Description

Technical Field

[0001] The present invention relates to the technical field of pressure gauge production, and particularly to a screwing and assembling device for a diaphragm pressure gauge. Background Art

[0002] A diaphragm pressure gauge consists of a diaphragm seal and a pressure gauge to form an integral diaphragm gauge. Through a special device, the bourdon tube in the pressure gauge is evacuated and filled with a working fluid, which is sealed and isolated by a diaphragm. When the pressure P of the measured medium acts on the diaphragm and causes the diaphragm to deform, it will compress the working fluid filled inside the system, making the working fluid form a ΔP equivalent to P. With the conduction of the working fluid, the free end of the elastic element (bourdon tube) in the pressure gauge will generate a corresponding elastic deformation displacement, and then the generated deformation is presented in the form of a pointer through a conduction member, so as to facilitate the staff to read the pressure of the medium; the diaphragm pressure gauge is suitable for measuring the pressure of media with strong corrosion, high temperature, high viscosity, easy crystallization, easy solidification, solid floating matter, and occasions where it is necessary to avoid the measured medium directly entering a general-purpose pressure gauge and prevent sediment accumulation and is easy to clean;

[0003] The diaphragm pressure gauge mainly consists of a diaphragm seal and a pressure instrument. During the production process, the two are mainly connected by a spiral fit. In the current production of pressure gauges, the screwing of the two is mainly operated manually, but such an operation method has the disadvantages of high labor intensity and low production efficiency;

[0004] Of course, after searching the existing public documents CN109396817A - A screwing device and the existing public document CN112223176A - A pressure gauge housing assembly tooling, both disclose an assembly device applicable to the screwing of instruments. The above screwing devices drive the rotation and tightening between the fittings by abutting against the end of the fitting through friction. However, in actual use, due to the existence of the diaphragm at the end of the diaphragm seal, such a rotation and tightening method will cause damage to the diaphragm when applied to the screwing of the diaphragm pressure gauge, thereby reducing the quality of the pressure gauge and affecting the service life of the pressure gauge;

[0005] Therefore, it is necessary to improve the existing technology to solve the above technical problems. Summary of the Invention

[0006] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the specification of this application, to avoid obscuring the purpose of this part, the abstract of the specification, and the title of the invention. However, such simplifications or omissions cannot be used to limit the scope of the present invention.

[0007] In view of the fact that the above-mentioned existing diaphragm pressure gauges need to be tightened manually by workers during the production process, which results in low production efficiency and high labor intensity, a diaphragm pressure gauge tightening and assembly device is proposed.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions: a diaphragm pressure gauge tightening and assembly device, including a base plate feeding mechanism, including a first conveying component, guide belts symmetrically arranged on both sides of the first conveying component and a screwing component arranged at the output end of the first conveying component, the screwing component including an outer protective box, a screwing disk and a second cylinder, the outer protective box is arranged with an opening at the lower end, and the screwing disk is embedded in the outer protective box, an output shaft is fixedly provided in the middle of the screwing disk, and a second cylinder with an axis parallel to the conveying direction of the first conveying component is fixedly provided on the top surface of the outer protective box, and the two guide belts cooperate to limit the base plate to realize the base plate when moving The axis always remains parallel to the axis of the output shaft; and the display disk feeding mechanism arranged on the other side of the screwing component includes a second feeding component and a discharge barrel arranged below the output end of the second feeding component, and the discharge barrel is arranged on the side close to the screwing component, and a guide groove with an open lower end is provided in the vertical direction on the side surface of the discharge barrel close to the screwing component, and the axis of the display disk located in the discharge barrel is upward and coaxially arranged with the discharge barrel; a tray is coaxially arranged below the discharge barrel, and the lower end of the discharge barrel is opened and closed by the withdrawal movement of the first conveying component to realize the movement of the tray in the horizontal direction, and the withdrawal movement of the first conveying component is along the feeding direction of the first conveying component.

