Description

Technical Field

[0001] This invention belongs to the field of gas meter manufacturing equipment, specifically relating to a vertical shaft press-fitting machine for diaphragm gas meters. Background Technology

[0002] Diaphragm gas meters use an internal mechanical structure to convert linear reciprocating motion into circular motion, which in turn drives a mechanical roller counter. Each reciprocating motion of the diaphragm releases a certain amount of gas, and the roller eventually completes one counting unit, achieving the metering and display effect. Specifically, the diaphragm inside the mechanism transmits its reciprocating oscillation to a rocker arm via a vertical shaft, which then drives a pointer to rotate and measure the gas.

[0003] Vertical shaft assembly is one of the important steps in assembling diaphragm gas meters. During the research and development process, the applicant found that the existing pressing equipment is relatively mature, such as the patent application number "201420397022.1" entitled "Vertical Shaft Pressing Machine for Diaphragm Gas Meter Meter Body". However, it was also found that the existing equipment ignores the structure of the vertical shaft. This is because the position of the mechanism on the production line is usually relatively fixed, while the vertical shaft is different from the assembly part on the mechanism and the connection part with the rocker arm. That is, the structures at both ends of the vertical shaft are different. Therefore, attention should be paid to the orientation of the vertical shaft during assembly. If the orientation is incorrect, it can easily lead to damage to the mechanism or rocker arm. Summary of the Invention

[0004] In view of this, the present invention provides a vertical shaft pressing machine for diaphragm gas meters to solve the problems of component damage or reduced production efficiency caused by vertical shaft orientation issues during the pressing process in the prior art.

[0005] The technical solution is as follows:

[0006] A diaphragm gas meter vertical shaft pressing machine includes a vertical shaft feeding mechanism and a vertical shaft transfer mechanism. The key feature is that a vertical shaft attitude adjustment mechanism is provided between the vertical shaft feeding mechanism and the vertical shaft transfer mechanism. The attitude adjustment mechanism includes a rotary receiving component and a flipping component corresponding to the rotary receiving component. The rotary receiving component is used to receive the vertical shaft fed horizontally by the vertical shaft feeding mechanism, and the flipping component is used to adjust the orientation of the vertical shaft located on the rotary receiving component so that the small end of the vertical shaft faces vertically downward.

[0007] By adopting the above solution, the posture of the vertical shaft is automatically detected and adjusted by setting up a posture adjustment mechanism, thereby ensuring that the large and small ends of the vertical shaft are always aligned when it reaches the transplanting position. This avoids the problem of damage to the pressing parts and greatly improves production efficiency compared to manual selection and placement of the vertical shaft.

[0008] Preferably, the rotary receiving assembly includes a swing cylinder A and a rotary receiving seat connected to the swing head of the swing cylinder A. The swing cylinder A can drive the rotary receiving seat to swing and switch between a horizontal and a vertical position. The rotary receiving seat is provided with a vertical bearing bearing hole. The bottom structure of the vertical bearing bearing hole is stepped and adapts to the small end of the vertical shaft. When the rotary receiving seat is in a horizontal position, the vertical bearing bearing hole faces the side where the vertical shaft feeding mechanism is located. When the rotary receiving seat is in a vertical position, the open end of the vertical bearing bearing hole faces upward. Using the above scheme, the stepped vertical bearing bearing hole receives the vertical shaft. Thus, when the large end of the vertical shaft faces the bottom of the hole, its height will be significantly higher than when the small end faces the bottom of the hole. This allows the external photoelectric detection sensor to accurately determine whether the orientation of the corresponding vertical shaft is correct, further improving the accuracy and efficiency of attitude adjustment.

[0009] Preferably, the vertical shaft feeding mechanism includes a vertical shaft discharge assembly and a horizontal receiving assembly. The vertical shaft discharge assembly includes a vertical shaft hopper with a width adapted to the vertical shaft. The bottom of the hopper has an inclined and movable lifting plate. Below the lifting plate is a discharge cylinder for driving the lifting plate to vibrate. One end of the hopper has a vertically arranged discharge channel located at the lower end of the lifting plate. A vertical shaft baffle is located inside the hopper near the discharge channel, extending along the width of the hopper. The distance between the baffle and the lifting plate at its lower end is between one vertical shaft diameter and the sum of two vertical shaft diameters. This design improves the smoothness of the discharge channel and prevents vertical shaft accumulation.

