Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a production tool suitable for a hydraulic pump cylinder body. Background Art

[0002] The hydraulic pump is the power element of the hydraulic system. It is driven by an engine or an electric motor, sucking oil from the hydraulic oil tank, forming a pressure oil discharge, and sending it to the actuator. Hydraulic pumps are divided into gear pumps, plunger pumps, vane pumps and screw pumps according to their structure. According to whether the flow rate is adjustable, they can be divided into: variable pumps and fixed pumps. The output flow can be adjusted according to needs. It is called a variable pump, and the flow cannot be adjusted. It is divided into three types according to the commonly used pump structure in the hydraulic system: gear pumps, vane pumps and plunger pumps. The cylinder of the hydraulic pump is a key part in the hydraulic pump, and the quality of the product must be guaranteed.

[0003] At present, the prior art CN102380780B discloses a hydraulic pump cylinder processing tool, including: a fixture base, the rear end of which is connected to the machine tool; a hydraulic cylinder body, connected to the fixture base, the inner wall of which is provided with a hydraulic cylinder sleeve; a deformable clamping sleeve for clamping the cylinder workpiece, which is installed in the hydraulic cylinder sleeve. When the process equipment is used, the assembled process equipment is installed on the machine tool after the positioning pin on the fixture base is aligned with the installation hole on the machine tool. During installation, pay attention to the installation position of the process equipment to ensure that the inlet and outlet of the hydraulic oil on the fixture base can be opposite to the hole for providing hydraulic oil on the machine tool. After installation, the workpiece is placed in the hole of the deformable clamping sleeve, the machine tool oil pump is started, and the hydraulic oil is obtained from the machine tool itself in a short time before the machine tool works. The hydraulic oil fills the cavity between the hydraulic cylinder body and the hydraulic cylinder sleeve. When the pressure of the hydraulic oil reaches the specified value, the deformation is transmitted to the deformable clamping sleeve through the deformation of the hydraulic cylinder sleeve. Finally, the purpose of clamping the workpiece is achieved by contracting the deformed clamping sleeve. After the parts are processed, the machine oil pump is turned off, the delivery of hydraulic oil is stopped, the pressure between the cylinder body and the inner sleeve of the hydraulic cylinder disappears, the deformation of the inner sleeve of the hydraulic cylinder and the deformed clamping sleeve is restored, and the clamping force of the parts disappears. At this time, the processed parts are taken out and the processing is completed. The present invention makes the workpiece evenly stressed on the outer circumferential surface, eliminates the deformation of the workpiece caused by clamping the workpiece, and fundamentally guarantees the accuracy of the processed parts. The process equipment overcomes the defects of the existing processing technology, fundamentally guarantees the accuracy of the parts, improves production efficiency, and reduces production costs.

[0004] The above technology requires that the cylinder body be mounted and fixed on a fixture base before processing the cylinder body. However, the above fixture base can only fix cylinder bodies of a single diameter and cannot fix cylinder bodies of different sizes before processing, so its use is relatively limited.

DETAILED DESCRIPTION

[0019] The first embodiment of the present application is:

[0020] See also Figure 1 , Figure 1It is a structural schematic diagram of the utility model, including a base 101 and an adjusting fixture 102, the adjusting fixture 102 includes a sliding plate 103, a fixing member 104 and a clamping plate 105; the base 101 has a slide groove 106, the fixing member 104 includes a rotating bolt 107, a knob 108 and a clamping ring 109, and the clamping plate 105 includes an arc-shaped clamping plate 110 and a soft rubber pad 111. The above-mentioned scheme solves the problem that the production tooling of the existing hydraulic pump cylinder body can only fix the cylinder body of a single diameter and has a relatively limited use. It can be understood that the above-mentioned scheme can be used in the scenario of hydraulic pump processing and production.

[0021] According to this specific embodiment, the adjusting fixture 102 is arranged on one side of the base 101, the sliding plate 103 is slidably connected to the base 101 and is located on the top of the base 101, the fixing member 104 is arranged on one side of the sliding plate 103, the clamping plate 105 is fixedly connected to the sliding plate 103 and is located on the side of the sliding plate 103 away from the base 101, the base 101 provides installation conditions for the adjusting fixture 102, the sliding plate 103 can slide on the base 101 by itself, so as to adjust the spacing between the clamping plates 105, thereby making the The clamping plate 105 can clamp and fix cylinder bodies of different diameters. The setting of the fixing piece 104 is used to fix the sliding plate 103 on the base 101 to prevent the sliding plate 103 from sliding and causing the clamping plate 105 to loosen during cylinder body processing, thereby affecting the fixing effect of the tooling. The adjusting fixture 102 can be adjusted according to the fixed cylinder body to be processed, so that it is suitable for fixing cylinder bodies of different diameters. Compared with the traditional fixed base with a fixed diameter, it is more practical and solves the problem that the existing production tooling of hydraulic pump cylinder bodies can only fix cylinder bodies of a single diameter and is of limited use.

