Description

Technical Field

[0001] This utility model relates to the field of pressure gauge manufacturing technology, and in particular to an assembly tooling applicable to multiple types of pressure gauges. Background Technology

[0002] A pressure gauge is an instrument that uses an elastic element as a sensing element to measure and indicate pressures higher than the ambient pressure. It is widely used and can be found in almost all industrial processes and scientific research fields. The pressure gauge housing consists of a base and a top cover. During installation and assembly, the top cover and the base need to be screwed together and fixed.

[0003] Existing technologies, such as Chinese Patent Publication No. CN220161738U, disclose an assembly device for manufacturing diaphragm pressure gauges. The device includes a base with four supporting legs evenly distributed around its perimeter. A clamping mechanism is fixedly mounted on the top surface of the base, and an assembly mechanism is fixedly mounted on the top surface of the clamping mechanism. The clamping mechanism includes a clamping section and a power section, with the side of the power section fixedly connected to the side of the clamping section. The power section includes a motor A, with its right side fixedly connected to the left side of the base. This assembly device for manufacturing diaphragm pressure gauges, through the assembly mechanism and the coordinated operation of the motor B and the device block, allows the gauge cover, clamped by the clamping block, to rotate. This enables quick installation with the gauge body and allows for adjustable rotation to different angles, making operation simple and fast.

[0004] To address the issue of the inability to quickly and automatically assemble multiple types of pressure gauges, the current assembly and loading / unloading of pressure gauge housings mainly rely on manual operation, which is time-consuming, labor-intensive, and inefficient. Especially when dealing with multiple types of pressure gauges, it may be necessary to change the fixtures. Furthermore, it is not possible to ensure that the tightening force of each pressure gauge is the same, which can easily lead to problems such as the chassis not being tightened properly or being over-tightened. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where pressure gauge assembly cannot be conveniently and automatically assembled for multiple types of pressure gauges, and to propose an assembly fixture applicable to multiple types of pressure gauges.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a multi-type pressure gauge assembly fixture, including a base, legs, and a clamping device. The legs are fixedly connected to the surface of the base, and the number of legs is four sets arranged symmetrically. The clamping device is disposed on the surface of the base and includes a cavity. The cavity is opened inside the base, and a motor is fixedly installed on the surface of the cavity. A turntable is fixedly connected to the output end of the motor. A threaded groove is opened on the surface of the turntable. A placement groove is opened on the surface of the base, and a sliding groove is opened on the surface of the placement groove. A slider is slidably connected to the surface of the sliding groove. The end of the slider near the turntable is slidably connected to the surface of the threaded groove, and a clamping plate is fixedly connected to the end of the slider away from the turntable.

[0007] Furthermore, the surface of the base is provided with a second sliding groove, and a second slider is slidably connected to the surface of the second sliding groove. The end of the second slider near the turntable is slidably connected to the surface of the threaded groove, and the end of the second slider away from the turntable is fixedly connected to a telescopic rod. The other end of the telescopic rod is fixedly connected to a second clamping plate.

[0008] Furthermore, a spring is sleeved and connected to the surface of the telescopic rod, one end of the spring is fixedly connected to the surface of the second slider, and the other end of the spring is fixedly connected to the surface of the second clamping plate.

[0009] Furthermore, the number of the first slide groove, the first slider, the first clamping plate, the second slide groove, the second slider, the telescopic rod, the second clamping plate, and the spring are all four sets and are distributed in a circle. The surface of the first clamping plate is provided with anti-slip texture.

[0010] Furthermore, the surface of the base is provided with an assembly device, the assembly device including an L-shaped plate, the L-shaped plate being fixedly connected to the surface of the base, the surface of the L-shaped plate having a receiving groove, the inner wall of the L-shaped plate being rotatably connected to a screw, the screw being disposed inside the receiving groove, the surface of the L-shaped plate being fixedly mounted with a second motor, the output end of the second motor being fixedly connected to one end of the screw, the surface of the screw being threadedly connected to a movable platform, the movable platform being slidably connected to the surface of the receiving groove.

[0011] Furthermore, a cylinder is fixedly installed on the surface of the active platform, a mounting plate is fixedly connected to the driving end of the cylinder, a motor is fixedly installed on the surface of the mounting plate, a placement plate is fixedly connected to the output end of the motor, a rotating rod is fixedly connected to the surface of the placement plate, and an adsorption plate is fixedly connected to the surface of the rotating rod.

