Description

Technical Field

[0001] This utility model relates to the technical field of jigs for drilling plunger pumps, specifically a jig for drilling the motor housing of a plunger pump. Background Technology

[0002] In the field of mechanical manufacturing and processing, piston pumps are an important power component and are widely used in various hydraulic systems. As one of the core components of piston pumps, the machining accuracy of the piston pump motor housing directly affects the overall performance and reliability of the piston pump. Among them, the drilling process is a key link in the machining process of piston pump motor housing. The accuracy and quality of drilling play a decisive role in subsequent assembly and normal operation of piston pumps.

[0003] The piston pump motor housing has an irregular shape and specific structural features. When drilling holes in the end face of the piston pump housing, there is often no specific fixture to stably fix the housing. This causes the housing to shift or vibrate during the drilling process, which seriously affects the drilling accuracy and causes quality problems such as hole position deviation and inaccurate hole diameter, reducing the product qualification rate. Furthermore, the existing fixtures cannot fix the piston pump housing according to different bending angles, and have poor adaptability. Utility Model Content

[0004] The technical problem to be solved by this utility model is that when drilling holes in the end face of the existing plunger pump housing, there is often no suitable clamp for stable fixation, resulting in displacement vibration and poor accuracy. Furthermore, the existing clamps are difficult to fix according to the bending angle of the housing, and have poor adaptability.

[0005] To solve the above problems, the technical solution adopted by this utility model is a clamp for drilling holes in the housing of a plunger pump motor, including a base, a clamping structure above the base, and an angle adjustment mechanism between the clamping structure and the base.

[0006] The clamping structure includes an adjusting plate hinged to the upper side of the base, a pair of sliding clamps above the adjusting plate, an upper clamp above the sliding clamps, an adjusting bolt rotatably mounted on the upper side of the sliding clamps, and a threaded hole that mates with the adjusting bolt on the side of the upper clamp. Rotating the adjusting bolt can drive the upper clamp to move up and down. A limit rod is fixed on the upper side of the sliding clamp at the other end of the adjusting bolt, and a limit cylinder that mates with the limit rod is fixed on the upper side of the upper clamp, which can ensure the stable sliding of the upper clamp.

[0007] The angle adjustment mechanism includes a rotating block rotatably mounted on one side of the adjustment plate, an adjusting threaded rod rotatably connected to the rotating block, a connecting block rotatably mounted on the upper side of the base, and the bottom end of the adjusting threaded rod rotatably mounted on the side of the connecting block. By rotating the adjusting threaded rod, the rotating block can be moved outside the adjusting threaded rod, thereby adjusting the angle of the adjustment plate.

[0008] As a further embodiment of this utility model: the lower side of the sliding clamp is provided with limit holes and threaded limit holes at both ends, and two pairs of support seats are fixed on the upper side of the adjusting plate. A limit rod that cooperates with the limit hole is fixed between one pair of support seats to ensure the stable sliding of the sliding clamp. A double threaded adjusting screw that cooperates with the threaded limit hole is rotatably provided between the other pair of support seats, which can drive the two sliding clamps to move in different directions at the same time.

[0009] As a further embodiment of this utility model: a plunger pump housing is provided between a pair of sliding clamping plates, and a flange connecting plate is fixed on the outside of the plunger pump housing. The upper clamping plate and the sliding clamping plate are respectively clamped above and below the flange connecting plate, which can stably fix the plunger pump housing to facilitate drilling.

[0010] As a further embodiment of this utility model, the included angle between the adjusting plate and the base is in the range of five to fifteen degrees, so as to adapt to plunger pump housings with different curvatures and shapes.

[0011] As a further embodiment of this utility model: the base is parallel to the top end face of the plunger pump housing, so that when drilling the end face of the plunger pump housing, the hole can be perpendicular to the end face of the plunger pump housing.

[0012] As a further embodiment of this utility model: one end of the adjusting bolt, the adjusting threaded rod, and the double-threaded adjusting screw is fixed with an anti-slip handle to facilitate rotation.

