Description

Technical Field

[0001] The invention relates to the technical field of sensor processing, and in particular to processing equipment for a mining differential pressure sensor. Background Art

[0002] The mining differential pressure sensor converts the differential pressure in the mine into a standard electrical signal continuously and automatically through the sensing probe and transmits it to the matching equipment to avoid the risk of explosion caused by high concentration of gas or coal dust in the mine. The external main structure of the probe consists of a cylindrical metal shell and pressure interfaces welded at both ends.

[0003] However, the current mining differential pressure sensors have the following main problems in the processing process: 1. During the batch welding of the probe housing and pressure interface by existing processing equipment, it is necessary to disassemble and assemble the housing many times to weld the pressure interfaces at both ends of the housing and replace the probe. This method is cumbersome and has low processing efficiency.

[0004] 2. Since the radius of the prism circumscribed circle of the pressure interface is larger than the radius of the shell, after one end of the shell is welded to the pressure interface, when welding the other end of the shell, in order to ensure the docking of the pressure interface and the shell and the welding quality, it is necessary to clamp the threaded part of the pressure interface. This clamping method is easy to damage the thread teeth and affect the subsequent assembly operation.

[0005] Therefore, in order to improve the processing efficiency of the probe housing and the pressure interface and ensure the overall integrity of the probe after welding, the present invention provides a processing equipment for a mining differential pressure sensor. Summary of the invention

[0030] The embodiments of the present invention are described below with reference to the accompanying drawings. In the process, in order to ensure the clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0031] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0032] See also Figure 1 A processing equipment for a differential pressure sensor for mining includes a workbench 1, a docking drive mechanism 2, a feeding mechanism 3 and a unloading mechanism 4; a fixing frame is installed on the lower end surface of the workbench 1, a docking drive mechanism 2 is arranged on the upper end surface of the workbench 1, a feeding mechanism 3 is arranged on the right side of the docking drive mechanism 2, and a unloading mechanism 4 is arranged on the front side of the docking drive mechanism 2, and the unloading mechanism 4 and the feeding mechanism 3 are both installed on the upper end surface of the workbench 1.

[0033] See also Figure 1 , Figure 2 and Figure 3 The docking drive mechanism 2 includes a guide plate 20, a support plate 21, a slide groove 22, a clamping unit 5, a rotation unit 6 and a fixed drive unit 7. The upper end surface of the workbench 1 is symmetrically installed with a support plate 21, and a group of guide members for fixed guiding are symmetrically arranged between the two support plates 21. Each group of guide members has two guide plates 20, and the guide plates 20 are L-shaped. The two guide plates 20 in the same group are symmetrical and fixedly connected to the support plates 21. The opposite surfaces of the vertical sections of the two guide plates 20 in the same group are provided with slide grooves 22. The clamping unit 5 is slidably installed between the two guide plates 20 located at the top, and a rotation unit 6 for driving the clamping unit 5 is arranged below the clamping unit 5. The front and rear sides of the guide plates 20 are jointly installed with a fixed drive unit 7.

[0034] During the specific work, for the initial processing, a shell can be manually placed on the positioning block 50, and then the positioning block 50 is driven to move toward the processing area through the adjustment unit. During the downward movement of the positioning block 50, it will interfere with the clamping unit 5 to squeeze and fix the shell. Then, the pressure interface and the shell are connected and rotated through the fixed driving unit 7 for welding processing. After the welding of one end of the shell is completed, the turning mechanism drives the positioning block 50 to move downward between the upper and lower guide plates 20 to realize the rotation of the shell. Then, the positioning block 50 moves upward for welding. After the welding is completed, the positioning block 50 is reset, and the feeding mechanism 3 removes the processed probe and feeds the shell at the same time.

[0035] See also Figure 2 , Figure 3 and Figure 4The clamping unit 5 includes a positioning block 50, a T-shaped plate 51, a slip ring 52, a support rod 53, a shaft seat 54 and a pressure plate 55. The positioning block 50 is slidably mounted between the two guide plates 20 in the same group above, and the upper end surface of the positioning block 50 is provided with an arc groove. The lower end surface of the positioning block 50 is connected to the switching mechanism. The T-shaped plate 51 is slidably mounted between the two slide grooves 22 in the same group below the positioning block 50. The vertical section of the T-shaped plate 51 is a columnar structure, and the horizontal section of the T-shaped plate 51 is a square structure. The structure is as follows: a stopper is provided on the side wall of the slide groove 22 above the horizontal section of the T-shaped plate 51, a telescopic protrusion is provided on the side wall of the slide groove 22 below the horizontal section of the T-shaped plate 51, a slip ring 52 is rotatably sleeved on the circumferential outer wall of the vertical section of the T-shaped plate 51, and a support rod 53 is symmetrically installed on the circumferential outer wall of the slip ring 52. An axle seat 54 is provided on the end of the support rod 53 away from the slip ring 52. The pressure plate 55 is in a V-shaped structure, the bending part of the pressure plate 55 is hinged to the axle seat 54, and the lower part of the pressure plate 55 is in contact with the positioning block 50.

