Description

Technical Field

[0001] The present application relates to the technical field of pressure gauge production welding, and more specifically, to a pressure gauge movement welding device. Background Art

[0002] The pressure gauge is mainly composed of a case, a dial, a pointer, a sensor, an internal mechanism (pressure gauge movement, etc.), a joint, a filling medium, and electrical components. These parts work together to measure and display the pressure value of the medium. Among them, the pressure gauge movement needs to carry the installation and fixation of the pointer, gears, and levers to achieve the normal operation of the pressure gauge. In the process of producing the pressure gauge, some parts in the movement need to be welded to ensure the integrity of the movement.

[0003] After searching, the announcement number is CN211728029U, which discloses a pressure gauge movement welding device, including a cleaning plate. The movement of the cleaning plate drives the slider to move along the guide rod. The movement of the slider stretches spring one, so that spring one generates elastic force. The cleaning plate moves and slides relative to the top of the workbench, thereby cleaning the workbench. The elastic force of spring one facilitates the movement and reset of the slider and the cleaning plate. The welding head is inserted into the cylindrical through hole. The movement of the welding head drives the movement of the mounting ring. The movement of the mounting ring squeezes the clamping block, so that the clamping block moves to squeeze the spring two. The spring two is squeezed and generates elastic force. When the mounting ring passes over the conical inclined surface, the clamping block moves and fits with the mounting ring under the action of the elastic force of the spring two, thereby clamping and fixing the welding head, so as to solve the problem that the welding slag generated during the welding process falls on the workbench and is inconvenient to clean. At the same time, there is a lack of a clamping mechanism, which makes it inconvenient to clamp and store the welding head.

[0004] However, the movement of the existing pressure gauge is often composed of a Bourdon tube, gears and levers. When producing the movement, in order to ensure the sealing of one end of the Bourdon tube, one end of the Bourdon tube needs to be welded. The Bourdon tube is a C-shaped hollow structure. During the welding process, it needs to be manually installed on the fixture, and then one end of the Bourdon tube is sealed and welded by a argon arc welding machine. This will lead to the situation that the Bourdon tube is not easy to position during loading, resulting in irregular welding joints.

[0005] Therefore, it is necessary to provide a pressure gauge movement welding device to solve the above problems.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0025] See also Figure 1-10 , the embodiment provided by the present invention: Example 1

[0026] like Figure 1 , Figure 6 and Figure 7 As shown, a pressure gauge movement welding device comprises a workbench 1, a spindle seat 4 is fixedly installed at the center of the top surface of the workbench 1, a rotating disc 2 for placing a C-shaped Bourdon tube is rotatably connected to the shaft of the spindle seat 4, the C-shaped Bourdon tube placed on the rotating disc 2 is transferred by the rotation of the rotating disc 2, and the welding of the C-shaped Bourdon tube is realized, and a clamp 7 for clamping the C-shaped Bourdon tube is respectively installed at equal angles on a circle of the top surface of the rotating disc 2. In order to fix the special shape of the C-shaped Bourdon tube and ensure that one end of the C-shaped Bourdon tube can be opened upward for easy welding, the clamp 7 comprises a fixing seat 71, a pressing plate 77 and a clamping seat 72, the fixing seat 71 is respectively fixedly installed on a circle of the top surface of the rotating disc, the clamping seat 72 is fixedly installed on the top surface of the fixing seat 71, and the C-shaped Bourdon tube is clamped and fixed by the clamping seat 72; Specifically, Figure 6 and Figure 7 As shown, a semicircular groove 73 is provided on the top surface of the clamp seat 72, and a fixed plate 74 is installed on one side of the semicircular groove 73. A buffer pad 75 is bonded to the outer side of the fixed plate 74. The buffer pad 75 is provided to reduce the surface wear caused by the C-shaped Bourdon tube when clamping. Rotation grooves 76 are provided on both sides of the semicircular groove 73, and one end of the pressure plate 77 is rotatably connected in the rotation groove 76 through an axle rod. A support rod 78 is obliquely fixed to the bottom surface of the pressure plate 77, and a bracket 79 is rotatably connected to the bottom end of the support rod 78 through a pin shaft. The bottom surface of the bracket 79 is fixedly installed with the telescopic shaft of the cylinder 710, and the cylinder 710 is rotatably installed on the bottom surface of the mounting frame 711 through a support. The mounting frame 711 is fixedly installed on the bottom surface of the rotating material tray 2, and the rotating material tray 2 is provided with a first slot 21 at the position of the bracket 79, and the bracket 79 is slidably connected to the inside of the first slot 21.

