Description

Technical Field

[0001] This utility model relates to the field of pump and valve processing technology, specifically to an adjustable downward pressure fixture for pump and valve hardware. Background Technology

[0002] Pump valves are a general term encompassing both pumps and valves. It doesn't refer to valves used for pumps or valves that function like pumps. Pumps and valves are often linked because of their applications. That is, where there are pumps, there are generally valves, and where there are pumps, there is often a need for them. Both are used for liquid transportation. Of course, valves are also used for gases.

[0003] When machining pumps and valves, such as during drilling, the valves need to be secured. However, due to the often irregular shape of the valve's outer surface, conventional clamps cannot provide stable clamping, leading to displacement during drilling and potentially rendering the valve unusable. Therefore, there is an urgent need to design an adjustable, downward-pressing clamp for pump and valve hardware to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable downward clamp for pump and valve hardware to solve the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable pressure clamp for pump valve hardware includes a base plate, wherein a central column is fixedly installed at the top center of the base plate.

[0007] A sliding pressure plate is provided on the upper outer side of the central column, and a pressure mechanism is provided inside the top of the central column. The pressure mechanism is at least used for the sliding of the pressure plate on the central column.

[0008] A positioning platform is sleeved on the lower outer side of the central column, and a connecting arm assembly is provided on the positioning platform. The top end of the connecting arm assembly is rotatably connected to the lower pressure plate.

[0009] A pump valve is fitted onto the outside of the positioning platform and connecting arm assembly.

[0010] The connecting arm assembly is used at least to clamp and fix the inside of the pump valve.

[0011] Preferably, the base plate has several mounting holes at its edge, and a shallow groove is provided on the outer wall of the top of the base plate, with an anti-slip surface inside the groove.

[0012] Preferably, the anti-slip surface is composed of several protrusions, and the lower surface of the pump valve abuts against the surface of the anti-slip surface.

[0014] Preferably, the positioning platform includes a receiving seat, which is sleeved on the outside of the central column. Positioning nut one and positioning nut two are respectively provided above and below the receiving seat. Positioning nut one and positioning nut two are threaded onto the outer surface of the central column. The outer surface of positioning nut one is provided with a plurality of tool grooves.

[0015] Preferably, the connecting arm assembly includes a hinge seat disposed on the outer wall of the bottom of the lower pressure plate, a connecting rod rotatably connected to the hinge seat, a rotating joint disposed at the bottom end of the connecting rod, a plurality of supports disposed on the outer wall of the top of the positioning platform, and a rocker arm rotatably disposed on the supports, one end of the rocker arm being connected to the rotating joint, and a contact head being fixedly disposed at the other end of the rocker arm.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown in the figure, an adjustable downward pressure clamp for pump valve hardware provided by this utility model embodiment includes a base plate 1, a central column 3 fixedly installed at the top center of the base plate 1; a downward pressure plate 4 that slides up and down is provided on the upper outside of the central column 3, and a downward pressure mechanism 7 is provided inside the top of the central column 3, the downward pressure mechanism 7 being used at least for sliding the downward pressure plate 4 on the central column 3; a positioning platform 5 is sleeved on the lower outside of the central column 3, a connecting arm assembly 6 is provided on the positioning platform 5, and the top of the connecting arm assembly 6 is rotatably connected to the downward pressure plate 4; a pump valve 2 is sleeved on the outside of the positioning platform 5 and the connecting arm assembly 6; the connecting arm assembly 6 is used at least for clamping and fixing the inside of the pump valve 2.

[0029] In this embodiment, a base plate 1 is included;

[0030] Specifically, a number of mounting holes 11 are provided at the edge of the base plate 1. Bolts can be inserted into the mounting holes 11 to connect the base plate 1 with the drilling equipment. A shallow groove is provided on the outer wall of the top of the base plate 1, and an anti-slip surface 12 is provided inside the shallow groove. The use of the anti-slip surface 12 further increases the stability of the pump valve 2 after the bottom of the pump valve 2 contacts the base plate 1.

[0031] Specifically, the anti-slip surface 12 is composed of several protrusions, and the lower surface of the pump valve 2 abuts against the surface of the anti-slip surface 12.

[0032] In this embodiment, a central column 3 is fixedly installed at the top center of the base plate 1;

[0033] Specifically, several through holes 31 are provided on the lower outer surface of the central column 3. The connecting arm assembly 6 is inserted into the through holes 31. When the connecting arm assembly 6 moves, it can enter the through holes 31 to avoid the central column 3 interfering with the movement of the connecting arm assembly 6. A limiting slot 33 is provided on the upper outer surface of the central column 3. The lower pressure block 76 is slidably inserted into the limiting slot 33 to limit and guide the lower pressure block 76. A threaded part 32 is provided on the lower outer surface of the central column 3. Positioning nut 1 52 and positioning nut 2 53 are threadedly sleeved on the threaded part 32 to fix and limit the receiving seat 51 outside the central column 3.

