Description

Technical Field

[0001] The 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 box is one of the core components of the fracturing pump, which is mainly used to control the flow and pressure of the fluid. As the core component of the hydraulic end of the fracturing pump, the valve box is subjected to great working pressure. The processing of the fracturing pump valve box usually includes rough milling, ultrasonic flaw detection, rough machining, heat treatment, shot blasting, penetrant flaw detection and finishing, etc. When milling the existing fracturing pump valve box, the valve box needs to be placed in the machine tool fixture and fixed, and the machine tool cuts the outer surface of the valve box.

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

[0004] In view of the above-mentioned related technologies, when the fracturing pump valve box is re-faced, it is usually necessary to remove the fixture on the surface of the valve box, then turn the valve box over and re-position and clamp the valve box, and then perform the tool setting operation again during processing. The repeated clamping action 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 Since the lower side of the valve box is tilted downward, it is difficult for the milling cutter of the machine tool to contact the lower side of the valve box. After processing other sides, the operator is often required to pry up the valve box to make the lower side in a vertical state before processing again, which leads to a negative impact on the processing efficiency of the valve box.

[0023] 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 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0024] 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.

[0025] 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 through the 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 with a plurality of positioning mechanisms 4, and the positioning mechanism 4 is used to position the valve box 8 along the length and width directions.

[0026] 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 lower 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 pipe 26. The connecting pipe 26 is rotatably connected to the support plate 2. The side surface of the connecting pipe 26 is fixedly connected with a driving nut 27. The operator uses a wrench to rotate the driving nut 27. The driving nut 27 drives the first screw rod 24 to rotate through the connecting pipe 26, so that the first screw rod 24 can drive the support block 23 to slide in the front-to-back direction.

[0027] Reference Figure 3 , Figure 4 and Figure 5 The step screw 25 is threadedly connected to the support block 23. The screw rod of the step screw 25 is composed of a threaded rod and a smooth rod. The step screw 25 is threadedly connected to the support block 23 through the threaded rod. The connecting frame 5 is hinged to the support frame 3 through 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 through 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 smooth rod part of the step screw 25 through the hinge hole 511. The upper surface of the connecting frame 5 is fixedly connected with a fastening frame 52 for fastening the valve box 8.

[0028] First, the valve box 8 is placed 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 the first mechanisms 44, and the positioning mechanisms 4 located on the front and rear sides of the support frame 3 are the second mechanisms 45. The first mechanisms 44 are used to position and clamp the horizontal position of the valve box 8. The second mechanism 45 does not contact the valve box 8. The fastening frame 52 is rotated to be parallel to the left and right directions, and the pressing rod 527 is adjusted to press and fix the valve box 8 downward. The machine tool body 1 cuts the first side surface 82 and the second side surface 83. At this time, the second mechanism 45 and the fastening frame 52 will not interfere with the processing of the first side surface 82 and the second side surface 83.

[0029] Then the pressing rod 527 loosens the valve box 8, the first mechanism 44 is operated to detach from the valve box 8, the second mechanism 45 positions and clamps the valve box 8, and the connecting frame 5 is rotated around the rotating pin 54 to a position parallel to the front-back direction. At this time, the machine tool body 1 can cut the third side surface 84, and the first mechanism 44 and the fastening frame 52 will not interfere with the processing of the third side surface 84. The connecting rod 51 rotates synchronously with the connecting frame 5, and the operator twists the step screw 25 so that the polished rod part of the step screw 25 enters the hinge hole 511 and is plugged with the connecting rod 51. At this time, the connecting rod 51 can rotate around the step screw 25.

[0030] Reference Figure 3 and Figure 6 The operator rotates the first screw rod 24 by driving the nut 27 and the connecting rod 51, so that the first screw rod 24 drives the support block 23 to move forward and disengage 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 with the limit block 21, the rotating rod 22 is fixedly connected with the support frame 3, so that 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 against 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.

[0031] Thus, the fastening frame 52 cooperates with the first mechanism 44 and the second mechanism 45 respectively, so that the first side surface 82, the second side surface 83 and the third side surface 84 can be cut without disassembling the valve box 8. When the fastening frame 52 adjusts its position according to the change of the processed position of the valve box 8, the fastening frame 52 cooperates with the step screw 25, so that the support frame 3 drives the valve box 8 to rotate, and the function of rotating the lower side surface 81 of the valve box 8 to an upright state is realized without disassembling the valve box 8, so that the machine tool body 1 can realize the function of processing the lower side surface 81, which saves the operating steps of the operator and improves the processing accuracy of the valve box 8.