[0027] The two ends of the C-shaped Bourdon tube are opened upward and placed in the semicircular groove 73, and the side wall of the C-shaped Bourdon tube is in contact with the buffer pad 75 on the fixed plate 74. Then, the telescopic shaft of the control cylinder 710 is extended to push the bracket 79 upward, so that the bracket 79 creates a force with the support rod 78 through rotation. Since the support rod 78 and the pressure plate 77 are arranged at an angle, when the telescopic shaft of the cylinder 710 is extended, the bracket 79 is pushed to move upward, and the support rod 78 pushes the pressure plate 77 to rotate along the fixed shaft rod at one end. At the same time, the bracket 79 and the cylinder 710 can rotate on the mounting frame 711 through the support, so that the pressure plate 77 can act on the other side of the C-shaped Bourdon tube and clamp the C-shaped Bourdon tube between the fixed plate 74 and the two pressure plates 77 to be fixed, so that the welding process can be better performed.

[0028] Furthermore, a corrugated buffer pad 75 is provided on the rotating plate 33, which can reduce the surface wear of the C-shaped Bourdon tube caused by clamping on the one hand, and prevent the position of the C-shaped Bourdon tube from moving when clamping on the other hand. Example 2

[0029] On the basis of Example 1, the following improvements are made to solve the problem of the fixed-angle rotation of the rotating disc 2, so as to facilitate the subsequent automatic loading and welding of the C-shaped Bourdon tube and optimize the processing.

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a positioning assembly 5 for controlling the rotation angle of the rotating material tray 2 is fixedly installed on the bottom surface of the rotating material tray 2, and an intermittent adjustment assembly 3 for adjusting the rotation angle of the rotating material tray 2 is fixedly installed on the bottom surface of the positioning assembly 5 by screws; Specifically, if Figure 5 As shown, the positioning assembly 5 includes a positioning plate 51 and an inserting plate 53. The side walls of the positioning plate 51 are respectively provided with notches 52 according to the position of the clamp 7. One end of the inserting plate 53 is set as a protrusion, which is plugged into any one of the multiple notches 52. An axial hole is opened on the central top surface of the inserting plate 53. A second fixed shaft 54 ​​is rotatably connected in the axial hole. The bottom surface of the second fixed shaft 54 ​​is installed on the workbench 1. The other end of the inserting plate 53 is rotatably connected to a second inserting rod 55 through a pin shaft. The tail of the second inserting rod 55 is fixedly installed with the telescopic shaft of the second electric push rod 56. The tail of the second electric push rod 56 is installed on the top surface of the workbench 1 through a hinge seat. Figure 4As shown, the intermittent adjustment assembly 3 includes a ratchet 31 and a ratchet tooth 35. The bottom surface of the positioning plate 51 is fixedly installed with the top surface of the ratchet 31 by screws. The side wall tooth groove of the ratchet 31 is clamped with one end of the ratchet tooth 35. The center of the ratchet tooth 35 is provided with an axial hole, which is rotatably connected with the side wall of the first fixed shaft 34. The bottom surface of the first fixed shaft 34 is fixedly installed with a rotating plate 33. The other end of the ratchet tooth 35 is hung with one end of the spring 36 through a hook. The other end of the spring 36 is mounted on the rotating plate through a hook. On the top surface of the rotating plate 33, the top end of the rotating plate 33 is fixedly connected with a rotating drum 32, and the rotating drum 32 is rotatably connected to the side wall of the shaft of the spindle seat 4. The top surface of the workbench 1 is provided with an annular groove 11, and the side wall of the rotating plate 33 is slidably connected in the annular groove 11. The bottom end of the rotating plate 33 is rotatably connected to one end of the first plug rod 37 through a pin shaft, and the other end of the first plug rod 37 is fixedly installed with the telescopic shaft of the first electric push rod 38. The first electric push rod 38 is fixedly installed on the bottom surface of the workbench 1 through a hinge seat; In order to enable the rotating disc 2 to intermittently rotate at a specified angle according to the position of the clamp 7 installed on the rotating disc 2, first, the telescopic axis of the second electric push rod 56 of the positioning assembly 5 is extended or shortened to drive the other end of the plug plate 53 to rotate on the second fixed axis 54. During the rotation, the protrusion on the end of the plug plate 53 can be pulled out and inserted into the notch 52 on the side wall of the positioning disc 51. When inserted, the positioning disc 51 is locked, so that the rotating disc 2 can maintain the current position fixed. When the protrusion is pulled out, the rotating disc 2 can rotate freely on the spindle seat 4, thereby positioning the rotation angle of the rotating disc 2.

