Description

Technical Field

[0001] This utility model relates to the field of oil pump assembly technology, and in particular to a jig for assembling oil pumps. Background Technology

[0002] A jig is a broad category of tools used in woodworking, metalworking, fitter work, machinery, electrical control, and other handicrafts. It is primarily used to assist in controlling position or movement.

[0003] In the existing oil pump assembly process, the various parts of the oil pump are placed on the corresponding fixtures manually, and the screws are tightened.

[0004] However, during the assembly of the oil pump, if the parts are not placed in the correct position or if the parts shift due to stress during assembly, the tightening torque value will be unstable (resulting in a lower quality oil pump assembly). This requires readjusting the placement of the parts and re-tightening, which reduces work efficiency. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the technical problem solved by this utility model is: how to improve the working efficiency of oil pump assembly.

[0006] To achieve the above objectives, the present invention provides a fixture for assembling an oil pump, comprising: Base; The first positioning component is fixedly mounted on the base and is used to position the first part. The first clamping assembly is fixedly mounted on the base and is used to limit the first part. The second positioning component is fixedly mounted on the base and is used to position the second part. The second clamping assembly is fixedly mounted on the base and is used to limit the second part.

[0007] By adopting the above technical solution, during the oil pump assembly process, the first part is placed in a preset position on the top surface of the base using the first positioning component, and the second part is placed in a preset position on the top surface of the base using the second positioning component. After the first and second parts are placed, the first part is pressed down using the first clamping component, making the first part relatively stationary with respect to the base. The second part is then pressed down using the second clamping component, making the second part relatively stationary with respect to the base. Therefore, the first and second parts are relatively stationary. Finally, the screws are tightened manually. Thus, this fixture solves the problem of unstable tightening torque values ​​caused by parts not being placed in the correct position during the placement process or parts shifting due to force during assembly, thereby improving the working efficiency of oil pump assembly.

[0008] In one embodiment, the base includes a placement plate, support frames, and a protective cover. Multiple support frames are arranged along the circumference of the bottom of the placement plate, and a protective cover is arranged between two adjacent support frames. The placement plate, support frames, and protective cover surround to form a receiving cavity.

[0009] By adopting the above technical solution, each component in the fixture is installed on the placement plate, and the resulting receiving cavity can accommodate mechanical structures such as cables and air pipes, thus avoiding any impact on the assembly work.

[0010] In one embodiment, the first positioning component includes a step positioning pin, an auxiliary support frame, and a support column. The step positioning pin, the auxiliary support frame, and the support column are all fixedly disposed on the top surface of the base, and the three are distributed in a triangle on the top surface of the base.

[0011] By adopting the above technical solution, a stable support is provided for the first part, and the above structure is aligned with the structure on the first part, thereby playing a positioning role and further improving the positioning accuracy.

[0012] In one embodiment, the first positioning component further includes a positioning post, a sensor bracket, and a first position sensor. The positioning post is fixedly disposed on the top surface of the base, and the first position sensor is disposed on the positioning post through the sensor bracket. The first position sensor is used to detect the positional relationship between the first part and the step positioning pin, the auxiliary support frame, and the support post.

[0013] By adopting the above technical solution, it is easier to observe and judge whether the first part is aligned with the step positioning pin, auxiliary support frame and support column, thereby further improving the positioning accuracy.

[0014] In one embodiment, the first clamping assembly includes a first cylinder, a bracket, a connecting rod, a pressure arm, and a pressure head. The first cylinder is fixedly disposed on the top surface of the base, the bracket is disposed on the top surface of the first cylinder, the bracket is hinged to the side of the pressure arm through the connecting rod, one end of the pressure arm is hinged to the telescopic end of the first cylinder, and the other end of the pressure arm is fixed with a pressure head, which is used to clamp the first part.

[0015] By adopting the above technical solution, the pressing angle and pressing force of the pressure head can be adjusted through the output end of the first cylinder, thereby adapting to the clamping operation of parts of different heights. Therefore, the above design improves the applicability of the fixture.

[0016] In one embodiment, a first magnetic proximity switch is provided on the first cylinder, which is used to detect the position of the pressure head.

[0017] By adopting the above technical solution, it is convenient to detect the clamping and loosening state of the first part.

[0018] In one embodiment, the second positioning component includes a contour jig and a second position sensor. The contour jig includes a boss and a vertical surface. The vertical surface is arranged in a ring on the top surface of the base. The top surface of the vertical surface is provided with a plurality of bosses. The bosses are used to limit the second part. The second position sensor is disposed on the top surface of the base located inside the vertical surface. The second position sensor is used to detect the positional relationship between the second part and the bosses.

[0019] By adopting the above technical solution, a stable support is provided for the second part, and by aligning the above structure with the structure on the second part, the horizontal movement of the second part is restricted, thereby playing a positioning role and further improving the positioning accuracy; the second position sensor facilitates observation and judgment of whether the second part is connected with the boss, thereby further improving the positioning accuracy.

