DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1As shown in FIG. 3 , an embodiment of the utility model proposes a clamp for processing a motorcycle fuel tank, comprising a base plate 1, a screw rod 5 and a clamping assembly, a concave frame 2 is fixedly provided on the top of the base plate 1, a rotating shaft is rotatably provided at the opening of the concave frame 2, an L-shaped abutment plate 3 is fixedly provided on the rotating shaft, a first wedge block 4 is slidably provided at one end of the top of the base plate 1 away from the abutment plate 3; the concave frame 2 comprises an intermediate plate 201 and two wing plates 202, the two wing plates 202 are arranged at both ends of the intermediate plate 201 and are perpendicular to the intermediate plate 201, the screw rod 5 horizontally passes through the side wall of the intermediate plate 201 and is rotatably connected to the side wall of the first wedge block 4, and the screw rod 5 is threadedly connected to the intermediate plate 201; the clamping assembly is arranged on the top of the base plate 1, and the clamping assembly is used to clamp the motorcycle fuel tank placed on the base plate 1. In this embodiment, a recessed groove is provided at the top of one end of the bottom plate 1 close to the abutment plate 3, and the recessed groove is used to accommodate the horizontal portion of the L-shaped abutment plate 3. When the horizontal portion of the abutment plate 3 is accommodated in the recessed groove, the highest point of the horizontal portion of the abutment plate 3 is flush with the top of the bottom plate 1. When processing the motorcycle fuel tank, one end of the motorcycle fuel tank is abutted against the L-shaped abutment plate 3, so that the bottom edge of the motorcycle fuel tank is stuck at the corner of the L-shaped abutment plate 3, and then the entire motorcycle fuel tank is placed on the bottom plate 1, and then the screw rod 5 is rotated. In this embodiment, a cross handle is provided at one end of the screw rod 5 located outside the concave frame 2 for facilitating the turning of the screw rod 5. By rotating the screw rod 5, the screw rod 5 is screwed into the concave frame 2, thereby pushing the first wedge block 4 to abut against the motorcycle fuel tank. On the side wall of the motorcycle, the inclined surface of the first wedge block 4 faces the motorcycle fuel tank, so that the first wedge block 4 pushes one end of the motorcycle fuel tank to lift, and finally makes the inclined arc surface of the motorcycle fuel tank horizontal. At this time, the abutment block will rotate at a certain angle to adapt to the rotation of the motorcycle fuel tank. Finally, the two sides of the motorcycle fuel tank are clamped by the clamping assembly, which is convenient for workers to process the motorcycle fuel tank, such as processing the oil nozzle set on the inclined surface. When performing batch processing later, it is only necessary to loosen the clamping assembly, abut one end of the motorcycle fuel tank to be processed on the abutment plate 3 and the other end on the inclined surface of the first wedge block 4, and then clamp the two sides of the motorcycle fuel tank through the clamping assembly, thereby facilitating workers to process the inclined surface of the motorcycle fuel tank.

[0021] like Figure 1 and 3 As shown, further, the clamping assembly includes: a clamping plate 6, the clamping plates 6 are two pieces, the two clamping plates 6 are both located on the inner side of the two wing plates 202 of the concave frame 2, the two clamping plates 6 are both slidably connected with the bottom plate 1, and the bottom plate 1 is provided with a driving assembly for driving the two clamping plates 6 to move toward or away from each other. Specifically, after the first wedge block 4 and the abutting plate 3 cooperate to abut the inclined surface of the motorcycle fuel tank to be horizontal, the driving assembly is started, and the driving assembly pushes the two clamping plates 6 to clamp the motorcycle fuel tank. Since the driving assembly drives the two clamping plates 6 to move at the same time, the motorcycle fuel tank will be "centered", which can facilitate subsequent batch processing.