[0031] Secondly, in order to drive the rotating material tray 2 to intermittently move according to the position of the clamp 7 on the rotating material tray 2, the telescopic shaft of the first electric push rod 38 is extended or shortened, so that the bottom of the rotating plate 33 can be driven to rotate on the first plug rod 37, and under the action of the rotating cylinder 32, it reciprocates along the axis of the main shaft seat 4. During the movement of the rotating plate 33, the elastic force of the spring 36 on the top surface of the rotating plate 33 is changed, and the spring 36 is driven to pull the other end of the ratchet 35 or not pull it, so that the ratchet 35 It can rotate back and forth on the first fixed shaft 34, so that one end of the ratchet 35 is pushed back and forth in the tooth groove on the side wall of the ratchet 31, thereby driving the ratchet 31 to rotate intermittently. Since the ratchet 31 is fixedly installed with the positioning plate 51, when the positioning plate 51 is restricted by contact, the rotating plate 2 can rotate intermittently according to the intermittent movement of the ratchet 31, and then switch the position of the clamp 7, so as to achieve intermittent rotation of the rotating plate 2, so as to provide switching of the clamp 7 for the subsequent automatic loading and welding of the C-shaped Bourdon tube.

[0032] As a further optimization solution of this embodiment 2, Figure 3As shown, a limit assembly 6 is provided on the bottom surface of the rotating material tray 2 along the periphery of the intermittent adjustment assembly 3 and the positioning assembly 5. The limit assembly 6 includes a limit groove 61, a support plate 62 and a guide wheel 63. The limit groove 61 is surrounded by two limit rings of different diameters. The guide wheel 63 is slidably connected in the limit groove 61. The guide wheel 63 is rotatably connected to the top side wall of the support plate 62. The support plate 62 is fixed on the top surface of the workbench 1 by screws. The guide wheel 63 slides in the limit groove 61 to ensure that the rotating material tray 2 keeps rotating along the axis, thereby ensuring that the position of each fixture 7 installed thereon is positioned during the rotation process. Example 3

[0033] like Figure 8 and Fig. 9 As shown, on the basis of Example 1 and Example 2, it is necessary to automatically load and weld the C-shaped Bourdon tube to be welded, and the automatic loading process is realized by the designed loading assembly 8, and the automatic welding process of the C-shaped Bourdon tube is realized by the industrial robot 9.

[0034] Specifically, the discharge port of the loading assembly 8 is located at the open end of the semicircular groove 73. The loading assembly 8 includes a material storage mechanism and a material guide mechanism. The material guide mechanism pushes the C-shaped Bourdon tubes stored in the material storage mechanism into the semicircular groove 73 of the clamp seat 72 one by one through the push plate 88. like Figure 8 As shown, the material storage mechanism includes a silo 81, and a feed silo 81 is integrally formed on the top surface of the silo 81. The top surface of the feed silo 81 is set as a feed port 82, and the bottom surface of the feed silo 81 is fixedly connected to the material guiding mechanism. C-shaped Bourdon tubes are put into the feed silo 81 one by one through the feed port 82 of the feed silo 81, so that a plurality of C-shaped Bourdon tubes are vertically arranged in the silo 81, waiting for the material guiding mechanism to load the fixture 7.

