Description

Technical Field

[0001] This application relates to the field of assembling equipment, and more particularly to a pressure gauge fixing device. Background Technology

[0002] When assembling a pressure gauge into the housing of a water pump controller, current technology generally involves manual operation. A wrench is used to engage the hexagonal locking block on the pressure gauge, causing it to rotate. However, the torque required for the pressure gauge to rotate to the housing of the water pump controller is not accurately controlled manually, sometimes damaging the pressure gauge. Manual operation is inefficient, and the installation space in the housing of the water pump controller is small. The wrench can also impact the housing when rotating, causing damage to the housing. Summary of the Invention

[0003] In order to reduce the possibility of damage to the water pump controller housing and pressure gauge, improve the working efficiency of the water pump controller housing and pressure gauge device, and reduce production costs, this application provides a pressure gauge fixing device.

[0004] The pressure gauge fixing device provided in this application adopts the following technical solution:

[0005] A pressure gauge fixing device includes a frame, a mounting base, a fixing drive cylinder, a fixing block, a wrench, a first drive cylinder, and a tightening motor. The mounting base is connected to the frame, and a protrusion is connected to the upper end of the mounting base for fitting against the inner wall of a water pump controller housing. The fixing block is connected to the frame and abuts against the side of the water pump controller housing away from the mounting base. The fixing drive cylinder is connected to the frame and drives the fixing block to slide. The wrench is connected to the frame, and one end of the wrench has a slot for a hexagonal locking block of the pressure gauge to be inserted. The slot wall fits against two parallel sides of the hexagonal locking block of the pressure gauge. The first drive cylinder is connected to the frame and drives the wrench to slide. The sliding direction of the wrench is perpendicular to the axis of the pressure gauge. The tightening motor is connected to the frame and drives the wrench to rotate. The rotation axis of the wrench coincides with the axis of the pressure gauge.

[0006] By adopting the above technical solution, the protrusion fits into the inner wall of the water pump controller housing, and the fixed drive cylinder drives the fixed block to abut against the surface of the water pump controller housing away from the mounting base, thereby achieving relative fixation between the water pump controller housing and the mounting base. This reduces the possibility of misalignment during the assembly of the water pump controller housing and the pressure gauge. The first drive cylinder drives the hexagonal locking block of the pressure gauge to insert into or disengage from the slot, and the tightening motor drives the wrench to rotate, achieving precise torque control. This reduces the possibility of pressure gauge damage due to human factors and improves assembly quality and efficiency.

[0007] Preferably, it also includes a turntable and a rotary motor. The turntable is rotatably connected to the frame, and the rotation axis of the turntable is vertical. The rotary motor is connected to the frame and is used to drive the turntable to rotate. Several mounting seats are provided, and the mounting seats are evenly distributed around the rotation axis of the turntable. The number of fixed blocks and fixed drive cylinders is the same as the number of mounting seats and corresponds one-to-one.

[0008] By adopting the above technical solution and setting up multiple mounting bases, the water pump controller housing on other mounting bases can be placed and the pressure gauge can be initially fixed while the pressure gauge is being tightened with a wrench, thus improving work efficiency.

[0009] Preferably, the device further includes a positioning drive cylinder, a positioning block, and a positioning seat. The number of positioning seats is the same as the number of mounting seats and corresponds one-to-one. The positioning seat is connected to the turntable and has a positioning groove. The positioning block is slidably connected to the frame and is used to embed into the positioning groove. The positioning drive cylinder is connected to the frame and is used to drive the positioning block to slide.

[0010] By adopting the above technical solution, the positioning drive cylinder drives the positioning block to slide, and the positioning block is embedded in the positioning groove, so that the pressure gauge is located directly below the wrench, which facilitates the wrench to assemble the pressure gauge. In addition, the relative fixation of the turntable and the frame reduces the possibility of the turntable deflecting when the wrench tightens the pressure gauge, thereby improving the reliability and safety of the device.

