Description

Technical Field

[0001] The present invention relates to the technical field of parts processing, and in particular to a valve box parts processing device. Background Art

[0002] The fracturing pump valve manifold is a core component of the pump, primarily used to control fluid flow and pressure. As a core component of the hydraulic end of the fracturing pump, the valve manifold withstands extreme operating pressures. Processing of the fracturing pump valve manifold typically includes rough milling, ultrasonic testing, rough machining, heat treatment, shot blasting, penetrant testing, and finishing. Existing milling of the fracturing pump valve manifold requires the manifold to be secured in a machine tool fixture, which then cuts the outer surface of the manifold.

[0003] For example, the Chinese patent with authorization announcement number CN103862305B, named Milling Machine Clamp, when a material of a specific specification is clamped, the sliding block can be fixed to the clamping position of the material on the guide rail through the setting of a hydraulic self-locking device. When the milling machine processes the material, the sliding block will not move away from the fixed pressure block due to the thrust generated by the milling cutter, thereby ensuring the processing accuracy of the material.

[0004] Regarding the above-mentioned related technologies, when resurfacing the fracturing pump valve box, it is usually necessary to remove the fixture on the valve box surface, then flip the valve box and reposition and clamp the valve box, and then perform the tool setting operation again during processing. Repeated clamping actions will reduce the overall processing efficiency of the valve box and may also affect the final processing accuracy of the valve box. In addition, referring to Figure 1 Because the lower side of the valve box is tilted downward, the milling cutter of the machine tool is difficult to contact the lower side of the valve box. After processing other sides, the operator often needs to pry up the valve box to make the lower side in a vertical state before processing again, which in turn has a negative impact on the processing efficiency of the valve box. Summary of the Invention

[0005] In view of this, the present invention provides a valve box parts processing equipment, which aims to solve the problems that the valve box needs to be positioned and clamped multiple times during the processing, and the lower side of the valve box is difficult to be processed.

[0006] The cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame to support the valve box.

[0007] By adopting the above technical solution, the fastening frame cooperates with the first mechanism and the second mechanism respectively, enabling the outer side of the valve box to be cut without disassembling the valve box. When the fastening frame adjusts its position according to the changes in the position of the valve box to be processed, the fastening frame cooperates with the stepped screw, thereby enabling the support frame to drive the valve box to rotate, realizing the function of rotating the lower side of the valve box to an upright position without disassembling the valve box, thereby enabling the machine tool body to complete the function of processing the lower side. This saves the operator's operating steps, improves the processing accuracy of the valve box, and reduces the processing cost of the valve box.

[0009] By adopting the above technical solution, the pressing rod moves downward to abut against the upper surface of the valve box, and then the fastening block moves downward to squeeze the pressing rod, increasing the fastening force of the pressing rod on the valve box, thereby fixing the valve box on the support frame.

[0010] Optionally, the positioning mechanism includes a rotating tube, a connecting bolt and a positioning rod, the rotating tube is hinged to the support frame, the connecting bolt is threadedly connected to the rotating tube, the positioning rod is fixedly sleeved on the outer side of the connecting bolt, and the positioning rod can abut against the outer side of the valve box.

[0011] Optionally, the support frame includes a support rail, a sliding block, a telescopic rod and a material resistance plate. The support rail is hinged to the support plate through the rotating rod. The sliding block is slidably set on the support rail. The material resistance plate is located above the sliding block. The telescopic rod is fixedly connected between the sliding block and the material resistance plate.

[0012] Optionally, two of the sliding block, the telescopic rod and the support block are provided and located on both sides of the support plate, a bidirectional screw is threadedly connected between the two support blocks, and a rotation source for driving the bidirectional screw to rotate is fixedly connected to the upper surface of the support plate.

[0013] Optionally, the upper surface of the support block is rotatably connected to a support ball, and the support ball abuts against the lower bottom surface of the support frame.

[0014] By adopting the above technical solution, when the support block moves away from the support frame, the support balls reduce the friction between the support block and the support frame.

[0015] Optionally, a reinforcement piece is fixedly connected to a side surface of the fastening frame, and when the fastening frame rotates around the rotating rod, the reinforcement piece can abut against an outer side surface of the valve box.

[0016] By adopting the above technical solution, when the fastening frame rotates around the rotating rod, the valve box is in an inclined state, and the reinforcement can abut against the outer side surface of the valve box, thereby supporting the inclined valve box and improving the stability of the lower side of the valve box when being processed.

[0017] Optionally, a buffer is fixedly connected between the sliding block and the material resistance plate, and the buffer is used to buffer the gravity of the valve box.

[0018] By adopting the above technical solution, the buffer is used to buffer the gravity of the valve box, thereby reducing the damage caused by the impact of the valve box on the support frame when it is transported to the support frame.