[0020] In one embodiment, the second clamping assembly includes a second cylinder and a wedge. The second cylinder is fixedly disposed on the top surface of the base, and the wedge is fixedly disposed on the telescopic end of the second cylinder. The wedge is used to clamp the second part.

[0021] By adopting the above technical solution, the extension and retraction length of the wedge can be adjusted through the output end of the second cylinder, thereby adjusting the pressure on the second part. This allows it to be adapted to clamping operations of parts of different widths, thus improving the applicability of the fixture.

[0022] In one embodiment, a second magnetic proximity switch is provided on the second cylinder, which is used to detect the position of the wedge.

[0023] By adopting the above technical solution, it is convenient to detect the clamping and loosening state of the second part.

[0024] In one embodiment, a reflector is provided on the top surface of the base, which is used to reflect the QR code on the second part.

[0025] By adopting the above technical solution, it is easy to reflect the QR code image on the part, thereby avoiding the inability to scan the code because the part is fixed on the fixture.

[0026] In summary, this utility model has at least one of the following beneficial technical effects: 1. During the oil pump assembly process, the first part is placed in a preset position on the top surface of the base using the first positioning component, and the second part is placed in a preset position on the top surface of the base using the second positioning component. After the first and second parts are placed, the first part is pressed down using the first clamping component, making the first part relatively stationary with respect to the base. The second part is then pressed down using the second clamping component, making the second part relatively stationary with respect to the base. Therefore, the first and second parts are relatively stationary. Finally, the screws are tightened manually. Thus, this fixture solves the problem of unstable tightening torque caused by improper placement of parts during the assembly process or by parts shifting due to force, thereby improving the efficiency of oil pump assembly. 2. The specific design of the first and second positioning components improves the accuracy of the placement of parts on the fixture, thereby avoiding subsequent adjustments and further improving work efficiency; 3.

Detailed Implementation

[0028] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0029] The jig for assembling the oil pump in this embodiment of the invention is shown in [reference]. Figure 1 The jig for assembling the oil pump includes a base 1; a first positioning component 2, which is fixedly disposed on the base 1 and is used to position a first part 7; a first clamping component 3, which is fixedly disposed on the base 1 and is used to limit the first part 7; a second positioning component 4, which is fixedly disposed on the base 1 and is used to position a second part 8; and a second clamping component 5, which is fixedly disposed on the base 1 and is used to limit the second part 8.

[0030] Therefore, in the oil pump assembly process of this utility model, the first part 7 is placed on the preset position on the top surface of the base 1 by the first positioning component 2, and the second part 8 is placed on the preset position on the top surface of the base 1 by the second positioning component 4. After the first part 7 and the second part 8 are placed, the first part 7 is pressed by the first pressing component 3, and the first part 7 is relatively stationary with respect to the base 1. The second part 8 is pressed by the second pressing component 5, and the second part 8 is relatively stationary with respect to the base 1. Therefore, the first part 7 and the second part 8 are relatively stationary. Finally, the screws are tightened manually. Therefore, this fixture solves the problem that the parts are not placed in the correct position during the placement process, or that the parts are offset due to force during the assembly process, resulting in unstable tightening torque values, thereby improving the working efficiency of oil pump assembly.

[0031] Preferred, see Figure 2 As shown, a specific structure of a base 1 is provided: The base 1 includes a placement plate 101, a support frame 103 and a protective cover 102. Multiple support frames 103 are provided along the perimeter of the bottom of the placement plate 101. A protective cover 102 is provided between two adjacent support frames 103. The placement plate 101, the support frame 103 and the protective cover 102 surround each other to form a receiving cavity.

[0032] Specifically, the placement plate 101 is supported by multiple support frames 103, and a protective cover 102 is provided between two adjacent support frames 103, so that the three form a receiving cavity with an opening at the bottom. After other structures in the fixture are placed on the placement plate 101, such as the cables and air pipes in the cylinder and sensor, they can be placed inside the receiving cavity to avoid placing them on the placement plate 101 and to avoid affecting the assembly work.

[0033] Preferred, see Figure 2 As shown, a specific structure of the first positioning component 2 is provided: The first positioning component 2 includes a step positioning pin 201, an auxiliary support frame 202, and a support column 203. The step positioning pin 201, the auxiliary support frame 202, and the support column 203 are all fixedly installed on the top surface of the base 1, and the three are distributed in a triangle on the top surface of the base 1.

[0034] Specifically, the step positioning pin 201, auxiliary support frame 202 and support column 203 are fixedly installed in a triangular arrangement on the top surface of the base 1. The top surfaces of the three are supported and positioned with the preset points of the first part 7, providing stable support for the first part 7. Furthermore, the above structure is aligned with the structure on the first part 7, thereby playing a positioning role and further improving the positioning accuracy.