[0011] Preferably, it further includes a sliding seat, a first reset member, and a clamping block. The sliding seat is connected to the turntable. The number of the first reset member and the clamping block is the same as the number of mounting seats and corresponds one-to-one. The clamping block is slidably connected to the sliding seat. The sliding direction of the clamping block is vertical. The lower end of the clamping block is provided with a clamping groove. The clamping groove is used for the hexagonal locking block of the pressure gauge to be inserted. The side wall of the clamping groove fits against the outer wall of the hexagonal locking block of the pressure gauge. The first reset member is connected between the clamping block and the sliding seat. The first reset member makes the clamping block tend to press against the outer wall of the hexagonal locking block of the pressure gauge.

[0012] By adopting the above technical solution, the first reset component drives the clamping block to abut against the hexagonal locking block of the pressure gauge, so that when the turntable rotates, the two parallel sides of the hexagonal locking block of the pressure gauge remain vertical, which makes it easy for the wrench to move down and so that the hexagonal locking block of the pressure gauge is embedded in the slot, thereby improving the reliability and consistency of the device.

[0013] Preferably, the device further includes a locking component. The upper end of the turntable has a first sliding groove extending horizontally. The end of the first sliding groove near the mounting base has a second sliding groove penetrating the turntable vertically. The lower end of the sliding base is slidably embedded in the first and second sliding grooves. The locking component includes a locking block, a pushing block, and a second reset member. The number of locking blocks, pushing blocks, and second reset members is the same as the number of mounting bases and corresponds one-to-one. The locking block is slidably connected to the turntable, and its sliding direction is horizontal. The sliding base has a locking groove for the locking block to be embedded in. The second reset member is connected between the locking block and the turntable, and it causes the locking block to tend to embed in the locking groove. The pushing block is slidably connected to the turntable, and its sliding direction is vertical. The lower end of the pushing block has a first chamfer located on the side of the pushing block away from the sliding base, and the first chamfer is used to abut against the locking block. The upper end of the pushing block has a second chamfer located on the side of the pushing block away from the sliding base, and the second chamfer is used to abut against the positioning block.

[0014] By adopting the above technical solution, when the mounting base rotates to the position, it pulls the sliding base upward along the second slide groove. Then, it moves the sliding base away from the mounting base along the first slide groove, making it easier for the wrench to engage the hexagonal locking block of the pressure gauge. When placed, the locking block is embedded in the locking groove under the action of the elastic force of the second reset member, realizing the relative fixation of the sliding base and the turntable. This reduces the risk of the sliding base shifting during the initial fixation of the pressure gauge, which would affect the limiting effect of the clamping block and improve the reliability of the device. The positioning block slides against the second chamfer, and the first chamfer abuts against the locking block, driving the locking block to overcome the elastic force of the second reset member and disengage from the locking groove, releasing the relative fixation of the sliding base and the turntable, making it easier to pull the sliding base away from the mounting base.

[0015] Preferably, it further includes an ejector block and a third reset member. The ejector block is slidably connected to the frame. The ejector block slides vertically. The upper end of the ejector block is provided with a rounded corner, which is used to abut against the lower end of the sliding seat. The third reset member is connected between the ejector block and the frame. The third reset member makes the lower end of the sliding seat tend to correspond to the first sliding groove.

[0016] By adopting the above technical solution, the sliding seat rotates and abuts against the rounded corner, pushing and pushing the ejector block downward against the elastic force of the third reset member. When the locking block releases the lock on the sliding seat, the ejector block pushes the sliding seat upward under the action of the elastic force of the third reset member, locking the lower end of the sliding seat to be flush with the bottom of the first slide groove, making it easier to pull the sliding seat away from the mounting seat.

[0017] Preferably, it further includes a rotating base, a fixed gear, and a rotating gear. The rotating base is rotatably connected to the frame, and the rotation axis of the rotating base coincides with the axis of the pressure gauge. The fixed gear is connected to the frame, and the rotating gear is rotatably connected to the rotating base. The rotating gear meshes with the fixed gear. The tightening motor is connected to the rotating base and is used to drive the rotating gear to rotate. The first drive cylinder is connected to the rotating base, and the wrench is slidably connected to the rotating base.