[0010] Preferably, the horizontal receiving assembly includes a horizontal receiving plate positioned below the discharge channel. The horizontal receiving plate has a receiving groove extending along its width. The horizontal receiving plate is equipped with a receiving cylinder for driving its horizontal sliding. The receiving cylinder pushes the horizontal receiving plate to slide so that the receiving groove is facing or away from the discharge channel, and the length of the receiving groove is less than the length of the vertical shaft. Using this solution, one vertical shaft is received at a time via the receiving groove, enabling rapid reception and transfer of the vertical shaft.

[0011] Preferably, a pushing cylinder is provided on one side of the horizontal receiving plate. The piston rod of the pushing cylinder faces the horizontal receiving plate, and its end is provided with a pushing plate. When the rotating receiving seat is in a horizontal position, it faces the pushing plate. The pushing cylinder can push the vertical shaft located in the receiving groove into the corresponding vertical bearing bearing mounting hole. With the above solution, the pushing cylinder can quickly push the vertical shaft on the horizontal receiving plate into the vertical bearing bearing mounting hole.

[0012] Preferably, the flipping assembly includes a swing cylinder B corresponding to the bearing mounting holes of the vertical bearing, and a flipping position adjustment mechanism for driving the swing cylinder B to move up and down and slide horizontally. The swing cylinder B has a flipping gripper, which can drive the flipping gripper to rotate 180°. Using the flipping position adjustment mechanism to realize the lifting and translation of the swing cylinder B can reduce spatial interference and space occupation, and improve the overall compactness.

[0013] Preferably, the vertical shaft transplanting mechanism includes a vertically arranged transplanting gripper and a transplanting position adjustment mechanism for driving the transplanting gripper to slide horizontally, rise and fall vertically, and rotate horizontally.

[0014] Preferably, the shaft transplanting mechanism includes a frame with a horizontally arranged transplanting guide rail, a transplanting slider that slides with the guide rail, and a rodless cylinder for driving the transplanting slider to slide on the frame.

[0015] The transplanting slider has a vertically downward-facing transplanting lifting cylinder, and the piston rod end of the transplanting lifting cylinder is connected to a swing cylinder C. The transplanting gripper is fixed to the swing head of the swing cylinder C. This design improves the stability of the transplanting gripper's movement, and the swing cylinder C also meets the requirements for subsequent grease application.

[0016] Preferably, a grease application assembly is provided below the support frame. When the transplanting gripper picks up the vertical shaft and moves it horizontally, the vertical shaft can pass through the grease application cavity of the grease application assembly. With the above solution, when the vertical shaft is picked up and moved horizontally by the transplanting gripper, it can be rotated to pass through the grease application cavity, completing the grease application operation. This helps to improve the smoothness of the press-fitting process and further improves the compactness of the overall layout.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The diaphragm gas meter vertical shaft pressing machine provided by this invention enables the adjustment of the posture of the pressing vertical shaft, ensuring that the large and small ends of the vertical shaft always face the same direction, avoiding damage to the pressing parts due to inconsistent orientation. At the same time, it greatly improves production efficiency compared to manual selection of the vertical shaft orientation. The overall layout is compact and has good reliability and accuracy.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] refer to Figures 1 to 11 The diaphragm gas meter vertical shaft pressing machine shown mainly includes a vertical shaft feeding mechanism 100 and a vertical shaft transfer mechanism 200. The key feature of this application is that a vertical shaft attitude adjustment mechanism 300 is provided between the vertical shaft feeding mechanism 100 and the vertical shaft transfer mechanism 200, as shown in the figure. The attitude adjustment mechanism 300 includes a rotary receiving component 310 and a flipping component 320 corresponding to the rotary receiving component 310. The rotary receiving component 310 is used to receive the vertical shaft fed horizontally by the vertical shaft feeding mechanism 100, and the flipping component 320 is used to adjust the orientation of the vertical shaft located on the rotary receiving component 310 so that the small end of the vertical shaft is vertically downward.