[0022] The slide groove 106 is located at one side of the base 101 , and the slide groove 106 is used to limit the sliding plate 103 to prevent the sliding plate 103 from deviating and causing the clamping plate 105 to deviate sideways when a worker slides the sliding plate 103 .

[0023] Secondly, the rotating bolt 107 is threadedly connected to the sliding plate 103 and penetrates the sliding plate 103. The knob 108 is fixedly connected to the rotating bolt 107 and is located on the side of the rotating bolt 107 away from the sliding plate 103. The clamping ring 109 is fixedly connected to the rotating bolt 107 and is located on the side of the rotating bolt 107 away from the knob 108. The rotating bolt 107 is a fixed bolt. The setting of the knob 108 makes it easy for workers to rotate the rotating bolt 107 and improves practicality. The clamping ring 109 is used to firmly press the base 101, thereby fixing the sliding plate 103. It is fixed on the base 101 to fix the clamping plate 105. Specifically, when fixing the sliding plate 103, the worker turns the knob 108 by hand. Under the action of the knob 108, the rotating bolt 107 rotates. The rotating bolt 107 rotates under the action of the thread, which is equivalent to the movement of the sliding plate 103. The moving bolt moves down into the slide groove 106 until the clamping ring 109 on the rotating bolt 107 presses the base 101. The worker stops turning the knob 108, and the fixing of the sliding plate 103 is completed.

[0024] At the same time, the arc-shaped clamping plate 110 is fixedly connected to the sliding plate 103 and is located on the side of the sliding plate 103 away from the base 101. The soft rubber pad 111 is fixedly connected to the arc-shaped clamping plate 110 and is located on one side of the arc-shaped clamping plate 110. The setting of the arc-shaped clamping plate 110 is used to provide clamping force from all sides of the cylinder body to be processed, and fix the cylinder body on the base 101. The setting of the soft rubber pad 111 reduces the gap between the arc-shaped clamping plate 110 and the cylinder body, and improves the fixing effect of the arc-shaped clamping plate 110 on the cylinder body.

[0025] To fix the cylinder body to be processed, the worker first slides the sliding plate 103 away from the center of the base 101 with his hands, and then places the cylinder body to be processed between the arc-shaped clamping plates 110. At this time, the worker pushes the arc-shaped clamping plate 110 toward the side close to the cylinder body with his hands, so that the soft rubber pad 111 on one side of the arc-shaped clamping plate 110 firmly presses against the cylinder body, and turns the knob 108 with his hands. Under the action of the knob 108, the rotating bolt 107 rotates. The rotation of the rotating bolt 107 under the action of the thread makes the rotating bolt 107 equivalent to the movement of the sliding plate 103. The rotating bolt 107 moves down into the slide groove 106 until the clamping ring 109 on the rotating bolt 107 presses the base 101. The worker stops turning the knob 108 to complete the fixation of the sliding plate 103, thereby completing the limited fixation of the cylinder body.

[0026] The second embodiment of the present application is:

[0027] Based on the first embodiment, please refer to Figure 2-Figure 3 , Figure 2 It is a structural schematic diagram of the utility model. Figure 3 It is a schematic diagram of the fixing member fixing the sliding plate of the utility model. The production tooling suitable for the hydraulic pump cylinder body of this embodiment also includes an auxiliary component 201, and the auxiliary component 201 includes a pull ring 202 and a friction pad 203.

[0028] According to this specific embodiment, the auxiliary component 201 is respectively arranged on one side of the arc-shaped clamping plate 110 and the clamping ring 109. The arrangement of the auxiliary component 201 facilitates the use of the arc-shaped clamping plate 110 and the clamping ring 109, thereby improving the practicality of the tooling.

[0029] Among them, the pull ring 202 is fixedly connected to the arc-shaped clamping plate 110 and is located on one side of the arc-shaped clamping plate 110, and the friction pad 203 is fixedly connected to the clamping ring 109 and is located at the bottom of the clamping ring 109. The setting of the pull ring 202 is convenient for workers to pull the arc-shaped clamping plate 110, so that the sliding plate 103 slides in the sliding groove 106 of the base 101. The setting of the friction pad 203 is used to increase the friction between the clamping ring 109 and the base 101, thereby improving the fixing effect of the clamping ring 109 on the sliding plate 103.

[0030] When the auxiliary component 201 is in use, the worker holds the pull ring 202 with his hand and pulls the arc-shaped clamping plate 110 through the pull ring 202, so that the sliding plate 103 slides in the sliding groove 106 of the base 101, and the clamping ring 109 slides down to drive the friction pad 203 to move down until the clamping ring 109 firmly presses the friction pad 203 against the base 101, thereby increasing the friction between the clamping ring 109 and the base 101, and improving the fixing effect of the clamping ring 109 on the sliding plate 103.

[0031] The above disclosure is only a preferred embodiment of the production tooling suitable for the hydraulic pump cylinder body of the present application, and cannot be used to limit the scope of rights of the present application.
