Description

Technical Field

[0001] This utility model relates to the field of pump body processing, specifically a pump body casting processing device with upper and lower dual-station configuration, wherein the upper station vertically clamps the pump body casting and the lower station horizontally clamps the pump body casting. Background Technology

[0002] A plunger pump is a crucial component of a hydraulic system. It relies on the reciprocating motion of a plunger within a cylinder to change the volume of the sealed working chamber, thus achieving oil suction and pressure. Plunger pumps offer advantages such as high rated pressure, compact structure, high efficiency, and convenient flow rate adjustment. However, the pump body is characterized by its complex shape and uneven surface. After casting, the surrounding planes and holes require machining. Current machining methods typically employ single-station fixtures to hold the pump body, which can only secure a single pump. With advancements in production technology and the increasing number of production lines, single-station fixtures are no longer sufficient to meet the processing demands of modern production lines. Utility Model Content

[0003] The technical problem to be solved by this utility model is: how to provide a pump body casting processing device with upper and lower dual-station configuration for efficient processing and production of pump body castings, which is used for vertical clamping of pump body castings at the upper station and horizontal clamping of pump body castings at the lower station, and rationally utilizes space.

[0004] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this utility model, which adopts the following technical solution:

[0005] The upper and lower dual-station pump body casting processing device includes a first fixture, a pallet assembly, and a second fixture. The first fixture and the second fixture are distributed vertically. A holding structure is set on the pallet assembly, and the second fixture is located at the tail of the pallet assembly.

[0006] The pump body is placed on the tray assembly and clamped at two fixtures using the tray assembly. The end face holes are then machined (drilled and milled). At the same time, the pump body at the top, which is fixed by fixture one, is also machined with holes of the same specifications. After machining, the lower pump body is installed at fixture one for machining (drilling, milling, and milling the circumferential surface), thus saving on the machining of structures of the same specifications.

[0007] In the pump body dual-station processing device, the first fixture includes a positioning block, a floating support, and a clamping cylinder.

[0008] In the pump body dual-station processing device, the tray assembly includes a slide rail and a stop block 2 located at the end of the slide rail. A slider is slidably fitted on the slide rail, and a sliding plate is installed on the top of the slider.

[0009] The mounting structure includes a first upright, a second upright, a second floating support, and a first stopper, all mounted on the skateboard. The first upright and the second upright are located on the left and right sides of the skateboard, the second floating support is mounted on the top surface of the skateboard, and there are two sets of first stoppers distributed in front and behind.

[0010] In the pump body dual-station processing device, a locking component is installed on the slide plate. The locking component includes a Z-shaped seat installed on the side of the slide plate and a locking body installed on the Z-shaped seat.

[0011] In the pump body dual-station machining device, the second fixture includes a hydraulic expansion sleeve, four sets of side pressure cylinders distributed on the side of the hydraulic expansion sleeve, and an angular positioning component located on the adjacent side of the hydraulic expansion sleeve.

[0012] In the pump body dual-station processing device, the angular positioning component includes an adjusting cylinder and a side mounting body. The inner side of the side mounting body is provided with a first slot and a second slot. A driving block is slidably fitted in the first slot, and two sets of driving rods are slidably fitted in the second slot. The reciprocating motion of the driving block drives the driving rods to extend and retract. The end of the wedge rod away from the driving block extends to the outside of the side mounting body and is hinged to a pressure gripper. One end of the pressure gripper is a pressing end, and the other end is hinged to a fixing component. The fixing component is independently arranged.

[0013] In the pump body dual-station processing device, the drive block is provided with a wedge-shaped dovetail groove, and one end of the wedge rod is provided with a wedge-shaped dovetail block. The wedge-shaped dovetail groove and the wedge-shaped dovetail block are slidably fitted together.

[0014] In the pump body dual-station processing device, the processing device also includes a frame, which includes a base plate, side upright plate one, side upright plate two, side upright plate three, and a top plate. The pallet assembly is installed on the base plate, side upright plate one and side upright plate two are installed on the base plate from the left and right, side upright plate three is installed on the rear side of the base plate, and the top plate is fixed to the top of side upright plate one, side upright plate two, and side upright plate three for installing clamp one. Clamp two is installed on side upright plate one and side upright plate three.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model employs two sets of clamps distributed vertically and horizontally to clamp the pump body casting, thus achieving vertical distribution of the pump body casting. The top pump body casting is used for circumferential surface and hole machining, while the bottom pump body casting has end face hole machining. This vertical distribution saves structural space. A tray assembly is used to move the pump body casting into the lower clamping station. During pump body casting machining, the corresponding specification cutting tools can be used for machining the holes on the circumferential surface of the top pump body casting and the end face of the bottom pump body casting, effectively reducing tool change time and improving production efficiency.

[0017] 2. Since the pump body casting is installed on the side, the pallet assembly is used to push it to the installation position. In order to prevent the inertial force generated by pulling out the workpiece, a second stop is added to prevent the pallet assembly and the pump body casting from separating and falling off. The second stop is made of nylon material to avoid collision between the pallet assembly and the pump body casting.

[0018] 3. This utility model adopts a hydraulic expansion sleeve center positioning method, which allows for better clamping of the pump body casting. To prevent interference between the pump body casting's shape and the support when the expansion sleeve is clamped, a floating support is used, which prevents positioning misalignment due to the irregular shape of the pump body casting during clamping.