[0018] By adopting the above technical solution, the rotating connection between the rotating seat and the frame, as well as its alignment with the pressure gauge axis, ensures that the wrench can accurately align with the hexagonal locking block of the pressure gauge during rotation, reducing the possibility of pressure gauge damage due to positional deviation. The tightening motor drives the rotating gear to rotate, and the rotating gear meshes with the fixed gear, enabling the rotating seat to rotate along the pressure gauge axis, thus improving the stability and accuracy of the speed.

[0019] Preferably, the frame is connected to a guide plate, and the rotating seat includes a front plate, a rear plate, a connecting block, and a limiting seat. The front plate and the rear plate are located on both sides of the guide plate along the thickness direction of the guide plate. The guide plate is provided with an arc-shaped groove centered on the axis of the fixed gear. The connecting block is slidably embedded in the arc-shaped groove, and the two ends of the connecting block are respectively connected to the front plate and the rear plate. The limiting seat is connected to the front plate and is provided with a connecting groove. The wrench is slidably embedded in the connecting groove, and the side wall of the wrench is in contact with the groove wall of the connecting groove.

[0020] By adopting the above technical solution, the guide plate is provided with an arc-shaped groove, and the connecting block is slidably embedded in the arc-shaped groove, which guides the rotation of the rotating seat and improves the stability and reliability of the device.

[0021] Preferably, the rotating seat further includes rollers, which are divided into two groups. The two groups of rollers are rotatably connected to the front plate and the rear plate on the side surface near the guide plate, respectively, and the outer wall of the rollers is in contact with the guide plate.

[0022] By adopting the above technical solution, the rotating seat is equipped with rollers, which transforms the sliding friction between the rotating seat and the guide plate into rolling friction, reduces the friction between the rotating seat and the guide plate, reduces the possibility of the rotating seat getting stuck due to excessive friction, and improves the stability of the device.

[0023] Preferably, it further includes a limit drive cylinder and a limit block, the limit block being slidably connected to the limit seat, the sliding direction of the limit block being perpendicular to the sliding direction of the wrench, the wrench having a limit groove for the limit block to be inserted into, and the two sidewalls of the limit block along the sliding direction of the wrench being in contact with the groove wall of the limit groove.

[0024] By adopting the above technical solution, the limit drive cylinder drives the limit block to slide into the limit groove, reducing the possibility of the wrench deviating or tilting during rotation and improving the reliability of the device.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The protrusion fits against the inner wall of the water pump controller housing. The fixed drive cylinder drives the fixed block to abut against the surface of the water pump controller housing away from the mounting base, thereby fixing the water pump controller housing and the mounting base relatively. This reduces the possibility of misalignment during the assembly of the water pump controller housing and the pressure gauge. The first drive cylinder drives the hexagonal locking block of the pressure gauge to insert into or disengage from the slot. The tightening motor drives the wrench to rotate, achieving precise torque control. This reduces the possibility of pressure gauge damage due to human factors and improves assembly quality and efficiency.

[0027] 2. The first reset component drives the clamping block to abut against the hexagonal locking block of the pressure gauge, so that when the turntable rotates, the two parallel sides of the hexagonal locking block of the pressure gauge remain vertical, which makes it easier for the wrench to move down and so that the hexagonal locking block of the pressure gauge is embedded in the slot, thereby improving the reliability and consistency of the device.

[0028] 3. When the mounting base is rotated into position, pull the sliding base upward along the second slide groove. Then, move the sliding base away from the mounting base along the first slide groove to facilitate the wrench engaging the hexagonal locking block of the pressure gauge. During placement, the locking block is embedded in the locking groove under the action of the elastic force of the second reset member, realizing the relative fixation of the sliding base and the turntable. This reduces the risk of the sliding base shifting during the initial fixation of the pressure gauge, which could affect the limiting effect of the clamping block and improve the reliability of the device. The positioning block slides against the second chamfer, and the first chamfer abuts against the locking block, driving the locking block to overcome the elastic force of the second reset member and disengage from the locking groove, releasing the relative fixation of the sliding base and the turntable, making it easier to pull the sliding base away from the mounting base.