[0022] like Figure 1 and 3 As shown, further, the driving assembly includes: a bidirectional screw rod 7, a mounting groove is provided on the top of the base plate 1, the bidirectional screw rod 7 is horizontally and rotatably arranged in the mounting groove, the two ends of the bidirectional screw rod 7 are respectively threadedly connected to the two clamping plates 6, one end of the bidirectional screw rod 7 is connected to the first motor 8 after passing through the mounting groove, and the first motor 8 is fixedly connected to the side wall of the base plate 1. In this embodiment, the two clamping plates 6 are slidably arranged on the mounting groove through a connecting block, and the two ends of the bidirectional screw rod 7 are respectively threadedly connected to the two clamping plates 6. When clamping the motorcycle fuel tank, the first motor 8 is started, and the first motor 8 rotates to drive the bidirectional screw rod 7 to rotate. The clamping plates 6 at both ends of the bidirectional screw rod 7 move simultaneously along the length direction of the mounting groove under the push of the bidirectional screw rod 7, thereby achieving the purpose of clamping the motorcycle fuel tank.

[0023] like Figure 1 As shown, further, the inner walls of the two wing plates 202 of the concave frame 2 are provided with receiving grooves 9, and each receiving groove 9 is for receiving the corresponding clamping plate 6. In order to allow the device to clamp a wider motorcycle fuel tank, when necessary, the two clamping plates 6 can be received in the corresponding receiving grooves 9 to avoid the clamping plates 6 arranged on the inner sides of the two wing plates 202 blocking the motorcycle fuel tank from being placed in, so that the maximum width of the top of the bottom plate 1 for the motorcycle fuel tank to be placed in is increased.

[0024] like Figure 1 and 3 As shown, further, each side wall of the clamping plate 6 is provided with a rubber pad 10. Specifically, a plurality of protruding rubber particles are provided on the side wall of the rubber pad 10. When the rubber pad 10 of the side wall of the clamping plate 6 is pressed against the side wall of the motorcycle fuel tank, the rubber pad 10 is elastic and compressible, and is squeezed and deformed when clamped on the side wall of the motorcycle fuel tank, thereby generating greater lateral friction and pressure, thereby improving the stability of the clamping plate 6 when clamping the motorcycle fuel tank.

[0025] like Figure 2 —4, further, it also includes springs 11, both ends of the abutment plate 3 are arranged on the springs 11, and one end of each spring 11 away from the abutment plate 3 is fixedly connected to the end of the wing plate 202 of the concave frame 2. The spring 11 pulls the end of the L-shaped abutment plate 3 away from the bottom plate 1 to rotate toward the side wall of the concave frame 2, so that the abutment plate 3 always abuts against the side wall of the motorcycle fuel tank, which plays a positioning role.

[0026] like Figure 4As shown, further, it also includes a base 12, the top of the base 12 is recessed to form an installation cavity, a second motor 13 is fixedly arranged in the installation cavity, a rotating disk 14 is fixedly arranged vertically upward at the output end of the second motor 13, and the top of the rotating disk 14 is fixedly connected to the bottom of the bottom plate 1. In order to facilitate the processing of various positions of the motorcycle fuel tank, when necessary, the second motor 13 is started, the second motor 13 drives the rotating disk 14 to rotate, and the rotating disk 14 drives the bottom plate 1 to rotate, so that the worker does not need to move, and can turn the side of the motorcycle fuel tank away from himself to the side facing him, so as to facilitate the processing of this side of the motorcycle fuel tank.

[0027] like Figure 1 —4, further, it also includes a second wedge block 15, which is detachably arranged on the inclined surface of the first wedge block 4. Specifically, the inclined surface of the second wedge block 15 is arranged opposite to the inclined surface of the first wedge block 4, and is detachably connected by bolts or clamping. When it is not necessary to process the inclined surface of the motorcycle oil tank, the second wedge block 15 is arranged on the inclined surface of the first wedge block 4, and the side of the second wedge block 15 facing the abutment plate 3 is a straight surface. The second wedge block 15 cooperates with the abutment plate 3 to clamp and fix the motorcycle oil tank, which is convenient for workers to process the surface of the motorcycle oil tank.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