[0036] During specific operation, when the positioning block 50 moves toward the processing area through the turning unit 6, it will squeeze the lower part of the pressure plate 55, causing its upper part to rotate and extrude the shell to fit and fix with the positioning block 50, so as to avoid uneven gravity distribution after welding of one end of the shell and causing it to tilt and fall, affecting the processing. At the same time, the positioning block 50 and the T-shaped plate 51 are temporarily rotated and matched through the sleeve rod 61 to maintain the pressure plate 55 on the shell, and then move downward synchronously with the positioning block 50. The fixed plate will first slide with the guide plate 20 located below to ensure the stability of the movement of its overall structure, and then the shell will be turned around through the turning mechanism and moved upward to the processing area for processing, and then the positioning block 50 is reset for material replacement processing.

[0037] See also Figure 4 and Figure 5 The upper end of the pressure plate 55 and the arc-shaped groove of the positioning block 50 are both equipped with rollers. During operation, the rollers can reduce the friction between the housing and the pressure plate 55 and the positioning block 50, thereby avoiding reducing the wear of the housing and reducing the external pushing force required by the fixed driving unit 7 to drive the housing to rotate synchronously, so that it can be easily rotated for welding processing.

[0038] See also Figure 3 , Figure 6 and Figure 7The fixed driving unit 7 includes a driving member 70, a truncated cone block 71, a truncated cone pressure block 72, a telescopic cylinder 73, a truncated cone docking block 74, a U-shaped shell 75 and a reset spring 76. The rear side of the guide plate 20 is equipped with a driving member 70 for telescopic rotation through a supporting platform. The driving end of the driving member 70 is equipped with a truncated cone block 71, and a circular hole is opened in the middle of the truncated cone block 71. The truncated cone pressure block 72 is installed in the circular hole through a compression spring. The front side of the support seat is coaxially equipped with a telescopic cylinder 73 and the truncated cone block 71. The telescopic end of the telescopic cylinder 73 extends to the rear side of the support seat. The telescopic end of the telescopic cylinder 73 is equipped with a truncated cone docking block 74. A U-shaped shell 75 with a rear side and an upper end opening is slidably sleeved between the front side end face of the truncated cone docking block 74 and the support seat. The side of the U-shaped shell 75 close to the support seat contacts the blanking square tube 40 , and a return spring 76 is installed between the U-shaped shell 75 and the support seat, and the return spring 76 is sleeved on the telescopic end of the telescopic spring.

[0039] During specific operation, the driving member 70 causes the truncated cone block 71 to move toward the outer shell, and the end of the truncated cone block 71 will be inserted into the outer shell so that it moves coaxially with the truncated cone block 71 and docks with the pressure interface. At the same time, the telescopic end of the telescopic cylinder 73 moves toward the feeding mechanism 4 so that it conflicts with the feeding mechanism 4, and the pressure interface of the feeding mechanism 4 falls into the U-shaped shell 75, and the telescopic cylinder 73 continues to move toward the outer shell position. At this time, due to the conflict between the U-shaped shell 75 and the feeding mechanism 4, the telescopic end of the telescopic cylinder 73 compresses the reset spring 76 and moves toward the pressure interface, so that the end of the truncated cone docking block 74 is inserted into the pressure interface, and at the same time, the pressure interface is pushed to dock and conflict with the outer shell. The driving member 70 drives it to rotate for welding processing. After the welding of one end of the outer shell is completed, the fixed driving unit 7 is reset first and then the reversing processing is performed through the turning unit 6.

[0040] See also Figure 1 , Figure 4 and Figure 5 The turning unit 6 includes an electric telescopic rod 60, a sleeve rod 61, a trapezoidal block 62, a rotating drum 63, a blocking block 64 and a driving steering member 8. The lower end surface of the workbench 1 is equipped with an electric telescopic rod 60, and the telescopic end of the electric telescopic rod 60 is equipped with a sleeve rod 61 through a bearing. The lower circumferential outer wall of the sleeve rod 61 is provided with a limited position convex block. The sleeve rod 61 passes through the workbench 1, the fixed plate and the transition plate in sequence. The upper end of the sleeve rod 61 is fixed to the positioning block 50, and the sleeve rod 61 is connected to the workbench 1 and the T-shaped plate 51. The lower end face of the workbench 1 is provided with a driving steering member 8 which cooperates with the sleeve rod 61 for rotational cooperation. The upper circumferential outer wall of the sleeve rod 61 is provided with a trapezoidal block 62. A rotating cylinder 63 is rotatably installed inside the upper end of the vertical section of the T-shaped rod. The circumferential inner wall of the rotating cylinder 63 and the trapezoidal block 62 are provided with limiting grooves in a one-to-one correspondence. The inner wall of the limiting groove is provided with a blocking block 64 for blocking the trapezoidal block 62 from moving out through a compression spring. The blocking block 64 is L-shaped, and the vertical section of the blocking block 64 is in contact with the T-shaped plate 51.