[0032] refer to Figures 1 to 5The rotary receiving assembly 310 and the tilting assembly 320 are located on one side of the vertical shaft feeding mechanism 100. The rotary receiving assembly 310 includes a swing cylinder A311 and a rotary receiving seat 312 connected to the swing head of the swing cylinder A311. The swing cylinder A311 can drive the rotary receiving seat 312 to swing and switch between a horizontal position and a vertical position, that is, the swing cylinder A311 can achieve a 90° rotation switch. The rotary receiving seat 312 is provided with a vertical bearing bearing hole 3120, and the bottom structure of the vertical bearing bearing hole 3120 is tiered. The rotating receiving seat 312 is stepped and adapted to the small end of the vertical shaft. When the rotating receiving seat 312 is in a horizontal position, the vertical bearing bearing hole 3120 faces the side where the vertical shaft feeding mechanism 100 is located. When the rotating receiving seat 312 is in a vertical position, the open end of the vertical bearing bearing hole 3120 faces vertically upward. When the large end of the vertical shaft extends into the vertical bearing bearing hole 3120, and when the rotating receiving seat 312 is in a vertical state, its exposed height is higher than when the small end extends in. At this time, the orientation of the vertical shaft can be determined by the photoelectric sensor based on the height of the vertical shaft.

[0033] Specifically, the attitude adjustment mechanism 300 includes a base 330 with at least one vertically arranged column 331. A swing cylinder A311 is fixed to one of the columns 331. The flipping assembly 320 includes swing cylinders B321 corresponding to the bearing bearing holes 3120, and a flipping position adjustment mechanism for driving the swing cylinders B321 to rise, fall, and slide horizontally. The swing cylinders B321 have flipping grippers 322, which can rotate 180°. As shown in the figure, in this embodiment, the rotating receiving seat 312 has two bearing bearing holes 3120, and the column 331... It has two columns, each with a horizontally arranged translation base plate 323. A swing cylinder B321 is horizontally arranged on the corresponding translation base plate 323. The column 331 is equipped with a flip lifting cylinder 324 for driving the translation base plate 323 to rise and fall. At the same time, the translation base plate 323 is equipped with a horizontal sliding flip translation cylinder 325 for driving the swing cylinder B321. The flip gripper 322 is a pneumatic gripper. When the bearing bearing mounting hole 3120 is vertically upward, according to the sensor detection status, if the large and small ends of the vertical shaft are not facing correctly, the vertical shaft can be clamped by the flip assembly 320, raised, flipped, and then lowered back into the bearing bearing mounting hole 3120.

[0034] Key reference Figures 6 to 9The vertical shaft feeding mechanism 100 of this application mainly includes a vertical shaft discharge assembly 110 and a horizontal receiving assembly 120. The vertical shaft discharge assembly 110 includes a vertical shaft hopper 111 with a width adapted to the vertical shaft, as shown in the figure. The vertical shaft hopper 111 is set on the mounting platform 140. The bottom of the vertical shaft hopper 111 has an inclined and movable lifting plate 1110. Below the lifting plate 1110 is a discharge cylinder 112 for driving the lifting plate 1110 to vibrate. One end of the vertical shaft hopper 111 has a vertically arranged discharge passage. The width and length of the discharge channel allow only a single vertical shaft to pass horizontally. The discharge channel is located at the lower end of the lifting plate 1110. A vertical shaft baffle 1111 is provided in the vertical shaft hopper 111 near the discharge channel. The vertical shaft baffle 1111 is set along the width direction of the vertical shaft hopper 111. The distance between its lower end and the lifting plate 1110 is between one vertical shaft diameter and the sum of two vertical shaft diameters. This value takes into account the vibration amplitude of the discharge cylinder 112, that is, to ensure that only one vertical shaft can pass through when the discharge cylinder 112 vibrates.