[0019] 4. This utility model provides an angular positioning component on the side of the pump body casting, which can guide the angular direction even if the position and size of the pump body casting are not uniform. Attached Figure Description

[0031] Example 1

[0032] like Figures 1 to 4 As shown, the upper and lower dual-station pump body casting processing device includes a first fixture 10, a tray assembly 20 and a second fixture 30. The first fixture 10 and the second fixture 30 are distributed vertically. The first fixture 10 vertically constrains the pump body casting, and the second fixture 30 horizontally constrains the pump body casting. A holding structure is provided on the tray assembly 20, and the second fixture 30 is distributed at the tail of the tray assembly 20.

[0033] The fixture 10 includes a positioning block 11, a floating support 12, and a clamping cylinder 13. The positioning block 11 is vertically installed on one side of the pump body casting for side positioning, the floating support 12 supports the pump body casting from the bottom, and the clamping cylinder 13 clamps and fixes the bottom mounting lugs of the pump body casting.

[0034] Among them, such as Figure 5As shown, the tray assembly 20 includes a slide rail 21 and a stop block 22 located at the end of the slide rail 21. The slide rail 21 and the stop block 22 are fixed on the base plate 41. A slider is slidably fitted on the slide rail 21, and a slide plate 23 is installed on the top of the slider.

[0035] The container structure includes a first upright 24, a second upright 25, a second floating support 26, and a first stop 27, all mounted on the slide plate 23. The first upright 24 and the second upright 25 are distributed on the left and right sides of the slide plate 23. The second floating support 26 is installed on the top surface of the slide plate 23. There are two sets of first stop 27 distributed in the front and back.

[0036] Among them, such as Figure 6 and Figure 7 As shown, the second clamp 30 includes a hydraulic expansion sleeve 31, four sets of side pressure cylinders 32 distributed on the side of the hydraulic expansion sleeve 31, and an angular positioning member 33 located on the adjacent side of the hydraulic expansion sleeve 31.

[0037] Among them, such as Figures 1 to 4 As shown, the processing device also includes a frame 40, which includes a base plate 41, a first side plate 42, a second side plate 43, a third side plate 44, and a top plate 45. The pallet assembly 20 is installed on the base plate 41. The first side plate 42 and the second side plate 43 are installed on the left and right sides of the base plate 41. The third side plate 44 is installed on the rear side of the base plate 41. The top plate 45 is fixed to the top of the first side plate 42, the second side plate 43, and the third side plate 44 for mounting a first clamp 10. The second clamp 30 is installed on the first side plate 42 and the third side plate 44.

[0038] The pump body casting is hoisted in the area between the first upright 24 and the second upright 25. The bottom is supported by the second floating support 26 and the front is constrained by the first stop block 27. Then, the slide plate 23 is moved to the rear until it is attached to the abutment on the third side plate 44. The angular positioning is completed by the angular positioning component 33. The pump body casting is clamped and fixed by the hydraulic expansion sleeve 31 and the side pressure cylinder 32. The pump body casting at the top is pressed and fixed by the clamping cylinder 13.

[0039] During machining, after the upper and lower pump bodies are clamped, the planes and holes around the upper pump body casting are machined (including drilling, milling, and milling steps), and the holes on the end face of the bottom pump body casting are machined. During the machining of the bottom and top pump body castings, the same type of tool is used for the holes or planes, and the tool does not need to be changed, thus completing the machining operation of the pump body casting.

[0040] Example 2

[0041] In the first embodiment, as Figure 4As shown, a locking member 28 is installed on the slide plate 23. The locking member 28 includes a Z-shaped seat installed on the side of the slide plate 23 and a locking body (pin) installed on the Z-shaped seat. The base plate 41 is provided with corresponding insertion holes (two sets are provided, located at the initial position and the end position respectively). The locking member 28 is used to ensure that the tray assembly 32 will not be displaced during processing.

[0042] Example 3

[0043] In the first embodiment, as Figures 8 to 10 As shown, the angular positioning component 33 includes an adjusting cylinder 331 and a side mounting body 332. The inner side of the side mounting body 332 is provided with a first slot 333 and a second slot 334. A driving block 335 is slidably fitted in the first slot 333, and two sets of driving rods 336 are slidably fitted in the second slot 334. The reciprocating motion of the driving block 335 drives the driving rods 336 to extend and retract. The end of the wedge rod away from the driving block 335 extends to the outside of the side mounting body 332 and is hinged to a clamp 337. One end of the clamp 337 is a clamping end, and the other end is hinged to a fixing component 338. The fixing component 338 is independently arranged (installed on the side support 42).

[0044] The drive block 335 is provided with a wedge-shaped dovetail groove 339, and a wedge-shaped dovetail block 3310 is provided at one end of the wedge-shaped rod. The wedge-shaped dovetail groove 339 and the wedge-shaped dovetail block 3310 are slidably fitted together.

[0045] By adjusting the output end of the hydraulic cylinder 331 and connecting it to the drive block 335, the drive block 335 is driven to reciprocate left and right. During operation, the drive rod 336 extends and retracts, thereby moving the pressure grippers 337 closer or further apart, thus enabling angular positioning of the pump body casting. Even if the pump body casting is not uniform in size or position, angular alignment can be achieved. Angular alignment ensures the machining accuracy of the top hole.

[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
