Description

Technical Field

[0001] The present application relates to the technical field of hydraulic pumps, and in particular to a clamping tool for processing a pump casing. Background Art

[0002] A hydraulic pump is a device used to convert mechanical energy into hydraulic energy. It drives the rotational motion of mechanical energy to pump liquid (usually oil) from a low-pressure area to a high-pressure area to generate a high-pressure liquid flow, which is used to drive hydraulic cylinders, hydraulic motors or actuators in the hydraulic system, thereby realizing the operation and movement of construction machinery, industrial machinery and other equipment.

[0003] At present, in the process of processing the pump casing of the hydraulic pump, the pump casing needs to be stably clamped first, but the clamping steps of the existing clamping mechanism are relatively complicated, and most of them can only stably clamp the pump casing of the hydraulic pump of a fixed model, which has great limitations. Utility Model Content

[0004] In view of this, the purpose of the utility model is to solve the shortcomings existing in the background technology, and to propose a clamping tool for pump casing processing to solve the problems existing in the prior art.

[0005] In order to achieve the above purpose, the utility model provides a clamping tool for pump casing processing, including a bracket, a guide plate is fixedly connected to the top of the bracket, a slide seat is slidably connected to the outer surface of the guide plate, a clamping jaw is fixedly installed on the top of the slide seat, a step surface is provided on the inner side of the clamping jaw, a rubber layer is provided on the step surface, a storage box is fixedly installed on the top of the guide plate, and a driving mechanism for adjusting the position of the clamping jaw is provided on the bracket.

[0006] Preferably, the driving mechanism includes a motor fixedly installed inside the bracket, and the output end of the motor is fixedly connected to the driving shaft. The two sets of jaws can be synchronously adjusted through the driving mechanism so that the pump casing of the hydraulic pump can be stably clamped during the approach process.

[0007] Preferably, one end of the driving shaft away from the motor is fixedly connected to a rotating frame, and both ends of the rotating frame are rotatably connected to a first connecting shaft.

[0008] Preferably, an outer surface of the first connecting shaft is rotatably connected to an arc plate, and an end of the arc plate away from the first connecting shaft is rotatably connected to the second connecting shaft.

[0009] Preferably, a slide groove is provided on the slide seat, and the inner wall of the slide groove is slidably connected to the outer surface of the guide plate.

[0010] Preferably, a support foot is fixedly connected to the bottom of the slide seat, and the bottom of the support foot is rotatably connected to the outer surface of the second connecting shaft.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The clamping tool for processing the pump casing can synchronously adjust the positions of the two sets of jaws through the driving mechanism, so that the two sets of jaws gradually approach the pump casing during the reverse movement, and finally cooperate with the stepped surface and the rubber layer to clamp the pump casing quickly and stably. The design of the stepped surface and the rubber layer can adapt to hydraulic pump casings of different models and sizes, and is no longer limited to a specific pump casing model, thereby improving the versatility and flexibility of the device.

[0013] 2. The clamping tool for processing the pump casing can clamp the pump casing quickly and stably. The stepped surface and rubber layer on the inner side of the clamping jaws can effectively provide additional friction and buffering effect, ensuring that the pump casing will not slide or shift during processing, thereby ensuring processing quality and safety.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] See also Figure 1-4 A clamping tool for pump casing processing includes a bracket 1, a guide plate 2 is fixedly connected to the top of the bracket 1, a slide seat 3 is slidably connected to the outer surface of the guide plate 2, a clamping jaw 4 is fixedly installed on the top of the slide seat 3, a stepped surface 5 is provided on the inner side of the clamping jaw 4, a rubber layer 6 is provided on the stepped surface 5, a storage box 7 is fixedly installed on the top of the guide plate 2, and a driving mechanism for adjusting the position of the clamping jaw 4 is provided on the bracket 1.

[0021] Through the above technical solution, the device can place the pump casing of the hydraulic pump in the storage box 7 when in use, and can simultaneously move two sets of jaws 4 through the driving mechanism to stably clamp the pump casing. During this process, the stepped surface 5 design of the jaws 4, combined with the rubber layer 6, can stably clamp pump casings of different models.

[0022] Specifically, the driving mechanism includes a motor 8 fixedly disposed inside the bracket 1 , and an output end of the motor 8 is fixedly connected to a driving shaft 9 .

[0023] Through the above technical solution, after the motor 8 is turned on, the driving shaft 9 can be driven to rotate, and then the rotating frame 10 can be linked to rotate.

[0024] Specifically, one end of the driving shaft 9 away from the motor 8 is fixedly connected to the rotating frame 10 , and both ends of the rotating frame 10 are rotatably connected to the first connecting shaft 11 .

[0025] Through the above technical solution, the rotating frame 10 drives the corresponding clamping jaws 4 through the two sets of first connecting shafts 11 and the arc plates 12 and other components.

[0026] Specifically, the outer surface of the first connecting shaft 11 is rotatably connected to the arc plate 12 , and one end of the arc plate 12 away from the first connecting shaft 11 is rotatably connected to the second connecting shaft 13 .

[0027] Through the above technical solution, after the arc plate 12 is pulled, it can drive the supporting leg 15 through the second connecting shaft 13 at the other end.

[0028] Specifically, a slide groove 14 is provided on the slide seat 3 , and the inner wall of the slide groove 14 is slidably connected to the outer surface of the guide plate 2 .

[0029] Through the above technical solution, the design of the slide groove 14 is to allow the slide seat 3 to be completely and stably clamped on the guide plate 2, so that the slide seat 3 can only move horizontally.

[0030] Specifically, a support leg 15 is fixedly connected to the bottom of the slide seat 3 , and the bottom of the support leg 15 is rotatably connected to the outer surface of the second connecting shaft 13 .

[0031] Through the above technical solution, the arc plate 12 drives the support foot 15 through the second connecting shaft 13 and finally acts on the slide seat 3. The support foot 15 and the arc plate 12 are arranged on the same side.

[0032] Working principle: When the device is in use, the pump housing of the hydraulic pump is first placed in the storage box 7, and then the motor 8 is turned on to drive the drive shaft 9 to rotate. During this process, the rotating frame 10 will rotate synchronously with the drive shaft 9, and the two ends of the rotating frame 10 will respectively pull the arc plate 12 on the corresponding side through the first connecting shaft 11. After being pulled, the arc plate 12 will deflect accordingly, and the other end will rotate along the second connecting shaft 13, and drive the support leg 15 through the second connecting shaft 13, thereby pulling the support leg 15, and finally make the two sets of slide seats 3 slide synchronously and in opposite directions along the guide plate 2, that is, the two sets of clamps 4 will cooperate with the stepped surface 5 and the rubber layer 6 designed on the inner side of the clamps 4 to press against the pump housing in the process of approaching each other. The surface is clamped quickly and stably. Since the step surface 5 refers to a series of gradually rising or falling step-like structures on the inner side of the clamping jaw 4, the height and spacing of each group of step surfaces 5 are the same. The design of the step surface 5 enables the clamping jaw 4 to contact different parts of the pump casing and be adaptively adjusted according to the shape and size of the pump casing. The rubber layer 6 is located on the step surface 5, and its function is to provide additional friction and buffering effect on the surface of the pump casing. The rubber layer 6 can increase the stability of clamping, prevent the pump casing from sliding or shifting during the clamping process, and reduce scratches or damage to the surface of the pump casing, protect the appearance and surface quality of the pump casing, and ultimately achieve the effect of stably clamping pump casings of different models.

[0033] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