[0035] like Fig. 9 As shown, the material guiding mechanism includes a material guiding tube 83, a guide plate 84, a baffle 86, a push plate 88 and a third electric push rod 87. The bottom surface of the silo 81 is fixedly connected to the rear surface of the material guiding tube 83 and is internally conductive. A slide groove 85 is provided on the surface of the material guiding tube 83. Second slots 89 are provided on both sides of the slide groove 85. The plug plate 53 is slidably connected in the second slot 89. The rear bottom surface of the plug plate 53 is fixedly installed with a connecting block 810. The connecting block 810 is fixedly connected to the surface of the guide rod 811. The connecting block 810 is slidably connected in the slide groove 85. The rear end of the guide rod 811 is fixedly installed with the telescopic shaft of the third electric push rod 87. The end of the guide rod 811 is fixedly installed with the outer side of the push plate 88. The guide plate 84 is integrally formed inside the material outlet of the material guiding tube 83.

[0036] The third electric push rod 87 drives the guide rod 811 to move telescopically, so that the plug plate 53 moves back and forth in the slot. During the back and forth movement, the C-shaped Bourdon tubes enter the guide tube 83 one by one from the silo 81. At the same time, in this process, the push plate 88 pushes each C-shaped Bourdon tube that enters the guide tube 83, and pushes the C-shaped Bourdon tube into the semicircular groove 73 of the clamp seat 72, so as to realize the loading processing of the C-shaped Bourdon tube instead of manual installation. Driven by the connecting block 810, the plug plate 53 can move back and forth in the slide groove 85 and the slot respectively as the push plate 88 pushes, so as to realize the isolation of the C-shaped Bourdon tube.

[0037] In order to better load the C-shaped Bourdon tube with its opening upward, a tapered portion 841 is integrally formed on the inner side of the guide plate 84, and a spherical groove 842 is provided at the end of the tapered portion 841. The guide plate 84 and the discharge port of the guide tube 83 together form a "C"-shaped discharge trough. Through the "C"-shaped discharge trough, the C-shaped Bourdon tube can pass through the tapered portion 841 of the guide plate 84 to ensure that the opening of the C-shaped Bourdon tube is pushed out of the "C"-shaped discharge trough upward. In order to ensure that the C-shaped Bourdon tube on the semicircular groove 73 can maintain an open-upward posture to facilitate the sealing welding of the open mouth, a hemisphere 882 is integrally formed at the inner center of the push plate 88, and the hemisphere 882 can be plugged into the spherical groove 842. A semi-ring portion 881 is integrally formed near the edge of the inner side of the push plate 88, and the semi-ring portion 881 can be plugged into the discharge trough. The design of the hemisphere 882 ensures that the center of the C-shaped Bourdon tube can be mounted on the hemisphere 882, and the semi-ring portion 881 can enable the C-shaped Bourdon tube to be discharged from the "C"-shaped discharge trough to prevent blockage.

[0038] like Figure 1 and Fig.10 As shown, the intermittent rotation of the rotating disc 2 is driven by the intermittent adjustment component 3. After each fixture 7 passes through the loading component 8 and is loaded with a C-shaped Bourdon tube by the material guide mechanism, it can be rotated to the welding area of ​​the industrial robot 9. A welding gun head 10 for welding the C-shaped Bourdon tube is installed at the end of the industrial robot 9. The industrial robot 9 is fixedly installed on the top surface of the workbench 1 and is symmetrically arranged with the loading component 8 with the rotating disc 2 as the center. The industrial robot 9 adopts a five-axis robot. The movement of the robot drives the welding gun head 10 to move, so as to perform a sealing welding process on one of the openings of the C-shaped Bourdon tube, thereby achieving an automatic welding process.
