Description

Technical Field

[0001] This utility model relates to the technical field of motorcycle wheel hub production equipment, and in particular to a clamping device for grinding motorcycle wheel hubs. Background Technology

[0002] A motorcycle wheel rim is a cylindrical metal component that supports the tire and is centrally mounted on an axle. It is also called a wheel rim, steel rim, wheel hub, or rim wheel. During the manufacturing process, motorcycle wheel rims are typically polished using a wheel rim polishing device to remove burrs, uneven areas, and improve surface finish.

[0003] Before grinding the end face of a motorcycle wheel hub, a clamping device is first used to hold and fix the wheel hub. Then, a grinding device is used to grind the end face of the wheel hub. Currently, when the existing clamping device holds the motorcycle wheel hub, part of the clamping device is clamped on the end face. This means that the part of the motorcycle wheel hub covered by the clamping device cannot be ground during the grinding process, and workers need to manually perform secondary grinding, resulting in low grinding efficiency of motorcycle wheel hubs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a clamping device for grinding motorcycle wheel hubs, which solves the problem that existing wheel hub grinding clamping devices cover part of the end face of the wheel hub when clamping the wheel hub.

[0005] According to an embodiment of the present invention, a clamping device for grinding motorcycle wheel hubs includes: a base plate, a support base, and sliding rods. A bracket is provided at the bottom of the base plate, and the support base is provided at the top of the base plate. An arc-shaped support groove is provided at the top of the support base. There are two sliding rods, both of which pass vertically through the base plate. Two sliding grooves are symmetrically provided at the top of the base plate for the two sliding rods to slide in the horizontal direction. The two sliding rods are distributed on both sides of the support base. Clamping components are provided on the opposite sides of the two sliding rods. A driving component for driving the two sliding rods to move closer or further apart is provided on the bracket.

[0006] Compared with the prior art, the present invention has the following advantages: by setting a support base on the top of the base plate, and setting an arc-shaped support groove on the top of the support base, the support groove is used to support the motorcycle wheel hub. The two sliding rods are driven by the drive assembly to move closer to each other, so that the two clamping assemblies on opposite sides of the two sliding rods clamp the wheel hub from both sides. The wheel hub is fixed in the above way without covering the end face of the wheel hub, which facilitates the grinding and processing of the end face of the wheel hub. Compared with the existing wheel hub clamping device, it can improve the efficiency of grinding and processing the end face of the wheel hub.

[0007] Furthermore, each of the clamping components includes: a mounting base, a clamping base, and a locking mechanism. The clamping base is arc-shaped and is detachably fixed to the side wall of the mounting base by the locking mechanism. The mounting base is fixed to the side wall of the sliding rod.

[0008] Furthermore, each of the aforementioned locking mechanisms includes: a fixed seat, a connecting rod, and an insert rod. There are two fixed seats, which are detachably fixed to the two side walls of the mounting base by locking screws. The side walls of the two fixed seats are provided with connecting rods extending toward the clamping seat. The side walls of the two connecting rods near the clamping seat are provided with insert rods. The two side walls of the clamping seat are provided with slots for inserting the two insert rods respectively.

[0009] Furthermore, clamping pads are provided on opposite sides of both clamping seats.

[0010] Furthermore, a hydraulic cylinder is provided between the bottom of the support base and the top of the base plate, and the hydraulic cylinder is used to drive the support base to move in the vertical direction.

[0011] Furthermore, the drive assembly includes a lead screw and a motor. The lead screw is horizontally and rotatably mounted on the bracket, and the motor is fixed to the side wall of the bracket by a fixing block. The output end of the motor is fixedly connected to one end of the lead screw, and the lead screw passes horizontally through the two sliding rods. The lead screw and the two sliding rods are both threadedly connected.

[0012] Furthermore, a support pad is provided on the top of the support groove. Attached Figure Description

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1As shown in the figure, this utility model embodiment proposes a clamping device for grinding motorcycle wheel hubs, including: a base plate 1, a support seat 4, and sliding rods 3. A bracket 2 is provided at the bottom of the base plate 1, and the support seat 4 is provided at the top of the base plate 1. An arc-shaped support groove is provided at the top of the support seat 4. There are two sliding rods 3, both of which pass vertically through the base plate 1. Two sliding grooves are symmetrically provided at the top of the base plate 1 for the two sliding rods 3 to slide in the horizontal direction, and the two sliding rods 3 are distributed on both sides of the support seat 4. Clamping components are provided on the opposite sides of the two sliding rods 3. A driving component is provided on the bracket 2 for driving the two sliding rods 3 to move closer or further apart.

[0018] By setting a support base 4 on the top of the base plate 1, and setting an arc-shaped support groove on the top of the support base 4, the support groove is used to support the motorcycle wheel hub 5. The two sliding rods 3 are driven by the drive assembly to move closer to each other, so that the two clamping assemblies on opposite sides of the two sliding rods 3 clamp the wheel hub 5 from both sides. The wheel hub 5 is fixed in the above way without covering the end face of the wheel hub 5, which facilitates the grinding of the end face of the wheel hub 5. Compared with the existing wheel hub clamping device, it can improve the efficiency of grinding the end face of the wheel hub 5.

[0019] like Figure 2 As shown, each clamping assembly includes: a mounting base 6, a clamping base 7, and a locking mechanism. The clamping base 7 is arc-shaped and is detachably fixed to the side wall of the mounting base 6 by the locking mechanism. The mounting base 6 is fixed to the side wall of the sliding rod 3. Each locking mechanism includes: a fixing base 8, a connecting rod 12, and an insert rod 10. There are two fixing bases 8, which are detachably fixed to the two side walls of the mounting base 6 by locking screws 9. The side walls of the two fixing bases 8 are provided with connecting rods 12 extending toward the clamping base 7. The two connecting rods 12 are provided with insert rods 10 near the side wall of the clamping base 7. The two side walls of the clamping base 7 are provided with slots for inserting the two insert rods 10.

[0020] Specifically, clamping pads 11 can be provided on opposite sides of the two clamping seats 7, and a support pad 17 can be provided on the top of the support groove. Both the support pad 17 and the clamping pad 11 are made of rubber material to prevent the outer surface of the wheel hub 5 from being crushed during the clamping process. A hydraulic cylinder 13 is provided between the bottom of the support seat 4 and the top of the base plate 1 to adjust the height of the support seat 4 so that the support groove and the two clamping seats 7 can be on the same ring, which is convenient for clamping the wheel hub 5. It is also convenient for clamping and fixing wheel hubs 5 of different diameters.

[0021] like Figure 1As shown, the drive assembly includes a lead screw 14 and a motor 16. The lead screw 14 is horizontally and rotatably mounted on the bracket 2. The motor 16 is fixed to the side wall of the bracket 2 by a fixing block 15. The output end of the motor 16 is fixedly connected to one end of the lead screw 14, and the lead screw 14 passes horizontally through the two sliding rods 3. The lead screw 14 and the two sliding rods 3 are threadedly connected.

[0022] The working principle of this clamping device is as follows: First, the hub 5 is supported on the top of the support groove. Then, the hydraulic cylinder 13 pushes the support seat 4 to move vertically, so that the axis of the hub 5 coincides with the center of the arc where the two clamping seats 7 are located. Then, the motor 16 drives the lead screw 14 to rotate, and the lead screw 14 drives the two sliding rods 3 to move closer to each other, so that the two clamping seats 7 clamp the hub 5 from both sides. When it is necessary to release the hub 5, the motor 16 is controlled to drive the lead screw 14 to reverse.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