[0009] The beneficial effects of the present invention are as follows: when the tightening and assembly equipment is in use, the diaphragm seal is transported to the screwing assembly position through the first conveying assembly, and the pressure instrument is transported to the screwing assembly position through the second feeding assembly. After the pressure instrument is input into the discharge barrel by the second conveying assembly, the threaded connecting rod on the pressure instrument is inserted and passed through the guide groove, and finally falls on the pallet. When the diaphragm seal is transported to one side of the screwing assembly by the first conveying assembly, the threaded connecting sleeve on the diaphragm seal finally abuts against the free end of the connecting rod, and then the second cylinder drives the screwing assembly to move downward, and the screwing disk abuts against the side wall of the diaphragm seal. Through the rotation of the screwing disk, due to the existence of friction, the diaphragm seal will also rotate synchronously, and finally the connecting sleeve is spirally fitted on the connecting rod to complete the screwing assembly between the diaphragm seal and the pressure instrument. The tightening and assembly equipment only needs to place the various accessories on the first conveying assembly and the second conveying assembly to realize subsequent automatic assembly. It has good overall practicality, can effectively reduce the labor intensity of the staff, and improve production efficiency.

[0015] Another beneficial effect of the present invention is as follows: When the tightening and assembling device is in use, when the diaphragm seal is conveyed on the first conveying component, the diaphragm seal will be inserted between the two clamping plates in the same group for positioning.

[0033] Embodiment 1

[0034] Referring to Figure 1 、 Figure 2 and Figure 3 , it is the first embodiment of the present invention. This embodiment provides a screwing and assembling device for a diaphragm pressure gauge. When the screwing and assembling device is in use, the base plate feeding mechanism 100 is used for the automatic feeding of diaphragm seals, the display plate feeding mechanism 200 is used for the automatic feeding of pressure gauges. After the diaphragm seal and the pressure gauge are matched, they are screwed and assembled through the screwing component 103, and finally, they are automatically conveyed out through the discharging mechanism 300.

[0035] Specifically, it includes a base plate feeding mechanism 100, which includes a first conveying component 101, guiding belts 102 symmetrically arranged on both sides of the first conveying component 101, and a screwing component 103 arranged at the output end of the first conveying component 101; a display plate feeding mechanism 200 arranged on the other side of the screwing component 103, which includes a second feeding component and a feeding cylinder 202 arranged below the output end of the second feeding component, and the feeding cylinder 202 is arranged on the side close to the screwing component 103; and a discharging mechanism 300, which includes a third conveying component 301 located below the second conveying component 201 and a base plate 302 located below the third conveying component 301.

[0036] See in detail Figure 3 and Figure 6As shown in the figure, the first conveying assembly 101 includes a first conveyor belt 101a, a first outer guard 101b located outside the lower end of the first conveyor belt 101a, and a first roller 101d slidably sleeved at both ends of the first conveyor belt 101a. A first rotating shaft 101d-1 is fixedly sleeved in the first roller 101d, and both ends of the first rotating shaft 101d-1 are rotatably sleeved on the first outer guard 101b through rolling bearings. One end of one of the first rotating shafts 101d-1 extends outside the first outer guard 101b and is fitted into the output end of the first motor 101d-2, and the first motor 101d-2 is fixedly arranged on the outer side wall of the first outer guard 101b. When in use, through the operation of the first motor 101d-2, the first rotating shaft 101d-1 can drive the first roller 101d to rotate, and finally the first conveyor belt 101a conveys the diaphragm seal to the screwing assembly 103.

