Description

Technical Field

[0001] This utility model relates to the field of wheel hub clamping technology, specifically to a dual-station wheel hub handling clamp. Background Technology

[0002] In wheel manufacturing, the clamping and handling of components is a crucial step in ensuring machining accuracy and efficiency. From casting blanks to finished product assembly and painting, different processes require specialized fixtures. Modern fixtures generally employ modular designs, adapting to different wheel specifications by changing the grippers. Some high-end production lines are equipped with six-axis robots paired with force-controlled fixtures, enabling real-time adjustment of clamping force to prevent deformation of aluminum alloy wheels. The introduction of vision positioning systems allows fixtures to automatically compensate for dimensional deviations in wheel blanks. Fixtures can also be integrated into MES systems, allowing for the tracking of data such as pressure and position during each clamping operation, which is essential for analyzing machining defects. With the increasing demand for lightweighting, carbon fiber wheel fixtures have also incorporated anti-static and surface protection features.

[0003] Application announcement number CN119329975A discloses an automatic feeding and painting conveyor line for automobile wheel hubs and its usage method. According to its instruction manual and drawings, the electric push rod pushes the lifting ring to move upward. When the lifting ring moves, it pushes the through-hole pressure plate to move upward through the connecting plate. When the through-hole pressure plate moves, it squeezes the extrusion rod and pushes the slide rod to slide on the inner wall of the round hole rod through the through-hole pressure plate. When the slide rod slides, it pushes the rubber pad to clamp and fix the automobile wheel hub through the connection between the arc plate and the rubber pad.

[0004] However, the solution has certain limitations: 1. The clamping structure for the wheel hub is relatively complex. While achieving the function of clamping the wheel hub at multiple stations, this design increases the overall manufacturing cost of the fixture; 2. After the four arc plates clamp the wheel hub, the contact area between the four arc plates and the side wall of the wheel hub is large, which further increases the risk of scratching the side wall of the wheel hub. Summary of the Invention

[0005] This utility model mainly addresses the problems existing in the production and use of multi-station wheel hub clamps. It has invented a dual-station wheel hub handling clamp. The two stations at the bottom of the connecting seat use piston rods to pull the cylinder body to slide on the surface of the guide rod, so that the clamping component at the bottom of the clamp beam automatically completes the clamping of the wheel hub, which can realize the function of multi-station wheel hub clamping.

[0006] The purpose of this invention is achieved through the following technical solution: a dual-station wheel hub handling fixture, including a detachable connecting seat installed at the end of an industrial robot, clamping support members disposed at both ends of the connecting seat, each clamping support member having a plurality of slidable clamping beams at its bottom and a driving assembly for driving the clamping beams to slide, and each clamping beam having a clamping assembly for clamping a wheel hub at its end.

[0007] Preferably, the bottom of the connecting seat is provided with a support wall plate in the middle, and both ends of the connecting seat are provided with driving components. One side of each driving component is connected to the support wall plate, and each driving component can clamp the wheel hub when it drives the clamping component to slide towards the support wall plate.

[0008] Preferably, the drive assembly includes a guide rod, a piston rod, and a cylinder. Each clamping beam is disposed at the bottom of the cylinder. Several guide rods are provided between the end of each support wall plate and the connecting seat. The cylinder is slidably connected to the surface of the guide rods. One end of the piston rod is connected to the inside of the cylinder, and the other end of the piston rod is connected to the support wall plate. The sliding between the piston rod and the cylinder is achieved by pneumatic means.

[0009] Preferably, the bottom of the cylinder is provided with several locking through holes, and each clamping beam can be detachably installed in the locking through holes. This setting can change the distance between the clamping beams in the initial state and the final state, so that the subsequent clamping assembly can clamp wheel hubs of different diameters.

[0010] Preferably, the clamping assembly includes a clamping support seat, a clamping wheel shaft, and a supporting clamping wheel. Each clamping beam has a clamping support seat detachably mounted on both sides. Each clamping support seat has a clamping wheel shaft inside, and each clamping wheel shaft has a supporting clamping wheel at its end.

[0011] Preferably, each of the supporting clamping wheels has a groove on its surface, and a polyurethane ring is provided inside each groove. A reinforcing plate that can enhance the support is also provided between adjacent clamping wheel shafts. The setting of the reinforcing plate ensures that the polyurethane ring of the supporting clamping wheel is subjected to more stable force when clamping the wheel hub.

[0012] Preferably, the bottom of the reinforcing plate is provided with a photoelectric support base and a photoelectric sensor installed inside the photoelectric support base. The bottom of the support clamping wheel is also provided with a proximity switch. The photoelectric sensor is mainly used to determine whether there is material placed between adjacent support clamping wheels. The contacts of the proximity switch close under the pressure of the wheel hub, thereby transmitting a signal that the clamping is in place.

[0013] Preferably, the surface of the connecting seat is also provided with several protective covers, and each of the protective covers is provided with a solenoid valve for controlling the intake and exhaust of air inside the cylinder. This arrangement is to realize the control of the movement between the piston rod and the cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this solution, the piston rod pulls the cylinder to slide on the surface of the guide rod, so that the clamping component at the bottom of the fixture beam automatically completes the clamping of the wheel hub. The whole solution reduces the production cost of the entire fixture while realizing the function of clamping wheel hubs in multiple positions.