[0013] Compared with the prior art, the advantages of this utility model are as follows: This application adds a base, an adjustment plate and an angle adjustment mechanism. Through the angle adjustment mechanism, the angle of the end face to be processed of the plunger pump housing can be controlled to adapt to the drilling angle and to plunger pump housings with different curvatures. The addition of a clamping structure allows for the fixing of plunger pump housings with different diameters and flange connection plate thicknesses through the cooperation of the upper clamping plate and the sliding clamping plate. It has strong versatility. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0023] Combined with appendix Figure 1-4It can be seen that the structure includes a base 1, a clamping structure on top of the base 1, and an angle adjustment mechanism between the clamping structure and the base 1. The clamping structure includes an adjusting plate 2 hinged to the upper side of the base 1, a pair of sliding clamping plates 3 on top of the adjusting plate 2, an upper clamping plate 4 on top of the sliding clamping plates 3, an adjusting bolt 5 rotatably mounted on the upper side of the sliding clamping plates 3, and a threaded hole that mates with the adjusting bolt 5 on the side of the upper clamping plate 4. Rotating the adjusting bolt 5 can drive the upper clamping plate 4 to move up and down. A limit rod 6 is fixed on the upper side of the sliding clamping plate 3 at the other end of the adjusting bolt 5, and a limit cylinder 7 that mates with the limit rod 6 is fixed on the upper side of the upper clamping plate 4 to ensure stable sliding of the upper clamping plate 4. Limiting holes and threaded limit holes are respectively opened at both ends of the lower side of the sliding clamping plate 3, and two pairs of supports are fixed on the upper side of the adjusting plate 2. A pair of support seats 11 are fixed with a limiting rod 12 that mates with a limiting hole, which can ensure the stable sliding of the sliding clamp 3. Another pair of support seats 11 are rotatably provided with a double threaded adjusting screw 13 that mates with a threaded limiting hole, which can simultaneously drive the two sliding clamps 3 to move in different directions. A plunger pump housing 14 is provided between the pair of sliding clamps 3. A flange connecting plate 15 is fixed to the outside of the plunger pump housing 14. The upper clamp 4 and the sliding clamp 3 are respectively clamped above and below the flange connecting plate 15, which can stably fix the plunger pump housing 14. The base 1 is parallel to the top end face of the plunger pump housing 14, so that when drilling the end face of the plunger pump housing 14, the hole can be perpendicular to the end face of the plunger pump housing 14, which is convenient for drilling.

[0024] Combined with appendix Figure 2 It can be seen that the angle adjustment mechanism includes a rotating block 8 rotatably disposed on one side of the adjustment plate 2. The rotating block 8 is threadedly connected to an adjusting threaded rod 9. A connecting block 10 is rotatably disposed on the upper side of the base 1. The bottom end of the adjusting threaded rod 9 is rotatably disposed on the side of the connecting block 10. By rotating the adjusting threaded rod 9, the rotating block 8 can be moved outside the adjusting threaded rod 9, thereby adjusting the angle of the adjustment plate 2. The included angle between the adjustment plate 2 and the base 1 is 15 degrees, which can adapt to the curvature of the plunger pump housing 14. One end of the adjusting bolt 5, the adjusting threaded rod 9, and the double-threaded adjusting screw 13 are all fixed with anti-slip handles to facilitate rotation.

[0025] The working principle of this application is as follows: When drilling the end face of the plunger pump housing 14, the base 1 is first fixed to the worktable of the drilling machine with bolts. Then, the plunger pump housing 14 is placed above the adjusting plate 2. By rotating the double thread adjusting screw 13, a pair of sliding clamps 3 are moved towards the plunger pump housing 14 at the same time, and the flange connecting plate 15 is positioned above the sliding clamps 3. Then, the adjusting bolt 5 is rotated to move the upper clamp 4, so as to clamp and fix the flange connecting plate 15, thereby stabilizing the position of the plunger pump housing 14. Then, the adjusting thread rod 9 is rotated to move the rotating block 8 outside the adjusting thread rod 9, so as to adjust the angle of the adjusting plate 2, so that the end face of the plunger pump housing 14 is parallel to the base 1, so as to make the drill hole perpendicular to the end face of the plunger pump housing 14 and ensure the machining accuracy.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto.
