of the end block 21 constitutes the bottom of the core hole 11. The above structure is not only convenient for production and assembly, but also convenient for maintenance and cleaning. Because when stamping the rubber hose 100, the place in contact with the rubber hose 100 will inevitably be glued, so it often needs to be removed for cleaning. Therefore, in the above structure, we can remove the pressing tube 19 separately for replacement, and if the pressing tube 19 is damaged, the replacement cost is also low.

[0035] As shown in the figure, the second limiting structure is a step surface 22 arranged in the connecting tube 20 and an annular boss 23 arranged on the core rod 12. The annular boss 23 can be abutted against the step surface 22. The elastic member 13 is a spring. The spring sleeve is placed on the core rod 12. One end of the spring abuts against the end block 21 and the other end of the spring abuts against the annular boss 23. In this way, even if the spring squeezes the core rod 12, the core rod 12 will not fall out of the core hole 11.

[0036] As shown in the figure, it also includes a clamping structure, which includes a clamping seat 27 and a clamping claw cylinder 28 arranged on the clamping seat 27. A clamping plate 29 is provided on the clamping claw of the clamping claw cylinder 28. A clamping groove is provided on the edge of the clamping plate 29. Because the clamping groove should avoid the rubber hose 100, the contact area with the cantilever rod 4 is small, so an auxiliary roller is relatively set for clamping. The auxiliary roller can roll, so it does not affect the insertion of the rubber hose. The cantilever rod 4 needs to be moved to the next process, so the clamping claw cylinder 28 is connected to the pushing cylinder 31 through a connecting plate. When the rubber sleeve needs to be clamped, it is pushed to a predetermined position by the pushing cylinder 31 for clamping, and returns to its original position after the clamping is completed.

[0037] As shown in the figure, it also includes a support positioning structure, which includes a support positioning seat 24 located on the machine platform, a support positioning cylinder 25 and a support positioning block 26 connected to the support positioning cylinder 25 are provided on the support positioning seat 24, and a support positioning groove 30 for supporting and positioning the cantilever rod is provided on the support positioning block 26. After all, the hose 100 has to withstand the impact of stamping, and the cantilever rod 4 is suspended, so it is necessary to set a support positioning groove 30 for supporting the cantilever rod 4 under the cantilever rod 4. The cantilever rod 4 is supported when needed by the support positioning cylinder 25. When subjected to impact, the cantilever rod 4 will not deviate or sink. After the casing is completed, it is driven back by the support positioning cylinder 25.

[0038] The principle of this structure is as follows: first, the rubber hose 100 is manually sleeved on the end of the cantilever rod 4, and then the glue gun 200 applies glue to the rubber hose 100, and the driving unit 5 starts to work to drive the push plate 6 to press down, and the push plate 6 pushes the end block 21 to descend, thereby driving the entire floating sleeve assembly 9 to descend. During the descent, the end of the core rod 12 will be inserted into the rubber hose 100, and the end surface of the tube wall of the pressing tube 19 will contact the end surface of the tube wall of the rubber hose 100 to punch the rubber hose 100 until the rubber hose 100 is completely sleeved on the predetermined position on the cantilever rod 4, and then the driving unit 5 drives the push plate 6 and the floating sleeve assembly 9 to reset, and the core rod 12 is reset by the spring at the same time, waiting for the next work.
