Description

Technical Field

[0001] The utility model relates to the field of unit pumps, in particular to a positioning tooling for unit pumps. Background Art

[0002] A unit pump is a device used to generate the injection pressure of an injector. It is an important part of a hydraulic system and is widely used in various mechanical equipment. The positioning tooling for unit pumps is a tool device used to ensure the precise positioning and fixation of unit pumps during the processing or assembly process.

[0003] In actual production, the surface shapes of unit pumps are diverse, including both flat surfaces and arc surfaces, and even flat surfaces and arc surfaces coexist on the same pump body, which poses great challenges to the design of the positioning tooling for unit pumps.

[0004] Most of the current unit pump positioning toolings on the market are designed for unit pumps with specific shapes or sizes, lacking universality and flexibility. When facing unit pumps with different surface shapes (such as flat surfaces, arc surfaces or mixed surfaces), the existing toolings are often difficult to adapt, resulting in inaccurate positioning and low processing efficiency. Due to the complexity of the surface shapes of unit pumps, traditional positioning toolings are difficult to provide stable support and precise positioning, making it easy to generate vibration and displacement during the processing, thereby affecting the processing accuracy. For unit pumps with different shapes, it is necessary to frequently replace or adjust the positioning tooling, increasing the operation difficulty and time cost. Summary of the Utility Model

[0005] To solve the above-mentioned problems, the utility model is realized through the following technical solutions:

[0006] A positioning tooling for unit pumps, comprising: a positioning seat for providing a space for positioning the unit pump; a pump body disposed on the positioning seat; a plurality of positioning mechanisms mounted on the positioning seat and configured to move simultaneously closer to or away from the center of the positioning seat for positioning the pump body; each positioning mechanism comprising: a moving seat mounted on the positioning seat; a rotating seat mounted on the moving seat and configured to rotate on the moving seat for switching different positioning heads; a plurality of positioning heads mounted on the rotating seat and distributed in a circumferential array, and the plurality of positioning heads are configured to rotate together with the rotating seat for positioning different pump bodies.

[0007] Each positioning mechanism further comprises: a connecting groove formed on the moving seat, and the rotating seat is connected in the connecting groove.

[0008] The positioning seat comprises: a positioning groove formed at one end of the positioning seat, and the pump body is disposed in the positioning groove; a plurality of control grooves formed on the outer circle of the positioning seat and distributed in a circumferential array, and one end of the moving seat penetrates through the control groove and extends into the positioning groove.

[0010] It further includes: an elastic member, one end of which is connected to the inner wall of the control groove and the other end is connected to the bevel seat, and the elastic member is used to provide an initial position restoring force for the bevel seat.

[0011] It further includes: a power source, which is installed on the positioning seat, the power shaft of the power source is connected to the control seat, and the power source is used to provide moving power for the control seat.

The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0032] Refer to Figures 1 - 6, A positioning tooling for a unit pump, comprising: a positioning seat 1 for providing a space to position the unit pump; a pump body 2 disposed on the positioning seat 1; several positioning mechanisms 5 installed on the positioning seat 1 and configured to move simultaneously towards or away from the center of the positioning seat 1 for positioning the pump body 2; the positioning mechanism 5 includes: a moving seat 501 installed on the positioning seat 1; a rotating seat 503 installed on the moving seat 501 and configured to rotate on the moving seat 501 for switching different positioning heads 504; several positioning heads 504 installed on the rotating seat 503 and distributed in a circumferential array, the several positioning heads 504 being configured to rotate together with the rotating seat 503 for positioning different pump bodies 2, and the several positioning heads 504 having different shapes for adapting to the surfaces of pump bodies 2 with different shapes; a connecting groove 502 opened on the moving seat 501, and the rotating seat 503 is connected in the connecting groove 502. The tooling is equipped with multiple positioning heads 504 with different shapes, which are distributed in a circumferential array on the rotating seat 503 and can be easily switched through the rotating seat 503. This design enables the tooling to quickly adapt to the surfaces of pump bodies 2 with different shapes (such as flat surfaces, arc surfaces or mixed surfaces), greatly improving the versatility and flexibility of the tooling; through the simultaneous action of several positioning mechanisms 5, the tooling can ensure that the pump body 2 is firmly and accurately positioned on the positioning seat 1. The designs of the moving seat 501 and the rotating seat 503 in the positioning mechanism 5 allow the positioning heads 504 to precisely adjust their positions in three-dimensional space, achieving all-round and dead-angle-free positioning of the pump body 2, not only improving the machining accuracy, but also effectively reducing the vibration and displacement during the machining process, ensuring the stability of the machining quality.

[0033] Refer to Figure 4 and Figure 5 , the positioning seat 1 includes: a positioning groove 101 opened at one end of the positioning seat 1, and the pump body 2 is disposed in the positioning groove 101; several control grooves 102 opened on the outer circle of the positioning seat 1 and distributed in a circumferential array, and one end of the moving seat 501 penetrates through the control groove 102 and extends into the positioning groove 101.