[0012] Furthermore, an air pump is fixedly installed on the surface of the placement plate, and a hose is fixedly connected to the surface of the air pump. The hose passes through the surface of the placement plate and is connected to the surface of the adsorption plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a clamping device, when it is necessary to tighten and assemble the pressure gauge cover and chassis, the chassis is first placed in the placement groove using the assembly device, and then the cover is placed on top of the chassis. Subsequently, the motor is started to make the turntable rotate. Under the action of the threaded groove, the four sets of sliders move towards the chassis along the first slide groove, and at the same time, the four sets of sliders move towards the cover along the second slide groove. Thus, the four sets of clamping plates clamp the chassis and the four sets of clamping plates clamp the cover. The anti-slip texture allows the clamping plate to strongly fix the chassis, while the telescopic rod and spring allow the clamping plate to only weakly fix the cover. This makes it easy for the chassis to remain stationary while the cover can rotate during subsequent tightening. The adjustable clamping method can be used for multiple types of pressure gauges without changing the clamps. By setting a clamping device, the pressure gauge chassis is strongly fixed while the cover is weakly fixed, which is convenient for alignment and does not affect subsequent tightening operations. The adjustable clamps are suitable for multiple types of pressure gauges, which effectively improves the applicability of the equipment.

[0015] 2. In this utility model, by setting up an assembly device, starting motor two causes the screw to rotate, thereby causing the movable table to slide along the receiving groove for loading and unloading the pressure gauge chassis and top cover. When it reaches above the workpiece, the cylinder is activated to make the mounting plate face downwards, thereby causing the adsorption plate to adhere tightly to the upper surface of the workpiece. Then, the vacuum pump is activated to extract the air inside the adsorption plate through the hose, using negative pressure to adsorb the workpiece for easy loading and unloading. After loading is completed, the adsorption plate moves to the top of the placement groove and adsorbs the top cover again. Starting motor three causes the placement plate to rotate, thereby driving the rotating rod to rotate, causing the adsorption plate to drive the top cover to rotate. Since clamp two is weakly fixed to the top cover, it will not affect the rotation of the top cover. Moreover, due to the use of negative pressure adsorption, if the adsorption plate continues to rotate when the top cover and chassis are sufficiently tightened, the adsorption will fail, avoiding over-tightening of the top cover and chassis and causing damage. By setting up an assembly device, it is convenient to load, unload, and tighten the pressure gauge's top cover and chassis, saving manpower and time costs, thus effectively improving the convenience of the equipment.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a multi-type pressure gauge applicable assembly tooling, including a base 1, legs 2 and clamping device 3. The legs 2 are fixedly connected to the surface of the base 1. The number of legs 2 is four sets and they are symmetrically arranged. The clamping device 3 is disposed on the surface of the base 1.

[0024] The specific setup and function of the clamping device 3 and the assembly device 4 will be explained in detail below.

[0025] In this embodiment: the clamping device 3 includes a cavity 301, which is formed inside the base 1. A motor 302 is fixedly installed on the surface of the cavity 301. A turntable 303 is fixedly connected to the output end of the motor 302. A threaded groove 304 is formed on the surface of the turntable 303. A placement groove 305 is formed on the surface of the base 1. A sliding groove 306 is formed on the surface of the placement groove 305. A slider 307 is slidably connected to the surface of the sliding groove 306. One end of the slider 307 near the turntable 303 is slidably connected to the surface of the threaded groove 304. A clamping plate 308 is fixedly connected to the end of the slider 307 away from the turntable 303.

[0026] The effect achieved by the above components is as follows: First, the chassis is placed into the placement slot 305 using the assembly device 4, then the top cover is placed on top of the chassis, and then the motor 302 is started to make the turntable 303 rotate. Under the action of the threaded groove 304, the slider 307 moves closer to the chassis along the slide groove 306, so that the clamping plate 308 clamps the chassis. The cavity 301 is provided to house the motor 302 and the turntable 303.

[0027] Specifically, the surface of the base 1 is provided with a second sliding groove 309, and a second slider 310 is slidably connected to the surface of the second sliding groove 309. The end of the second slider 310 near the turntable 303 is slidably connected to the surface of the threaded groove 304. The end of the second slider 310 away from the turntable 303 is fixedly connected to a telescopic rod 311, and the other end of the telescopic rod 311 is fixedly connected to a second clamping plate 312.

[0028] The effect achieved by the above components is as follows: the turntable 303 rotates, and under the action of the threaded groove 304, the slider 310 moves closer to the upper cover along the groove 309, thereby causing the clamping plate 312 to clamp the upper cover.

[0029] Specifically, a spring 313 is sleeved and connected to the surface of the telescopic rod 311. One end of the spring 313 is fixedly connected to the surface of the second slider 310, and the other end of the spring 313 is fixedly connected to the surface of the second clamping plate 312.

[0030] The effect achieved by the above components is as follows: the spring 313 is set to cooperate with the telescopic rod 311 so that the clamping plate 312 only weakly fixes the upper cover. When the tightening operation is performed later, the upper cover can still rotate under clamping.

[0031] Specifically, there are four sets of slide groove 306, slider 307, clamping plate 308, slide groove 309, slider 310, telescopic rod 311, clamping plate 312 and spring 313, which are distributed in a circle. The surface of clamping plate 308 is provided with anti-slip texture 314.