[0035] The horizontal receiving assembly 120 includes a horizontal receiving plate 121 horizontally disposed below the discharge channel. The horizontal receiving plate 121 has a receiving groove 1210 disposed along its width direction. The horizontal receiving plate 121 is equipped with a receiving cylinder 122 for driving its horizontal sliding. The receiving cylinder 122 pushes the horizontal receiving plate 121 to slide so that the receiving groove 1210 is facing the discharge channel or away from the discharge channel. The length of the receiving groove 1210 is less than the length of the vertical shaft. The horizontal receiving plate 121 and the mounting platform 140 have a sliding fit structure.

[0036] A pusher cylinder 130 is provided on one side of the horizontal receiving plate 121. The piston rod of the pusher cylinder 130 faces the horizontal receiving plate 121, and a pusher plate 131 is provided at its end. The lower end of the pusher plate 131 has a pushing part 132 adapted to the receiving groove 1210. When the rotating receiving seat 312 is in a horizontal position, it faces the pusher plate 131. The pusher cylinder 130 can push the vertical shaft located in the receiving groove 1210 into the corresponding vertical bearing bearing hole 3120.

[0037] refer to Figure 1 , Figure 2 , Figure 10 and Figure 11 The vertical shaft transplanting mechanism 200 in this application mainly includes a frame 220, a vertically arranged transplanting gripper 210, and a transplanting position adjustment mechanism for driving the transplanting gripper 210 to slide horizontally, rise vertically, and rotate horizontally.

[0038] Specifically, the upright frame 220 has a horizontally arranged transplanting guide rail 221, and a transplanting slider 222 that slides with the transplanting guide rail 221. The upright frame 220 is equipped with a rodless cylinder 223 for driving the transplanting slider 222 to slide. The transplanting slider 222 has a vertically downward-facing transplanting lifting cylinder 224. The piston rod end of the transplanting lifting cylinder 224 is connected to a swing cylinder C225. The transplanting gripper 210 is fixed to the swing head of the swing cylinder C225. The transplanting gripper 210 is a thin-type pneumatic gripper, and its gripper plate has a slot 212 that is adapted to the vertical shaft. A magnet 211 is provided on the gripper plate at the position corresponding to the slot to improve the gripping reliability and prevent it from falling off.

[0039] In specific implementation, a grease application component 400 is provided below the upright frame 220. When the transplanting gripper 210 clamps the upright shaft and moves it horizontally, the upright shaft can pass through the grease application cavity of the grease application component 400. The position of the upright shaft can be controlled by the swing cylinder C225 to ensure that it can pass smoothly through the grease application cavity 410.

[0040] refer to Figures 1 to 11 Using the diaphragm gas meter vertical shaft pressing machine of this application, the operator only needs to place the vertical shaft into the vertical shaft hopper 111. The vertical shaft is then lowered from the discharge channel into the receiving groove 1210 on the horizontal receiving plate 121 by the vibration of the discharge cylinder 112. The horizontal receiving plate 121 slides horizontally until the receiving groove 1210 is directly opposite the rotating receiving seat 312 in a horizontal position. At this time, the vertical shaft is directly opposite the bearing mounting hole 3120. Then, the pushing cylinder 310 pushes the vertical shaft into the bearing mounting hole 3120. The swing cylinder A311 rotates until the bearing mounting hole 3120 is vertically upward. The sensor detects the height of the vertical shaft to determine whether the orientation of the large and small ends of the vertical shaft is correct. If the large end is downward, the flipping component 320 is used to clamp the corresponding vertical shaft, flip it, and then return it to its original position. Finally, the vertical shaft transfer mechanism 200 clamps the vertical shaft with the correct orientation, and the grease is applied by the grease application component 400 before pressing.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention. Those skilled in the art, under the guidance of the present invention, can make various similar representations without departing from the spirit and claims of the present invention, and such modifications all fall within the protection scope of the present invention.
