Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing equipment, and more specifically to a double wheel hub clamping device for industrial robots. Background Technology

[0002] After the existing car wheel hubs are machined, before each processing, the wheel hubs need to be transported from one side of the conveyor to the other side, or installed from one side of the conveyor to the corresponding processing station for processing. In both cases, industrial robots are required to continuously grab and place the wheel hubs.

[0003] Therefore, existing industrial robots all need to install a gripping mechanism at the end of the manipulator. The existing gripping mechanism is generally a single gripping device or a double gripping device. A single gripping device can only grip a single wheel hub, while a double gripping device can grip two wheel hubs.

[0004] In existing dual-clamping devices, the clamping force is generally driven by cylinders or hydraulic cylinders. However, in machining environments, after wheel hub machining, there will be a large amount of dust or debris on the surface. The debris will fall off directly when the clamping mechanism is in use, while the dust will fall and adhere to the clamping mechanism, especially on the surfaces of some guide rods or hydraulic cylinder push rods. Although the dust on the surface will be pushed out by the guide sleeve during the movement of the guide rod or the extension and retraction of the hydraulic cylinder push rod, it will still accumulate on the surface of the hydraulic cylinder and other parts over time. Once the sealing structure of the guide sleeve is damaged, this dust will enter, causing jamming, requiring maintenance, increasing maintenance costs, and requiring machine shutdown during maintenance, which will affect production. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dual-hub clamping device for industrial robots. This device can reduce the amount of dust entering the connecting cover during clamping, allowing internal components to be used normally for a long time, reducing the frequency of maintenance and downtime, and ensuring processing efficiency.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A dual-hub clamping device for an industrial robot includes a main connecting fixing plate. Connecting covers are fixed to the left and right sides of the bottom surface of the main connecting fixing plate. Each connecting cover has a fixing part for two clamping members installed in it, and the outer clamping parts of the two clamping members are located on the outside of the corresponding connecting cover.

[0008] The outer and inner ends of the opposite walls of the outer clamping parts of the two corresponding clamping parts are fixed with connecting blocks. The middle of the connecting blocks is movably connected to a vertical support rod through a bearing. A clamping wheel is fixed on the vertical support rod.

[0009] A blower fan is fixed in the middle of the bottom surface of the bottom plate of the connecting cover. The air outlet of the blower fan faces the through hole in the middle of the bottom plate of the connecting cover. A filter screen is fixed on the bottom surface of the blower fan, which covers the air inlet at the bottom of the blower fan.

[0010] The connecting cover includes front and rear side support parts fixed to the bottom surface of the main connecting fixing plate, and the bottom surfaces of the two side support parts are fixed to the same base plate.

[0011] Two clamping cylinders are fixed on the bottom surface of the main connecting plate between the two side support parts. The fixing parts of the two clamping parts are located between the corresponding two side support parts, and the ends of the push rods of the two clamping cylinders are in opposite directions.

[0012] The end of the push rod of the clamping cylinder is fixed on the inner side wall of the fixing part of the corresponding clamping member. Multiple outer guide rods are fixed on the outer side walls of the fixing parts of the two clamping members. The outer guide rods are inserted into the guide sleeves fixed in the guide through holes formed on the corresponding side support parts.

[0013] Both clamping parts have intermediate guide rods fixed at their respective wall surfaces. The intermediate guide rods are inserted into guide fixing sleeves fixed on the bottom surface of the main connecting fixing plate, and the outer side wall of the intermediate guide rod is in close contact with the inner side wall of the corresponding guide fixing sleeve.

[0014] The clamping member includes a fixing part extending to the left and right, the outer end of the fixing part extending out of the connecting cover and forming an outwardly extending outer clamping part.

[0020] For example, see below. Figures 1 to 3As shown, a dual-hub clamping device for an industrial robot includes a main connecting fixing plate 10. A connecting adapter 15 is fixed to the center of the top surface of the main connecting fixing plate 10. A flange connection part is formed at the top of the connecting adapter 15. During installation, it is fixedly connected to the end of the manipulator of the industrial robot through the flange connection part.

[0021] The bottom surface of the main connecting fixing plate 10 is fixed with connecting cover 20 on the left and right sides. Each connecting cover 20 is equipped with fixing parts of two clamping members 30, and the outer clamping parts 31 of the two clamping members 30 are located on the outside of the corresponding connecting cover 20.