[0037] See details in Figure 4 and Figure 8 As shown in the figure, the second conveying assembly 201 includes a second conveyor belt 201a, a second outer guard 201b arranged outside the second conveyor belt 201a, and a second roller 201c slidably sleeved at both ends of the second conveyor belt 201a. A second rotating shaft 201c-1 is fixedly sleeved in the second roller 201c, and both ends of the second rotating shaft 201c-1 are rotatably sleeved on the second outer guard 201b through rolling bearings. One end of one of the second rotating shafts 201c-1 extends outside the second outer guard 201b and is fitted into the output end of the second motor 201c-2, and the second motor 201c-2 is fixedly arranged on the outer side wall of the second outer guard 201b. When in use, through the operation of the second motor 201c-2, the second rotating shaft 201c-1 can drive the second roller 201c to rotate, and finally the second conveyor belt 201a conveys the pressure gauge to the discharging cylinder 202.

[0038] See details in Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the screwing assembly 103 includes an outer protective box 103a, a screwing disc 103b, and a second cylinder 103c. The outer protective box 103a is provided with an open lower end, and the screwing disc 103b is fitted in the outer protective box 103a. An output shaft 103b-1 with an axis parallel to the conveying direction of the first conveying assembly 101 is fixedly provided in the middle of the screwing disc 103b. Both ends of the output shaft 103b-1 are rotatably sleeved on the outer protective box 103a through rolling bearings. One end of the output shaft 103b-1 extends to the outside of the outer protective box 103a and is fitted in the output end of the fourth motor 103b-2, and the fourth motor 103b-2 is fixedly connected to the outer side wall of the outer protective box 103a. By the operation of the fourth motor 103b-2, the rotation of the output shaft 103b-1 can be realized, and finally the rotation of the screwing disc 103b can be realized;

[0039] A second cylinder 103c with a vertical telescopic direction is fixedly provided on the top surface of the outer protective box 103a. Extension plates 103a-1 are symmetrically fixedly provided on both sides of the top surface of the outer protective box 103a, and T-shaped rods 103a-2 are fixedly provided on the top surfaces of the extension plates 103a-1. The fixed section of the second cylinder 103c is fixedly connected to the top surface of the base plate 302 through a U-shaped frame 302a, and the free end of the T-shaped rod 103a-2 is slidably sleeved on the U-shaped frame 302a. The setting of the T-shaped rod 103a-2 can realize the limit guidance for the movement of the second cylinder 103c;

[0040] A guiding groove 202c with an open lower end is vertically opened on one side of the feeding cylinder 202 close to the screwing assembly 103. The guiding groove 202c is provided for the connecting rod of the pressure gauge to pass through. The axis of the display disc (i.e., the pressure gauge) located in the feeding cylinder 202 is upward and coaxial with the feeding cylinder 202. A tray 202a is coaxially provided below the feeding cylinder 202;

[0041] When the above settings are in use, the pressure gauges conveyed by the second conveying assembly 201 finally fall into the feeding cylinder 202 and are placed on the tray 202a. At this time, the connecting rod on the pressure gauge is penetrated and fitted in the guiding groove 202c. The diaphragm seals conveyed by the first conveying assembly 101 are conveyed towards the position of the feeding cylinder 202. Finally, the connecting sleeve on the diaphragm seal abuts against the free end of the connecting rod of the pressure gauge. At this time, driven by the extension of the second cylinder 103c, the screwing disc 103b abuts against the side wall of the diaphragm seal. Through the operation of the fourth motor 103b-2, the screwing disc 103b starts to rotate. Under the action of the frictional force between the screwing disc 103b and the diaphragm seal in contact, the diaphragm seal will rotate synchronously, and finally the automatic spiral fitting between the connecting sleeve on the diaphragm seal and the connecting rod on the pressure gauge is realized.

[0042] Further, the discharging movement of the first conveying component 101 is used to move the tray 202a horizontally to open and close the lower end of the discharging cylinder 202, and the discharging movement of the first conveying component 101 is along the material conveying direction of the first conveying component 101. Therefore, when the first conveying component 101 makes a discharging action, the tray 202a will open from the lower end of the discharging cylinder 202, realizing the discharging of the assembled diaphragm pressure gauge.