[0035] Furthermore, the first positioning component 2 also includes a positioning post 204, a sensor bracket 205, and a first position sensor 206. The positioning post 204 is fixedly disposed on the top surface of the base 1, and the first position sensor 206 is disposed on the positioning post 204 through the sensor bracket 205. The first position sensor 206 is used to detect the positional relationship between the first part 7 and the step positioning pin, the auxiliary support frame 202, and the support post 203.

[0036] Specifically, the sensor bracket 205 is supported by the positioning column 204, and the first position sensor 206 is installed on the sensor bracket 205. The sensor bracket 205 can rotate around the positioning column 204 to change the position of the first position sensor 206, thereby making it easier to observe and determine whether the first part 7 is aligned with the step positioning pin 201, the auxiliary support frame 202 and the support column 203, thereby further improving the positioning accuracy.

[0037] Preferred, see Figure 3 As shown, a specific structure of a first clamping component 3 is provided: The first clamping assembly 3 includes a first cylinder 301, a bracket 302, a connecting rod 306, a pressure arm 303, and a pressure head 304. The first cylinder 301 is fixedly mounted on the top surface of the base 1. The bracket 302 is mounted on the top surface of the first cylinder 301. The bracket 302 is hinged to the side of the pressure arm 303 via the connecting rod 306. One end of the pressure arm 303 is hinged to the telescopic end of the first cylinder 301. The other end of the pressure arm 303 is fixed with a pressure head 304, which is used to clamp the first part 7.

[0038] Specifically, when the output end of the first cylinder 301 extends upward, it drives one end of the pressure arm 303 to move upward, thereby causing the other end with the pressure head 304 to move downward. When the output end of the first cylinder 301 retracts downward, the movement direction of the pressure head 304 is reversed. Therefore, the downward pressing angle and downward pressure of the pressure head 304 can be adjusted by the output end of the first cylinder 301, thus adapting to the clamping operation of parts of different heights. Therefore, the above design improves the applicability of the fixture.

[0039] Furthermore, a first magnetic proximity switch 305 is provided on the first cylinder 301, which is used to detect the position of the pressure head 304.

[0040] Specifically, a magnetic proximity switch is a type of proximity switch, which is one of many types in the sensor family. It is a position sensor that uses the electromagnetic working principle and is made with advanced technology. It can convert non-electrical or electromagnetic quantities into desired electrical signals by changing the positional relationship between the sensor and the object, thereby achieving the purpose of control or measurement. Therefore, it can detect the positional relationship between the pressure head 304 and the first part 7, thereby detecting the pressing and releasing state of the first part 7.

[0041] Preferred, see Figure 4 As shown, a specific structure of a second positioning component 4 is provided: The second positioning component 4 includes a contour jig and a second position sensor 403. The contour jig includes a boss 401 and a face 402. The face 402 is arranged in a ring on the top surface of the base 1. The top surface of the face 402 is provided with a plurality of bosses 401. The bosses 401 are used to limit the second part 8. The second position sensor 403 is located on the top surface of the base 1 inside the face 402. The second position sensor 403 is used to detect the positional relationship between the second part 8 and the bosses 401.

[0042] Specifically, the facade 402 provides stable support for the second part 8. The annular facade 402 is divided into multiple areas by the boss 401. Each area corresponds to a different preset point on the second part 8. The preset point of the second part 8 is aligned with the different areas, and the horizontal movement of the second part 8 is restricted by the boss 401, thereby playing a positioning role and further improving the positioning accuracy. The second position sensor 403 facilitates observation and judgment of whether the second part 8 is connected to the boss 401, thereby further improving the positioning accuracy.

[0043] Preferred, see Figure 5 As shown, a specific structure of a second clamping component 5 is provided: The second clamping assembly 5 includes a second cylinder 501 and a wedge 502. The second cylinder 501 is fixedly disposed on the top surface of the base 1, and the wedge 502 is fixedly disposed on the telescopic end of the second cylinder 501. The wedge 502 is used to clamp the second part 8.

[0044] Specifically, by adjusting the extension and retraction length of the wedge block 502 through the output end of the second cylinder 501, the pressure on the second part 8 is adjusted, thereby adapting to the clamping operation of parts of different widths. Therefore, the above design improves the applicability of the fixture.

[0045] Furthermore, a second magnetic proximity switch 503 is provided on the second cylinder 501, which is used to detect the position of the wedge block 502.

[0046] Specifically, the clamping and loosening states of the second part 8 are detected.

[0047] Preferred, see Figure 2 As shown, a reflector 6 is provided on the top surface of the base 1. The reflector 6 is used to reflect the QR code on the second part 8.

[0048] Specifically, it facilitates the reflection of QR code images on parts, thus avoiding the inability to scan codes when parts are fixed to fixtures.

[0049] Preferred, see Figure 6 As shown, both the first clamping component 3 and the second clamping component 5 are provided with a housing 9 to prevent parts from colliding with it during placement, which could damage the clamping components and prevent them from working properly.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