This saves the operator steps, improves the processing accuracy of the valve box, and reduces the processing cost of the valve box. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 2-Figure 8 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments derived by ordinary technicians in this field fall within the scope of protection of the present invention.

[0031] This embodiment provides a valve box parts processing equipment, referring to Figure 2 、 Figure 3 and Figure 4 A valve box parts processing equipment includes a machine tool body 1, a support plate 2, a limit block 21, a rotating rod 22, a support frame 3, a positioning mechanism 4, a support block 23, a first screw rod 24, a step screw 25, a connecting frame 5, a connecting rod 51 and a fastening frame 52.

[0032] Reference Figure 2 、 Figure 3 and Figure 4The machine tool body 1 is erected on a horizontal plane and is used to process the valve box 8. The front side of the valve box 8 is the first side 82, the rear side of the valve box 8 is the second side 83, and the left and right sides of the valve box 8 are the third side 84. The machine tool body 1 is a gantry machining center, which can cut the side walls of the valve box 8 in the left and right and front and back directions. The support plate 2 is fixedly connected to the upper surface of the machine tool body 1, and the limit block 21 is fixedly connected to the upper surface of the support plate 2. The support frame 3 is hinged to the upper end of the limit block 21 by a rotating rod 22, and the valve box 8 to be processed is placed on the upper surface of the support frame 3. The positioning mechanism 4 is hinged to the side wall of the support frame 3 and is provided in plurality. The positioning mechanism 4 is used to position the valve box 8 along the length and width directions.

[0033] Reference Figure 3 and Figure 4 The support block 23 is slidably connected to the upper surface of the support plate 2. The support block 23 can slide in the front-to-back direction. When the support block 23 slides to the bottom of the support frame 3, it can support the support frame 3. The support ball 231 abuts against the bottom surface of the support frame 3. The first screw rod 24 is threadedly connected to the support block 23. The outer side surface of the first screw rod 24 is fixedly sleeved with a connecting tube 26. The connecting tube 26 is rotatably connected to the support plate 2. The side surface of the connecting tube 26 is fixedly connected to a drive nut 27. The operator uses a wrench to rotate the drive nut 27. The drive nut 27 drives the first screw rod 24 to rotate through the connecting tube 26, so that the first screw rod 24 can drive the support block 23 to slide in the front-to-back direction.

[0034] Reference Figure 3 、 Figure 4 and Figure 5 The step screw 25 is threadedly connected to the support block 23. The screw rod portion of the step screw 25 consists of a threaded rod and a polished rod. The step screw 25 is threadedly connected to the support block 23 via the threaded rod. The connecting frame 5 is hinged to the support frame 3 via a rotating pin 54. The connecting frame 5 is provided with a waist-shaped groove. The connecting rod 51 is hinged to the connecting frame 5 via the waist-shaped groove. The connecting rod 51 is provided with a hinge hole 511. The rotation of the connecting frame 5 can drive the connecting rod 51 to rotate, so that the connecting rod 51 is hinged to the polished rod portion of the step screw 25 through the hinge hole 511. The upper surface of the connecting frame 5 is fixedly connected to a fastening frame 52 for fastening the valve box 8.

[0035] First, place the valve box 8 on the upper surface of the support frame 3. The positioning mechanisms 4 located on the left and right sides of the support frame 3 are first mechanisms 44, and the positioning mechanisms 4 located on the front and rear sides of the support frame 3 are second mechanisms 45. The first mechanisms 44 are used to position and clamp the valve box 8 horizontally. The second mechanisms 45 do not contact the valve box 8. The fastening frame 52 is rotated parallel to the left and right directions, and the press rod 527 is adjusted to press the valve box 8 downward and secure it. The machine tool body 1 cuts the first side surface 82 and the second side surface 83. At this time, the second mechanisms 45 and the fastening frame 52 do not interfere with the processing of the first side surface 82 and the second side surface 83.

[0036] The press rod 527 then releases the valve box 8, manipulating the first mechanism 44 to detach from the valve box 8. The second mechanism 45 then positions and clamps the valve box 8, and the connecting frame 5 is rotated about the rotating pin 54 to a position parallel to the front-to-back direction. The machine tool body 1 is now able to cut the third side surface 84, and the first mechanism 44 and the fastening frame 52 do not interfere with the processing of the third side surface 84. The connecting rod 51 rotates synchronously with the connecting frame 5. The operator twists the step screw 25, causing the polished portion of the step screw 25 to enter the hinge hole 511 and engage with the connecting rod 51. The connecting rod 51 is now able to rotate about the step screw 25.