[0043] Further, the two guiding belts 102 cooperate with and limit the base plate to ensure that the axis of the base plate (i.e., the diaphragm seal) always remains parallel to the axis of the output shaft 103b-1 during movement, so as to realize the coaxial alignment and abutment of the connecting sleeve on the diaphragm seal and the connecting rod on the pressure gauge. On both sides of the bottom surface of the outer protection box 103a, there are symmetrically downwardly extending and fixedly arranged limiting plates 103a-3. When the diaphragm seal rotates, the limiting plates 103a-3 can limit the diaphragm seal from the side.

[0044] See Figure 4 and Figure 9 As shown, the third conveying component 301 includes a third conveyor belt 301a, a third outer protection frame 301b located outside the third conveyor belt 301a, and third rollers 301c slidably sleeved at both ends of the third conveyor belt 301a. A third rotating shaft 301c-1 is fixedly sleeved in the third roller 301c, and both ends of the third rotating shaft 301c-1 are rotatably sleeved on the third outer protection frame 301b through rolling bearings. One end of one of the third rotating shafts 301c-1 extends outside the third outer protection frame 301b and is fitted into the output end of the third motor 301c-2, and the third motor 301c-2 is fixedly arranged on the outer side wall of the third outer protection frame 301b. In the above setting, when in use, the assembled diaphragm pressure gauge falls onto the third conveyor belt 301a after discharging. By the operation of the third motor 301c-2, the third rotating shaft 301c-1 drives the third roller 301c to rotate, and finally the third conveyor belt 301a conveys the diaphragm pressure gauge out.

[0045] Further, the second outer protection frame 201b and the third outer protection frame 301b are fixedly connected, and the third outer protection frame 301b is also fixedly connected to the base plate 302.

[0046] In addition, it should be noted that this device also includes a controller (not shown in the drawings) for controlling various electrical components. The controller is set at a position convenient for the staff to operate. In addition, in order to accurately convey the diaphragm seal and the pressure gauge one by one, an induction module and a counting module should be set on the first conveying component 101 and the second conveying component 201 to realize the induction and counting of materials, and finally realize the one-to-one conveying and assembly of the diaphragm seal and the pressure gauge.

[0047] Embodiment 2

[0048] Reference Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 and Figure 9 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that in order to more conveniently implement the present invention and improve the automation degree of the device, the discharging action of the diaphragm pressure gauge after assembly and the structure required for discharging are described in detail.

[0049] Specifically, a linkage plate 101b-1 is fixedly provided on the inner top surface of one end of the first outer guard frame 101b away from the screwing assembly 103, and a first cylinder 101b-3 is fixedly provided at one end of the linkage plate 101b-1 away from the screwing assembly 103; a movable ear 202a-1 is fixedly provided on one side surface of the tray 202a away from the screwing assembly 103, and the top surface of the movable ear 202a-1 is fixedly connected to a gear disk 202a-2 through a connecting column 202a-3. A rack plate 101c-1 is meshed on one side of the gear disk 202a-2, and the rack plate 101c-1 is fixedly connected to the outer side wall of the first outer guard frame 101b through a linkage frame 101c. A fixed ear 202b for slidably sleeving the connecting column 202a-3 is fixedly provided on the outer side wall of the feeding cylinder 202.

[0050] When the above settings are in use, after the diaphragm pressure gauge is assembled, by the contraction of the first cylinder 101b-3, the first conveying assembly 101 can be moved in a direction away from the screwing assembly 103, so that the diaphragm pressure gauge can be gradually separated from the first conveyor belt 101a. While the first conveying assembly 101 is moving, the linkage frame 101c will also drive the rack plate 101c-1 to move. Also, due to the meshing setting between the rack plate 101c-1 and the gear disk 202a-2, finally, the gear disk 202a-2 drives the tray 202a to rotate around the connecting column 202a-3, and the lower end of the feeding cylinder 202 is opened, and the assembled diaphragm pressure gauge finally falls onto the third conveyor belt 301a.