[0022] The outer and inner ends of the opposite walls of the outer clamping parts 31 of the two corresponding clamping parts 30 are fixed with connecting blocks. The middle of the connecting blocks is movably connected to a vertical support rod 32 through a bearing. A clamping wheel 33 is fixed on the vertical support rod 32.

[0023] A blower fan 40 is fixed in the middle of the bottom surface of the bottom plate of the connecting cover 20. The air outlet of the blower fan 40 faces the through hole in the middle of the bottom plate of the connecting cover 20. A filter screen 41 is fixed on the bottom surface of the blower fan 40, which covers the air inlet at the bottom of the blower fan 40. In this embodiment, after a certain period of use, the filter screen 41 needs to be replaced to prevent the mesh of the filter screen 41 from being blocked by dust and reducing the exhaust volume of the blower fan 40.

[0024] Furthermore, the connecting cover 20 includes front and rear side support parts 21 fixed to the bottom surface of the main connecting fixing plate 10, and the bottom surfaces of the two side support parts 21 are fixed to the same base plate.

[0025] Two clamping cylinders 11 are fixed on the bottom surface of the main connecting fixing plate 10 between the two side support parts 21. The fixing parts of the two clamping parts 30 are located between the corresponding two side support parts 21, and the ends of the push rods of the two clamping cylinders 11 are in opposite directions.

[0026] The end of the push rod of the clamping cylinder 11 is fixed on the inner side wall of the fixing part of the corresponding clamping member 30. Multiple outer guide rods 34 are fixed on the outer side walls of the fixing parts of the two clamping members 30. The outer guide rods 34 are inserted into the guide sleeves fixed in the guide through holes formed on the corresponding side support part 21.

[0027] Furthermore, intermediate guide rods 35 are fixed at the opposite wall surfaces of the fixing parts of the two clamping members 30. The intermediate guide rods 35 are inserted into the guide fixing sleeves 12 fixed on the bottom surface of the main connecting fixing plate 10, and the outer side wall of the intermediate guide rods 35 is in close contact with the inner side wall of the corresponding guide fixing sleeves 12.

[0028] Furthermore, the clamping member 30 includes a fixing part extending to the left and right, the outer end of the fixing part extending out of the connecting cover 20 and forming an outwardly extending outer clamping part 31.

[0029] The top and bottom of the vertical support rod 32 extend out of the top and bottom surfaces of the connecting block and are fixed with clamping wheels 33.

[0030] The clamping member 30 has a fixed part with a proximity switch 1 on one side wall of the corresponding side support part 11, and the sensing end of the proximity switch 1 faces the side wall of the corresponding side support part 11.

[0031] An elastic anti-slip rubber sleeve 331 is fitted on the outer wall of the clamping wheel 33. This structure reduces friction on the wheel hub surface when clamping the wheel hub, thus ensuring the surface quality of the wheel hub.

[0032] In this embodiment, the clamping cylinder 11 is connected to the corresponding control valve of the hydraulic system through a connecting pipe. When the hydraulic system is running, the control valve is activated, thereby extending and retracting the push rod of the clamping cylinder 11. The electrical components of the hydraulic system, the blower fan 40, and the proximity switch 1 are electrically connected to the control host through electrical connection lines. The operation is controlled by the control host. This is a conventional structure and will not be described in detail here.

[0033] In this embodiment, the blower fan 40 is always running, blowing air into the connecting cover 20 to prevent external dust from easily entering the connecting cover 20 and to prevent dust from adhering to its internal components. During use, the wheel hub is clamped between the elastic anti-slip rubber sleeves 331 of the eight clamping wheels 33 by the retraction of the push rods of the corresponding two clamping cylinders 11. When placing, the two clamping parts 30 are pushed away by the push rods of the corresponding two clamping cylinders 11, so that the two clamping parts 30 are moved away, and the wheel hub is released. When the two clamping parts 30 are moved away and returned to their original positions, the sensing end of the proximity switch 1 will approach the side wall of the corresponding side support 11 until it is pushed into place. The sensing end of the proximity switch 1 senses the corresponding side support 11, indicating that it is in the open state.

[0034] This embodiment can grasp two wheel hubs for movement and transportation, with good handling effect. Through the grasping and placement of the industrial robot, two wheel hubs can be accurately placed in the required position, resulting in good performance.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