[0037] Reference Figure 3 and Figure 6 The operator rotates the first screw rod 24 by driving the nut 27 and the connecting rod 51, thereby causing the first screw rod 24 to drive the support block 23 to move forward and separate from the support frame 3. While the support block 23 moves, it drives the connecting rod 51 to rotate clockwise around the step screw 25 (refer to Figure 6 ), since the support block 23 is separated from the support frame 3, and the rotating rod 22 is rotatably connected to the limit block 21, the rotating rod 22 is fixedly connected to the support frame 3, thereby the connecting rod 51 drives the rotating rod 22 to rotate counterclockwise through the connecting frame 5, and the support frame 3 rotates synchronously with the rotating rod 22, and the support frame 3 drives the valve box 8 to rotate counterclockwise (refer to Figure 6 ), until the support frame 3 abuts the limit surface, at which time the lower side surface 81 is rotated to a vertical state. The second mechanism 45 loosens the valve box 8, and the first mechanism 44 tightens the valve box 8, so that the machine tool body 1 can cut the lower side surface 81.

[0038] As a result, the fastening frame 52 cooperates with the first mechanism 44 and the second mechanism 45 respectively, and the first side surface 82, the second side surface 83, and the third side surface 84 are cut without disassembling the valve box 8. When the fastening frame 52 is adjusted according to the change in the position of the valve box 8 to be processed, the fastening frame 52 cooperates with the stepped screw 25, thereby enabling the support frame 3 to drive the valve box 8 to rotate, and realizing the function of rotating the lower side surface 81 of the valve box 8 to an upright state without disassembling the valve box 8, thereby enabling the machine tool body 1 to process the lower side surface 81, saving the operator's operating steps and improving the processing accuracy of the valve box 8.

[0039] Reference Figure 7 The upper surface of the support block 23 is rotatably connected to a support ball 231. When the first screw rod 24 drives the support block 23 to move away from the support frame 3, the support ball 231 reduces the friction between the support block 23 and the support frame 3.

[0040] Reference Figure 5 and Figure 7 The fastening frame 52 includes a first supporting shell 521, a second supporting shell 522, a first rotating shaft 523, a second rotating shaft 524, a first threaded rod 525, a second threaded rod 526, a press rod 527 and a fastening block 528. The first supporting shell 521 and the second supporting shell 522 are both fixedly connected to the connecting frame 5, the first rotating shaft 523 is rotatably connected to the first supporting shell 521, the second rotating shaft 524 is rotatably connected to the second supporting shell 522, the first threaded rod 525 is threadedly connected to the first rotating shaft 523, the second threaded rod 526 is threadedly connected to the second rotating shaft 524, the press rod 527 is hinged to the upper end of the first threaded rod 525, the fastening block 528 is fixedly connected to the upper surface of the second threaded rod 526, the press rod 527 can abut against the upper surface of the valve box 8, and the fastening block 528 is used to press the press rod 527 downward.

[0041] The first support shell 521, the first rotating shaft 523 and the first threaded rod 525 form a screw slider structure. When the operator rotates the first rotating shaft 523, the first threaded rod 525 can be driven to move in the vertical direction, thereby adjusting the vertical position of the fastening block 528. The second support shell 522, the second rotating shaft 524 and the second threaded rod 526 form a screw slider structure. When the operator rotates the second rotating shaft 524, the second threaded rod 526 can be driven to move in the vertical direction, thereby adjusting the vertical position of the pressing rod 527. The pressing rod 527 moves upward to disengage from the valve box 8, and moves downward to abut against the upper surface of the valve box 8. Then, the fastening block 528 moves downward to squeeze the pressing rod 527, increasing the fastening force of the pressing rod 527 on the valve box 8, thereby fixing the valve box 8 on the support frame 3.

[0042] Reference Figure 8The outer side surface of the resisting plate 34 is horizontally provided with an accommodating groove 342, and the positioning mechanism 4 can rotate to enter the accommodating groove 342. The positioning mechanism 4 includes a rotating tube 41, a connecting bolt 42 and a positioning rod 43. The rotating tube 41 is hinged to the inner top surface of the accommodating groove 342. The rotating tube 41 is not higher than the upper surface of the support frame 3. The connecting bolt 42 is threadedly connected to the rotating tube 41. The positioning rod 43 is fixedly sleeved on the outer side surface of the connecting bolt 42 and can abut against the outer side surface of the valve box 8.

[0043] When the positioning mechanism 4 clamps and positions the valve box 8, the operator rotates the rotating tube 41 to the outside of the accommodating groove 342, and rotates the positioning rod 43 to an upright state, rotates the connecting bolt 42 to adjust the distance of the positioning rod 43 relative to the valve box 8, so that the positioning rod 43 abuts against the outer side surface of the valve box 8, and tightens the connecting bolt 42 so that the positioning rods 43 on both sides of the valve box 8 clamp and position the valve box 8.