[0051] Furthermore, a sliding groove 101b-2 is opened on the bottom surface of the linkage plate 101b-1 along the conveying direction of the first conveying assembly 101, and a guide slider 302b for clearance fit with the sliding groove 101b-2 is fixedly provided on the top surface of the base plate 302. This setting can play a role in limiting and guiding the movement of the first outer guard frame 101b. An oil filling groove 302b-1 is opened on the top surface of the guide slider 302b along the conveying direction, and the oil filling groove 302b-1 is filled with lubricating oil to reduce the frictional force of the fit. The fixed section of the first cylinder 101b-3 is fixedly connected to the top surface of the base plate 302.

[0052] Embodiment 3

[0053] ReferenceFigure 1 , Figure 4 and Figure 6 , which is the third embodiment of the present invention. This embodiment is based on any of the above embodiments. The difference is that in order to ensure that the axis of the connecting sleeve of the diaphragm seal always remains parallel to the axis of the output shaft 103b-1 when the first conveying component 101 conveys the diaphragm seal, this embodiment is proposed.

[0054] Specifically, auxiliary roller cylinders 102b are slidably sleeved on the inner sides of both ends of the guiding belt 102, and auxiliary rotating columns 102b-1 with a vertical axis are fixedly sleeved in the auxiliary roller cylinders 102b. Both ends of the auxiliary rotating column 102b-1 are rotatably connected to the first outer guard frame 101b and the auxiliary guard frame 102c through rolling bearings respectively. This setting can enable the auxiliary roller cylinder 102b to drive the guiding belt 102 for conveying, and the auxiliary guard frame 102c is fixedly connected to the outer side wall of the first outer guard frame 101b; a plurality of groups of clamping plates 102a are fixedly arranged on the outer side wall of the guiding belt 102 in an array along the conveying direction, and the two clamping plates 102a in each group are arranged in a "‖" shape.

[0055] When the above setting is in use, the two clamping plates 102a in the same group are arranged in a "‖" shape, and the diaphragm seal is inserted into the middle position of the "‖" shape to realize the limit of the diaphragm seal. When the first conveyor belt 101a drives the diaphragm seal to move, the two clamping plates 102a in the same group will move synchronously for limiting. As the first conveyor belt 101a continues to convey, when the guiding belt 102 moves to the position of the auxiliary roller cylinder 102b, one of the clamping plates 102 loses the limit on the diaphragm seal due to the change in the moving direction, and at this time, the diaphragm seal can automatically disengage from the first conveying component 101.

[0056] Embodiment 4

[0057] Referring to Figure 8 , which is the fourth embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that in order to avoid the connecting rod on the pressure gauge from not accurately entering the guiding groove 202c when the second conveying component 201 conveys the pressure gauge, this embodiment is proposed to adjust the state of the pressure gauge on the second conveying component 201.

[0058] Specifically, correction plates 201d are symmetrically arranged on both sides above one end of the second conveyor belt 201a close to the feeding cylinder 202. A third cylinder 201d-1 is fixedly connected to one side surface of the correction plate 201d, and the fixed section of the third cylinder 201d-1 slidably passes through the second outer guard 201b and is fixedly connected to the outer side wall of the second outer guard 201b through a fixing bracket 201d-2. When in use, when the pressure gauge on the second conveyor belt 201a moves towards the feeding cylinder 202, the synchronous extension of the two third cylinders 201d-1 will cause the two correction plates 201d to move towards each other. The movement of the two correction plates 201d towards each other will push the connecting rod on the pressure gauge, so as to adjust the position of the connecting rod, facilitating the insertion of the connecting rod into the guiding groove 202c.

[0059] Furthermore, one end of the second outer guard 201b is fixedly connected to the upper end position of one side wall of the feeding cylinder 202, and the inner width dimension of the second outer guard 201b is equal to the inner wall diameter dimension of the feeding cylinder 202, so as to enable the pressure gauge to accurately enter the feeding cylinder 202.