[0041] During specific operation, the electric telescopic rod 60 drives the sleeve rod 61 to move the positioning block 50 downward, and the trapezoidal block 62 at the upper end of the sleeve rod 61 squeezes the limiting protrusion inward. Since the vertical section of the blocking block 64 resists the T-shaped plate 51 to increase the friction force, and the horizontal section of the blocking block 64 resists the T-shaped plate 51, the trapezoidal block 62 can move to the bottom of the limiting protrusion with the sleeve rod 61. The limiting protrusion limits the up and down movement of the sleeve rod 61 in the vertical section of the T-shaped plate 51 after the spring is reset. At this time, the driving mechanism 2 and the unloading mechanism 4 can be used to cooperate to dock one end of the shell with the pressure interface for welding. After the welding is completed, the sleeve rod 61 continues to move downward and squeezes the blocking block 64 inward through the fixed plate. , the T-shaped plate 51 will first move out and slide with the guide plate 20 below. When the shell moves between the upper and lower guide plates 20, the driving steering member 8 will drive the sleeve rod 61 to rotate 180 degrees, so that the shell is turned around for welding at the other end. Then the positioning block 50 moves upward with the sleeve rod 61, and the horizontal section of the T-shaped plate 51 contacts the limit protrusion and retracts. After the horizontal section of the T-shaped plate 51 moves into the square groove, the shell moves to the processing area for welding. After the processing is completed, the sleeve rod 61 continues to move, and the horizontal section of the T-shaped plate 51 contacts the baffle to separate the T-shaped plate 51 from the trapezoidal block 62. Then the processed probe is moved out by the feeding mechanism 3 and the shell is rolled for continuous processing.

[0042] See also Figure 4 and Figure 8 The driving steering member 8 includes a driven gear 80, a driving gear 81, an inner concave locking arc 82 and an outer convex locking arc 83. The lower end surface of the workbench 1 is coaxially provided with a driven gear 80 and the sleeve rod 61. The lower circumferential outer wall of the sleeve rod 61 is symmetrically provided with a limit bar. The circumferential inner wall of the driven gear 80 and the workbench 1 are provided with square grooves that cooperate with the limit bars. A driving gear 81 is meshed with one side of the driven gear 80. The driven gear 80 and the driving gear 81 are both rotatably matched with the workbench 1, and the driving gear 81 is driven by a motor. The driven gear 80 is composed of a left-right symmetrical No. 1 tooth group and a front-back symmetrical inner concave locking arc 82. The driving gear 81 is composed of a left-right symmetrical No. 2 tooth group and a front-back symmetrical outer convex locking arc 83.

[0043] During specific operation, after the outer shell at one end is moved between the upper and lower guide plates 20, the driving gear 81 is driven by the motor so that the driving gear 81 is placed in the second tooth group and meshes with the first tooth group of the driven gear 80, so that the driven gear 80 drives the sleeve rod 61 to rotate 180 degrees, thereby turning the outer shell around, and then the convex locking arc 83 of the driving gear 81 fits with the concave locking arc 82 of the driven gear 80, and the motor stops driving the driving gear 81, and the convex locking arc 83 of the driving gear 81 fits with the concave locking arc 82 of the driven gear 80 to fix the driven gear 80 to prevent the sleeve rod 61 from moving up and down and deflecting, affecting the cooperation between the T-shaped plate 51 and the guide plate 20.

[0044] Refer to Figure 1 、 Figure 7 and Fig. 9 As shown in, the blanking mechanism 4 includes a blanking square pipe 40, a shield 41 and a partition plate 42. The front side of the guide plate 20 is provided with a blanking square pipe 40 through a support seat. The blanking square pipe 40 is in a Y-shaped structure, and the cross-section of the blanking square pipe 40 is in a cross-shaped structure. A through hole is opened at the bent part of the blanking square pipe 40. A shield 41 is installed at the through hole of the blanking square pipe 40. A partition plate 42 is hinged to the inner wall of the shield 41 through a pin shaft. The partition plate 42 is in a T-shaped structure, and the partition plate 42 is reciprocally swung through a pin shaft in cooperation with a motor.