[0034] In this embodiment, a sliding pressure plate 4 is provided on the upper outer surface of the central column 3, and the pressure plate 4 has a circular structure.

[0035] In this embodiment, a pressing mechanism 7 is provided inside the top of the central column 3. The pressing mechanism 7 is at least used for the sliding of the pressing plate 4 on the central column 3.

[0036] Specifically, the pressing mechanism 7 includes a bearing seat 72 disposed inside the central column 3, and a lead screw 71 is rotatably disposed inside the bearing seat 72. A stabilizing block 73 fixed to the top of the central column 3 is disposed outside the lead screw 71. A handle 74 is disposed at the top of the lead screw 71. A lead screw nut 75 is threaded onto the outside of the lead screw 71, and several pressing blocks 76 are disposed on the outer wall of the lead screw nut 75. When operating the pressing mechanism 7, the handle 74 can be held by hand to drive the lead screw 71 to rotate. The rotation of the lead screw 71 drives the lead screw nut 75 to move up and down, and at the same time, the pressing blocks 76 are moved up and down inside the limiting slot 33. The number of pressing blocks 76 is preferably four.

[0037] In this embodiment, a positioning platform 5 is sleeved on the lower outer side of the central column 3;

[0038] Specifically, the positioning table 5 includes a receiving seat 51, which is sleeved on the outside of the central column 3. Positioning nut 1 52 and positioning nut 2 53 are respectively provided above and below the receiving seat 51. By adjusting the position of positioning nut 1 52 and positioning nut 2 53 on the central column 3, the position of the receiving seat 51 can be adjusted, thus making it suitable for clamping and positioning pump valves 2 of different specifications. Positioning nut 1 52 and positioning nut 2 53 are threaded onto the outer surface of the central column 3. The outer surface of positioning nut 1 52 is provided with several tool slots 54. Due to the presence of the connecting arm assembly 6, ordinary tools may not be able to operate positioning nut 1 52 properly. Tools can be inserted into the tool slots 54 and hammered to make positioning nut 1 52 rotate outside the central column 3, thus achieving pre-tightening and loosening.

[0039] In this embodiment, a connecting arm assembly 6 is provided on the positioning platform 5, and the top end of the connecting arm assembly 6 is rotatably connected to the lower pressure plate 4.

[0040] In this embodiment, the positioning platform 5 and the connecting arm assembly 6 are externally sleeved with the pump valve 2; the connecting arm assembly 6 is at least used to clamp and fix the inside of the pump valve 2.

[0041] Specifically, the connecting arm assembly 6 includes a hinge seat 61 disposed on the outer wall of the bottom of the lower pressure plate 4. A connecting rod 62 is rotatably connected to the hinge seat 61. A rotating joint 66 is disposed at the bottom end of the connecting rod 62. Several supports 63 are disposed on the outer wall of the top of the positioning platform 5. A rocker arm 64 is rotatably disposed on the support 63. One end of the rocker arm 64 is connected to the rotating joint 66. A contact head 65 is fixedly disposed at the other end of the rocker arm 64. After the lower pressure plate 4 descends, the lower pressure plate 4 will drive the connecting rod 62 to move downward. The connecting rod 62 presses against one end of the rocker arm 64, causing the rocker arm 64 to rotate on the support 63. At this time, the contact head 65 moves synchronously with the rocker arm 64, so that the contact head 65 abuts against the inner surface of the pump valve 2. As the lower pressure plate 4 continues to descend, the pump valve 2 is pre-tightened. When the pump valve 2 is released, it is only necessary to move the lower pressure mechanism 7 upward.

[0042] Working steps: 1. The operator can fix the fixture to the drilling equipment through the base plate 1;

[0043] Second, next, put the pump valve 2 on the outside of the central column 3, so that the lower surface of the pump valve 2 contacts the anti-slip surface 12.

[0044] Third, manually operate the pressing mechanism 7 so that the pressing mechanism 7 drives the pressing plate 4 to descend along the central column 3;

[0045] Fourth, the lower pressure plate 4 drives the connecting arm assembly 6 to move. At this time, the positioning table 5 and the central column 3 are relatively fixed. The rocker arm 64 of the connecting arm assembly 6 rotates and uses the contact head 65 to contact the inner wall of the pump valve 2, thereby realizing the stable clamping and fixing of the pump valve 2 by the fixture.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
