[0005] Preferably, auxiliary support blocks are symmetrically arranged between the second fixing block and the first fixing block. The auxiliary support blocks are connected to the mounting base by fasteners to assist in supporting the plunger pump swing frame. This ensures the positioning accuracy of the plunger pump swing frame during the processing, thereby improving the processing quality of the plunger pump swing frame, increasing processing efficiency and accuracy, and reducing scrap rate and rework rate.

[0010] Preferably, the bottom of the drive device is connected to the base plate via a mounting bracket to ensure the stability of the drive device.

[0011] Preferably, handles are provided at both ends of the upper side of the base plate for easy handling.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] With its simple structure and convenient operation, the dual-station design improves production efficiency and more effectively secures the plunger pump rocker frame, reducing vibration and displacement during processing and significantly enhancing its machining stability. The inclusion of slide rails and a drive mechanism simplifies and speeds up the adjustment of the plunger pump rocker frame's position and angle, greatly reducing operator adjustment time and increasing production efficiency. This design effectively solves the problems of existing plunger pump rocker frame fixing devices that are prone to vibration or loosening during processing, leading to positional shifts, reduced machining accuracy, and low yield rates.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figure 1-6 As shown, this utility model addresses the problem that existing plunger pump rocker frame fixing devices are prone to vibration or loosening during processing, leading to positional displacement of the plunger pump rocker frame, affecting processing accuracy, and resulting in a low pass rate. The following technical solution is provided: A fixing device for planar processing of a plunger pump rocker frame includes a base plate 1, with two symmetrical processing stations 2 arranged on the upper side of the base plate 1. Each processing station 2 includes a mounting base 3 and a support block 4 disposed on the upper side of the base plate 1, opposite to each other on the upper side of the mounting base 3; a first fixing block 5 disposed on the upper side of the mounting base 3; a second fixing block 6 adjustablely disposed on the upper side of the mounting base 3, the space between the second fixing block 6 and the first fixing block 5 used to clamp the plunger pump rocker frame 7; a driving device 8 disposed on the side of the second fixing block 6 to drive its movement; and a positioning pin 15 disposed in the middle of the upper side of the mounting base 3.

[0024] In this embodiment, as Figure 4 As shown, auxiliary support blocks 9 are symmetrically arranged between the second fixing block 6 and the first fixing block 5. The auxiliary support blocks 9 are connected to the mounting base 3 by fasteners 10, which assist in supporting the plunger pump swing frame 7. This ensures the positioning accuracy of the plunger pump swing frame during the processing, thereby improving the processing quality of the plunger pump swing frame, increasing processing efficiency and accuracy, and reducing scrap rate and rework rate.

[0025] In this embodiment, as Figure 1 and Figure 4 As shown, a spring 11 is sleeved on the auxiliary fastener 10. The spring 11 abuts against the second fixing block 6 and the mounting base 3. During processing, the spring 11 has a buffering effect.

[0026] In this embodiment, as Figure 5 As shown, the mounting base 3 is provided with a slot 31 that matches the support block 4, which is used to fix the position of the support block 4.

[0027] In this embodiment, as Figure 3 As shown, the bottom of the second fixing block 6 is provided with a slide rail 12, which facilitates the sliding and positioning of the second fixing block 6 on the mounting base 3.

[0028] In this embodiment, as Figure 6 As shown, the second fixing block 6 and the first fixing block 5 are both provided with protrusions 61 on their respective inner sides. The protrusions 61 are provided with anti-slip textures for clamping the plunger pump swing frame 7.

[0029] In this embodiment, as Figure 3 As shown, the bottom of the drive device 8 is connected to the base plate 1 via a mounting bracket 13 to ensure the stability of the drive device 8.

[0030] In this embodiment, as Figure 2 As shown, handles 14 are provided at both ends of the upper side of the base plate 1 for easy handling.

[0031] In this embodiment, as Figure 1 As shown, in actual use, the operator places the plunger pump swing frame 7 on the support block 4, inserts the positioning pin 15 into the positioning hole of the plunger pump swing frame 7, and one end of the plunger pump swing frame 7 abuts against the first fixing block 5. The second fixing block 6 is driven to move by the driving device 8, so that the second fixing block 6 presses against the side of the plunger pump swing frame 7 and fixes the plunger pump swing frame 7. During processing, the auxiliary support block 9 and the spring 11 provide additional support and cushioning to prevent vibration during processing.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