[0045] During specific operation, after the positioning block 50 moves the housing to the processing area, the motor rotates to drive the partition plate 42 to swing. The vertical section of the partition plate 42 swings to one side of the blanking square pipe 40 to resist the fall of the pressure interface on that side. At the same time, the horizontal section of the partition plate 42 inserts between the pressure interfaces on the other side of the blanking square pipe 40 to separate a pressure interface. Under the action of its own gravity, the pressure interface will move downward and fall into the U-shaped shell 75. Subsequently, the telescopic cylinder 73 docks and fixes the pressure interface with the housing and rotates for welding. Similarly, when the motor drives the partition plate 42 to rotate in the reverse direction, the pressure interface on the other side of the blanking square pipe 40 will fall and be docked with the housing for welding processing.

[0046] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in, the feeding mechanism 3 includes an inclined plate 30, a guiding plate 31, a feed bin 32, a connecting rod 33, a plug plate 34 and a material changing unit 9. An inclined plate 30 that slopes downward to the right is arranged on the upper end surface of the guide plate 20 on the upper left side. A guiding plate 31 is installed on the upper end surface of the guide plate 20 on the upper right side. A feed bin 32 is installed on the side of the guiding plate 31 away from the guide plate 20 through a support frame. A connecting rod 33 is hinged to the front and rear lower end surfaces of the guiding plate 31 through a shaft plate and a torsion spring respectively. Waist holes are opened at both ends of the connecting rod 33. A plug plate 34 is hinged between the two waist holes of the two connecting rods 33 that face each other front and back. The plug plate 34 is in a U-shaped structure. The vertical section of the plug plate 34 is slidably matched with the guiding plate 31. A material changing unit 9 is arranged on the front side of the guide plate 20.

[0047] During specific work, the processed probe is moved upward by the electric telescopic rod 60 to reset the probe to the initial position, and then the probe is lifted by the operation of the material changing unit 9. The probe will roll along the inclined plate 30 for centralized collection and processing. Then, while the material changing unit 9 is reset, the connecting rod 33 is rotated to make the plug plate 34 on the left slide away from the guide plate 31, so that the shell can roll into the arc-shaped groove of the positioning block 50, and at the same time, the plug plate 34 on the right will move up to block the rolling of the shell behind, thereby ensuring the orderly rolling processing of the shell, and then the plug plate 34 on the left moves up and the plug plate 34 on the right moves down, and the shell rolls to the right side of the plug plate 34 to wait for falling processing.

[0048] See also Figure 2 and Figure 3 The material changing unit 9 includes a shaft rod 90, a guide rod 91 and a driving plate 92. The shaft rod 90 is rotatably installed on the side of the inclined plate 30 close to the directional block, and the two ends of the shaft rod 90 extend to the outside of the inclined plate 30. The shaft heads at both ends of the shaft rod 90 are installed with a material lifting turntable, and the circumferential outer wall of the material lifting turntable is provided with a guide rod 91. The shaft rod 90 is driven by a motor, and a driving plate 92 is symmetrically provided on the front and rear end surfaces of the guide plate 31. The side of the driving plate 92 close to the positioning block 50 is hinged to the guide plate 31 through a pin shaft, and the end face of the driving plate 92 away from the positioning block 50 is hinged to the plug plate 34 on the right side of the connecting rod 33. The other side of the driving plate 92 is in conflict with the guide rod 91, and waist-shaped holes are provided at the hinges of the driving plate 92 and the guide plate 31 and the plug plate 34.

[0049] After the plug plate 34 on the right side of the connecting rod 33 moves into place, the guide rod 91 will push the driving plate 92 away from the guide rod 91, and then the connecting rod 33 will rotate under the action of the torsion spring, thereby resetting the plug plates 34 at both ends.

[0050] When the present invention is used to process a mining differential pressure sensor, the material bin 32 and the material discharge square tube 40 are manually loaded first, and then the feeding mechanism 3 will continuously send the shell to the positioning block 50. Then the positioning block 50 is first moved downward by the electric telescopic rod 60 to contact the lower part of the pressure plate 55 so that its upper part squeezes the shell and fixes it on the positioning block 50. Then the fixed driving unit 7 pushes the pressure interface to dock with the shell and contact it, so that it rotates for welding processing. Then the positioning block 50 moves down to between the upper and lower guide plates 20 and drives the steering member 8 to drive the positioning block 50 to rotate 180 degrees to realize the shell turning and then moving up for processing. After the processing is completed, it is reset and the processed probe is lifted and guided to fall by the material changing unit 9 for centralized collection. At the same time, the feeding mechanism 3 is driven to discharge the material to realize continuous processing and improve the processing efficiency.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