[0032] Reference Figure 7 The upper surface of the support block 23 is rotatably connected with 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.

[0033] 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 at 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.

[0034] The first support shell 521, the first rotating shaft 523 and the first threaded rod 525 form a screw slider structure. The operator rotates the first rotating shaft 523 to drive the first threaded rod 525 to move in the vertical direction, thereby adjusting the position of the fastening block 528 in the vertical direction. The second support shell 522, the second rotating shaft 524 and the second threaded rod 526 form a screw slider structure. The operator rotates the second rotating shaft 524 to drive the second threaded rod 526 to move in the vertical direction, thereby adjusting the position of the pressing rod 527 in the vertical direction. The pressing rod 527 moves upward to disengage from the valve box 8, and the pressing rod 527 moves downward to abut against the upper surface of the valve box 8, and 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.

[0035] Reference Figure 8The outer side surface of the abutment plate 34 is horizontally provided with a receiving groove 342, and the positioning mechanism 4 can rotate to enter the receiving 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 receiving 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, and the positioning rod 43 is fixedly sleeved on the outer side surface of the connecting bolt 42, and the positioning rod 43 can abut against the outer side surface of the valve box 8.

[0036] 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.

[0037] When the positioning mechanism 4 is loosened from the valve box 8, the operator reverses the connecting bolt 42 to make the positioning rod 43 separate from the outer side of the valve box 8, and rotates the positioning rod 43 around the connecting bolt 42 to make the positioning rod 43 parallel to the receiving groove 342. Then, the rotating tube 41 is rotated to make the rotating tube 41, the connecting bolt 42 and the positioning rod 43 enter the receiving groove 342, thereby preventing the positioning mechanism 4 from interfering with the tool during the cutting process.

[0038] Reference Figure 5 and Figure 8 The support frame 3 includes a support rail 31, a sliding block 32, a telescopic rod 33 and a material resistance plate 34. The support rail 31 is hinged to the support plate 2 through the rotating rod 22. The sliding block 32 is slidably set on the support 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.

[0039] Reference Figure 5 , two sliding blocks 32, telescopic rods 33 and abutment plates 34 are provided and located on both sides of the support plate 2, a bidirectional screw rod 35 is threadedly connected between the two abutment plates 34, and a rotation source 36 for driving the bidirectional screw rod 35 to rotate is fixedly connected to the upper surface of the support plate 2. The rotation source 36 is started to drive the two abutment plates 34 to move in the left and right directions by rotating the bidirectional screw rod 35, so as to adjust the distance between the two abutment plates 34 according to the size of the valve box 8.

[0040] Reference Figure 6 A reinforcement member 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 a tilted state. The reinforcement member 53 can abut against the outer side surface of the valve box 8, thereby supporting the tilted valve box 8 and improving the stability of the lower side surface 81 of the valve box 8 during processing.

[0041] Reference Figure 8 A buffer 6 is fixedly connected between the sliding block 32 and the material-repelling plate 34. Specifically, the buffer 6 is a lifting buffer. The buffer 6 is used to buffer the gravity of the valve box 8, so as to reduce the damage caused by the impact of the valve box 8 on the support frame 3 when the valve box 8 is transported to the support frame 3. A limiting groove 341 is provided on the lower bottom surface of the material-repelling plate 34. A first connecting rod 7 is hinged on the lower bottom surface of the material-repelling plate 34. The first connecting rod 7 is hinged on the second connecting rod 71. The valve box 8 pushes the material-repelling plate 34 downward by its own gravity. When the material-repelling 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 material-repelling plate 34 is locked, and the positioning mechanism 4 and the fastening frame 52 fix the valve box 8 to the material-repelling plate 34.

[0042] The implementation principle of a valve box parts processing equipment 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 horizontal position of the valve box 8, the fastening frame 52 is rotated to be parallel to the left and right directions, and the pressing rod 527 is adjusted to press and fix the valve box 8 downward. The machine tool body 1 cuts the first side surface 82 and the second side surface 83.

[0043] Then the pressing rod 527 loosens the valve box 8, the first mechanism 44 is separated from the valve box 8, the second mechanism 45 positions and clamps the valve box 8, the connecting frame 5 is rotated around the rotating 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, and the operator twists the step screw 25 so that the polished rod part of the step screw 25 enters the hinge hole 511 and is plugged with the connecting rod 51. 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. When 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. Therefore, 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.

[0044] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The above are preferred embodiments of the present invention.