[0034] Refer to Figure 4 and Figure 5, a control seat 3 is installed on the positioning seat 1 and is configured to move on the positioning seat 1. It is used to control the simultaneous movement of several positioning seats 1 when moving. The control seat 3 is in a circular ring shape; several extrusion seats 301 are installed on the control seat 3. The extrusion seats 301 are arranged in the control grooves 102. One end of the extrusion seat 301 is formed with an inclined surface; several hypotenuse seats 302 are respectively installed in several control grooves 102. The inclined surface of the extrusion seat 301 is in contact with the hypotenuse of the hypotenuse seat 302. The moving seat 501 is connected to the inclined surface seat; an elastic member 303 has one end connected to the inner wall of the control groove 102 and the other end connected to the hypotenuse seat 302. The elastic member 303 is used to provide an initial position restoring force for the hypotenuse seat 302; a power source 4 is installed on the positioning seat 1. The power shaft of the power source 4 is connected to the control seat 3. The power source 4 is used to provide moving power for the control seat 3; integrating automation components such as the power source 4 and the control seat 3 enables the entire positioning process to be automated through external control. The power source 4 provides moving power for the control seat 3, and the control seat 3 controls the movement of multiple positioning mechanisms 5 simultaneously through the interaction of the extrusion seat 301 and the hypotenuse seat 302. This design not only simplifies the operation process but also significantly improves work efficiency and reduces errors and costs caused by manual operation. The power source 4 can be a cylinder or a linear motor, and the elastic member 303 can be a stainless steel spring or a rubber elastic block.

[0035] During the use process, the tooling is in a standby state. All the moving seats 501 and rotating seats 503 in the positioning mechanism 5 are in their initial positions. According to the shape and positioning requirements of the pump body 2, the appropriate-shaped positioning head 504 is selected by rotating the rotating seat 503. The rotating seat 503 rotates on the moving seat 501, and the pump body 2 to be positioned is placed in the positioning groove 101 on the positioning seat 1 to ensure that the pump body 2 is stable and in the correct position. Then, the power source 4 is activated, and the power shaft starts to rotate or move linearly, pushing the control seat 3 to move on the positioning seat 1. The movement of the control seat 3 drives the extrusion seat 301 to slide in the control groove 102. The inclined surface of the extrusion seat 301 interacts with the hypotenuse of the hypotenuse seat 302 to generate a horizontal thrust. Since the extrusion seat 301 is connected to the moving seat 501, this thrust causes the moving seat 501 to move simultaneously towards the center of the positioning seat 1, driving the positioning head 504 to approach the pump body 2. The hypotenuse seat 302 squeezes the elastic member 303, and the positioning head 504 gradually approaches the surface of the pump body 2 until it contacts the pump body 2 and applies an appropriate pressure to ensure the complete fit and precise positioning of the positioning head 504 with the surface of the pump body 2. When all the positioning heads 504 firmly and accurately position the pump body 2, the positioning process is completed. At this time, the pump body 2 is stably fixed on the positioning seat 1, ready for subsequent processing or assembly operations. The entire positioning process can be automated through an external control system. The control system can adjust the position and force of the positioning head 504 according to a preset program or a signal feedback in real time to adapt to the positioning requirements of different pump bodies 2. When the processing or assembly is completed, the power source 4 runs in the reverse direction, and the control seat 3 drives the extrusion seat 301 to move in the reverse direction, releasing the thrust on the moving seat 501. Under the action of the elastic member 303, the moving seat 501 and the positioning head 504 automatically return to their initial positions, ready for the next positioning operation.

[0036] In summary, compared with the prior art, the following beneficial effects are achieved:

[0037] By designing multiple positioning heads 504 with different shapes and arranging them in a circumferential array on the rotating seat 503, rapid adaptation to single pumps with different shapes (such as flat surfaces, arc surfaces, or mixed surfaces) is achieved. The design of the rotating seat 503 allows users to easily switch different-shaped positioning heads 504 without replacing the entire tooling, improving the versatility and flexibility of the tooling and meeting the diverse production requirements.

[0038] Through the simultaneous action of several positioning mechanisms 5, this solution can ensure that the pump body 2 is firmly and accurately positioned on the positioning seat 1. The design of the moving seat 501 and the rotating seat 503 in the positioning mechanism 5 allows the positioning head 504 to precisely adjust its position in three-dimensional space, achieving all-round and dead-angle-free positioning of the pump body 2. This not only improves the processing accuracy but also effectively reduces vibration and displacement during the processing, ensuring the stability of the processing quality.

[0039] Automation components such as the power source 4 and the control base 3 are integrated, enabling the entire positioning process to be automated through external control. The power source 4 provides the moving power for the control base 3, and the control base 3 controls the movement of multiple positioning mechanisms 5 simultaneously through the interaction between the extrusion base 301 and the hypotenuse base 302, simplifying the operation process, significantly improving work efficiency, and reducing errors and costs caused by manual operation.