[0044] When the positioning mechanism 4 is released from the valve housing 8, the operator reverses the connecting bolt 42 to separate the positioning rod 43 from the outer side of the valve housing 8, and rotates the positioning rod 43 around the connecting bolt 42 until the positioning rod 43 is parallel to the receiving groove 342. The operator then rotates the rotating tube 41 so that the rotating tube 41, connecting bolt 42, and positioning rod 43 enter the receiving groove 342, thereby preventing the positioning mechanism 4 from interfering with the tool during the cutting process.

[0045] Reference Figure 5 and Figure 8 The support frame 3 includes a support guide rail 31, a sliding block 32, a telescopic rod 33 and a material resistance plate 34. The support guide rail 31 is hinged to the support plate 2 through the rotating rod 22. The sliding block 32 is slidably set on the support guide rail 31. The sliding block 32 can slide in the left and right directions. The material resistance plate 34 is located above the sliding block 32. The valve box 8 is placed on the upper surface of the material resistance plate 34. The telescopic rod 33 is fixedly connected between the sliding block 32 and the material resistance plate 34.

[0046] Reference Figure 5 Two sliding blocks 32, telescopic rods 33, and abutment plates 34 are each provided and located on either side of the support plate 2. A bidirectional screw rod 35 is threadedly connected between the two abutment plates 34. A rotation source 36 is fixedly connected to the upper surface of the support plate 2 for driving the bidirectional screw rod 35 to rotate. When the rotation source 36 is activated, the bidirectional screw rod 35 rotates, driving the two abutment plates 34 to move left and right, thereby adjusting the distance between the two abutment plates 34 according to the size of the valve box 8.

[0047] Reference Figure 6 A reinforcement 53 is fixedly connected to the side of the fastening frame 52. When the fastening frame 52 rotates around the rotating rod 22, the valve box 8 is in an inclined state, and the reinforcement 53 can abut against the outer side surface of the valve box 8, thereby supporting the inclined valve box 8 and improving the stability of the lower side surface 81 of the valve box 8 during processing.

[0048] Reference Figure 8 A buffer 6 is fixedly connected between the sliding block 32 and the resisting plate 34. Specifically, the buffer 6 is a lifting buffer. The buffer 6 is used to buffer the gravity of the valve box 8, thereby reducing the damage caused by the impact of the valve box 8 on the support frame 3 when it is transported to the support frame 3. A limiting groove 341 is provided on the lower bottom surface of the resisting plate 34. A first connecting rod 7 is hinged on the lower bottom surface of the resisting plate 34. The first connecting rod 7 is hinged on the second connecting rod 71. The valve box 8 pushes the resisting plate 34 downward by its own gravity. When the resisting plate 34 moves, it pushes the first connecting rod 7 and the second connecting rod 71 to rotate until the second connecting rod 71 abuts against the inner side of the limiting groove 341. At this time, the downward movement of the valve box 8 and the resisting plate 34 is locked, and the positioning mechanism 4 and the fastening frame 52 fix the valve box 8 to the resisting plate 34.

[0049] The working principle of a valve box parts processing apparatus according to an embodiment of the present invention is as follows: First, the valve box 8 is placed on the upper surface of the support frame 3. The first mechanism 44 positions and clamps the valve box 8 horizontally. The fastening frame 52 is rotated parallel to the left and right directions. The press rod 527 is adjusted to press the valve box 8 downward and secure it. The machine tool body 1 then cuts the first side surface 82 and the second side surface 83.

[0050] The press rod 527 then releases the valve housing 8, disengaging the first mechanism 44 from the valve housing 8. The second mechanism 45 then positions and clamps the valve housing 8. The connecting frame 5 is then rotated about the rotation pin 54, and the machine tool body 1 cuts the third side surface 84. The connecting rod 51 rotates synchronously with the connecting frame 5. The operator torques the stepped screw 25, causing the polished portion of the stepped screw 25 to enter the hinge hole 511, thereby engaging the connecting rod 51. The operator then rotates the first screw 24 by driving the nut 27 and the connecting rod 51, causing it to move forward and disengage the support block 23 from the support frame 3. While the support block 23 moves, the connecting rod 51 is driven to rotate through the step screw 25, and the rotating rod 22 is fixedly connected to the support frame 3. As a result, the connecting rod 51 drives the rotating rod 22 to rotate through the connecting frame 5, and the support frame 3 rotates synchronously with the rotating rod 22. The support frame 3 drives the valve box 8 to rotate until the support frame 3 abuts against the limit surface. At this time, the lower side surface 81 is rotated to a vertical state, the second mechanism 45 loosens the valve box 8, and the first mechanism 44 tightens the valve box 8, so that the machine tool body 1 can cut the lower side surface 81.

[0051] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0052] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