[0054] The implementation principle of the pressure gauge fixing device in this application embodiment is as follows: the water pump controller housing is placed on the upper end of the mounting base 23, and the sliding seat 261 is pulled so that the lower end of the sliding seat 261 is embedded in the second sliding groove 222 on the side away from the guide plate 12. Under the action of the elastic force of the second reset member 273, the locking block 271 is embedded in the locking groove 2611, thereby realizing the relative fixation of the sliding seat 261 and the turntable 22 in the vertical direction.

[0055] The pressure gauge is threaded into the connection hole of the water pump controller housing. The first reset component 262 drives the clamping block 263 to move downward, and the groove wall of the clamping groove 2631 presses against the outer wall of the hexagonal locking block of the pressure gauge, so that the two parallel sides of the hexagonal locking block of the pressure gauge are in a vertical state. The piston rod of the fixed drive cylinder 241 retracts, driving the fixed block 242 to rotate and move downward to abut against the upper end of the water pump controller housing.

[0056] The rotary motor 21 operates, driving the turntable 22 to rotate, which in turn drives the mounting base 23 to rotate, and consequently, the water pump controller housing and pressure gauge to rotate. The piston rod of the positioning drive cylinder 251 extends, pushing the positioning block 252 to slide, causing it to embed into the positioning groove 2531, thus fixing the turntable 22 and the base 13 relatively. The positioning block 252 abuts against the second chamfer 2722, pushing the pushing block 272 downwards. The first chamfer 2721 abuts against the third chamfer 2713, causing the locking block 271 to slide away from the sliding seat 261, allowing the locking block 271 to pass through the locking groove 2611, releasing the relative fixation between the sliding seat 261 and the turntable 22. The third reset component 112 drives the ejector block 111 to extend out of the sixth slide groove 134. The ejector block 111 pushes the lower end of the sliding seat 261 flush with the bottom of the first slide groove 221, facilitating the operator to pull the sliding seat 261 into the first slide groove 221.

[0057] The piston rod of the first drive cylinder 32 extends, causing the wrench 31 to slide closer to the pressure gauge, so that the hexagonal locking block of the pressure gauge is embedded in the locking groove 311, and the two parallel sides of the hexagonal locking block of the pressure gauge are in contact with the groove wall of the locking groove 311. The piston rod of the limit drive cylinder 371 extends, pushing the limit block 372 through the limit groove 312 and then embedded in the fixed groove 3443. The tightening motor 33 works, driving the rotating gear 36 to rotate. The rotating gear 36 meshes with the fixed gear 35, driving the rear plate 342 to rotate along the axis of the fixed gear 35, causing the connecting hole to slide into the arc groove 121, driving the front plate 341 to rotate, driving the limit seat 344 to rotate, driving the wrench 31 to rotate, and rotating the pressure gauge by a certain angle. The piston rod of the first drive cylinder 32 retracts, causing the wrench 31 to slide away from the pressure gauge, thus causing the hexagonal locking block of the pressure gauge to spring into its groove 311. The tightening motor 33 reverses, driving the rotating gear 36 to rotate, which in turn rotates the wrench 31 to the other side. The piston rod of the first drive cylinder 32 extends, causing the wrench 31 to slide closer to the pressure gauge, causing the hexagonal locking block of the pressure gauge to embed into the groove 311, making the two parallel sides of the hexagonal locking block fit against the groove wall of the groove 311. The tightening motor 33 operates, driving the rotating gear 36 to rotate, which in turn drives the wrench 31 to rotate, rotating the pressure gauge by a certain angle. This process is repeated multiple times until the pressure gauge is installed. The piston rod of the limit drive cylinder 371 retracts, causing the limit block 372 to disengage from the limit groove 312. The piston rod of the first drive cylinder 32 retracts, causing the wrench 31 to slide away from the pressure gauge. The piston rod of the positioning drive cylinder 251 retracts, causing the positioning block 252 to disengage from the positioning groove 2531, releasing the relative fixation between the turntable 22 and the base 13.