[0016] 2. During clamping, the force is mainly borne between the polyurethane ring and the side wall of the wheel hub. The self-adaptive deformation of the polyurethane ring maintains the stability of the clamping force and reduces scratches on the side wall of the wheel hub. Therefore, the detachable design between the polyurethane ring and the slot makes it easier to replace the polyurethane ring later, which can extend the service life of the entire clamp.

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0023] like Figure 1 , Figure 2 and Figure 4As shown, a dual-station wheel hub handling fixture includes a detachable connecting seat 1 mounted on the end of an industrial robot, and clamping support members 2 disposed at both ends of the connecting seat 1. The clamping support members 2 are plate-shaped. The surface of the connecting seat 1 is also provided with several protective covers 12, and each of the protective covers 12 is provided with a solenoid valve 13 for controlling the air intake and exhaust of the cylinder 43.

[0024] In this embodiment, each clamping support 2 has several sliding clamping beams 3 and a driving assembly 4 for driving the clamping beams 3 to slide at its bottom. The bottom of the connecting seat 1 has a supporting wall plate 11 in the middle, and both ends of the connecting seat 1 are provided with driving assemblies 4, with one side of each driving assembly 4 connected to the supporting wall plate 11.

[0025] The drive assembly 4 includes guide rods 41, piston rods 42, and cylinders 43. Each clamping beam 3 is located at the bottom of the cylinder 43. Several guide rods 41 are provided between the end of each support wall plate 11 and the end of the connecting seat 1. The cylinder 43 is slidably connected to the surface of the guide rods 41. One end of the piston rod 42 is connected to the inside of the cylinder 43, and the other end of the piston rod 42 is connected to the support wall plate 11. The sliding between the piston rod 42 and the cylinder 43 is achieved pneumatically.

[0026] When the cylinder 43 is in intake or exhaust mode, since one end of the piston rod 42 is fixed to the side wall of the support wall plate 11, the piston rod 42 can pull the cylinder 43 to slide on the surface of the guide rod 41. The change in position of the opposing cylinder 43 can cause the position of the clamping beam 3 mounted at the bottom of the cylinder 43 to change.

[0027] The bottom of the cylinder body 43 is provided with several locking through holes 431, and each clamping beam 3 is detachably installed in a locking through hole 431. The locking through holes 431 are distributed on both sides of the bottom of the cylinder body 43, therefore the distance between adjacent clamping beams 3 is different when they are installed inside the locking through holes 431 on the left and when they are installed inside the locking through holes 431 on the right. This allows the distance between the clamping beams 3 to be changed in the initial and final states, so that the subsequent clamping assembly 5 can clamp hubs of different diameters.

[0028] Please refer to point 3. In this embodiment, each clamping beam 3 has a clamping assembly 5 at its end capable of clamping the wheel hub. When each driving assembly 4 drives the clamping assembly 5 to slide towards the support wall plate 11, it can clamp the wheel hub.

[0029] The clamping assembly 5 includes a clamping support base 51, a clamping wheel shaft 52, and a supporting clamping wheel 53. Each clamping beam 3 has a clamping support base 51 detachably mounted on both sides. Each clamping support base 51 has a clamping wheel shaft 52 inside, and each clamping wheel shaft 52 has a supporting clamping wheel 53 at its end. Each supporting clamping wheel 53 has a groove 531 on its surface, and a polyurethane ring 54 is provided inside each groove 531. A reinforcing plate 55 is also provided between adjacent clamping wheel shafts 52 to enhance support.

[0030] When the position of the clamp beam 3 changes, it simultaneously drives the clamping support seats 51 installed on both sides to change position. The clamping support seats 51, in turn, drive the clamping wheel shaft 52 and the support clamping wheel 53 at the end of the clamping wheel shaft 52 to change position. Gradually, the opposing polyurethane rings 54 are brought into contact with the side wall of the wheel hub until the wheel hub is completely clamped.

[0031] Since the force is mainly borne between the polyurethane ring 54 and the side wall of the hub during each clamping operation, the adaptive deformation of the polyurethane ring 54 can still maintain the stability of the clamping force. Therefore, the polyurethane ring 54 is a consumable part. The detachable design between the polyurethane ring 54 and the slot 531 makes it easier to replace the polyurethane ring 54 in the future, which can extend the service life of the entire fixture.

[0032] In this embodiment, the bottom of the reinforcing plate 55 is provided with a photoelectric support base 56 and a photoelectric sensor 57 installed inside the photoelectric support base 56. The bottom of the support clamping wheel 53 is also provided with a proximity switch 58. During the entire clamping process, the photoelectric sensor 57 is mainly used to determine whether there is material placed between adjacent support clamping wheels 53. When the polyurethane ring 54 deforms against the side wall of the wheel hub, the contact of the proximity switch 58 closes under the pressure of the wheel hub, thereby transmitting a signal that the clamping is in place.

[0033] Working principle and usage of this utility model:

[0034] When the cylinder 43 is in the exhaust phase, since one end of the piston rod 42 is fixed to the side wall of the support wall plate 11, the piston rod 42 can pull the cylinder 43 to slide on the surface of the guide rod 41. The change in position of the opposing cylinder 43 can cause the position of the clamping beam 3 installed at the bottom of the cylinder 43 to change. When the position of the clamping beam 3 changes, it can simultaneously drive the clamping support seats 51 installed on both sides to change position, and the clamping support seats 51 can simultaneously drive the clamping wheel shaft 52 and the support clamping wheel 53 at the end of the clamping wheel shaft 52 to change position. Gradually, the opposing polyurethane ring 54 is brought into contact with the side wall of the wheel hub until the wheel hub is completely clamped.

[0035] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