[0032] The effects achieved by the above components are as follows: the four sets of adjustable clamping plates 308 and 312 are for stable clamping of the chassis and the top cover, and can be used for various types of pressure gauges without the need to change the clamps. The anti-slip texture 314 is to increase friction to facilitate the clamping plate 308 to firmly fix the chassis.

[0033] Specifically, the surface of the base 1 is provided with an assembly device 4, which includes an L-shaped plate 401. The L-shaped plate 401 is fixedly connected to the surface of the base 1. The surface of the L-shaped plate 401 is provided with a receiving groove 402. The inner wall of the L-shaped plate 401 is rotatably connected with a screw 403. The screw 403 is located inside the receiving groove 402. A second motor 404 is fixedly installed on the surface of the L-shaped plate 401. The output end of the second motor 404 is fixedly connected to one end of the screw 403. The surface of the screw 403 is threadedly connected with a movable table 405. The movable table 405 is slidably connected to the surface of the receiving groove 402.

[0034] The effect achieved by the above components is as follows: starting motor 404 causes screw 403 to rotate, which in turn causes movable table 405 to slide along receiving groove 402. Receiving groove 402 is provided to place screw 403 and to make movable table 405 move only horizontally and not rotate with screw 403.

[0035] Specifically, a cylinder 406 is fixedly installed on the surface of the activity table 405. A mounting plate 407 is fixedly connected to the drive end of the cylinder 406. A motor 408 is fixedly installed on the surface of the mounting plate 407. A placement plate 409 is fixedly connected to the output end of the motor 408. A rotating rod 410 is fixedly connected to the surface of the placement plate 409. An adsorption plate 411 is fixedly connected to the surface of the rotating rod 410.

[0036] The effects achieved by the above components are as follows: starting the cylinder 406 causes the mounting plate 407 to move up and down, which in turn causes the adsorption plate 411 to move up and down, adsorbing the workpiece for easy loading and unloading; starting the motor 408 causes the placement plate 409 to rotate, which in turn causes the rotating rod 410 to drive the adsorption plate 411 to rotate, making it easier to tighten the chassis and the top cover.

[0037] Specifically, an air pump 412 is fixedly installed on the surface of the placement plate 409, and a hose 413 is fixedly connected to the surface of the air pump 412. The hose 413 passes through the surface of the placement plate 409 and is connected to the surface of the adsorption plate 411.

[0038] The effect achieved by the above components is as follows: when the adsorption plate 411 is in close contact with the workpiece, the air pump 412 is started to extract the air inside the adsorption plate 411 through the hose 413, and the workpiece is adsorbed by negative pressure to facilitate loading, unloading and tightening operations.

[0039] Working principle: By setting up clamping device 3, when it is necessary to tighten and assemble the pressure gauge cover and the chassis, firstly, the chassis is placed into the placement groove 305 using assembly device 4, and then the cover is placed on top of the chassis. Subsequently, motor 302 is started to rotate turntable 303. Under the action of threaded groove 304, four sets of sliders 307 move closer to the chassis along slide groove 306, while four sets of sliders 310 move closer to the cover along slide groove 309. This causes four sets of clamping plates 308 to clamp the chassis and four sets of clamping plates 312 to clamp the cover, with anti-slip features. The clamp 314 provides strong fixation to the chassis, while the telescopic rod 311 and spring 313 provide only weak fixation to the top cover via the clamp 312. This allows the chassis to remain stationary while the top cover can rotate during subsequent tightening. The adjustable clamping method is suitable for various types of pressure gauges without requiring clamp replacement. By using the clamping device 3, the pressure gauge chassis is strongly fixed while the top cover is weakly fixed, facilitating alignment without affecting subsequent tightening operations. Furthermore, the adjustable clamps are suitable for various types of pressure gauges, effectively improving the equipment's applicability. The assembly device 4 is set up, and the motor 404 is started to rotate the screw 403, which in turn causes the movable table 405 to slide along the receiving groove 402 for loading and unloading the pressure gauge base and the top cover. When it reaches above the workpiece, the cylinder 406 is started to lower the mounting plate 407, which in turn causes the adsorption plate 411 to adhere tightly to the upper surface of the workpiece. Then, the vacuum pump 412 is started to extract the air inside the adsorption plate 411 through the hose 413, using negative pressure to adsorb the workpiece for easy loading and unloading. After loading is completed, the adsorption plate 411 moves to directly above the placement groove 305 and adsorbs the top cover again. The starting motor 408 causes the placement plate 409 to rotate, which in turn drives the rotating rod 410 to rotate, causing the adsorption plate 411 to rotate the upper cover. Since the clamping plate 312 provides a weak fixation to the upper cover, it does not affect the rotation of the upper cover. Furthermore, due to the use of negative pressure adsorption, if the adsorption plate 411 continues to rotate when the upper cover and the chassis are sufficiently tightened, the adsorption will fail, thus avoiding over-tightening the upper cover and chassis and causing damage. By setting up the assembly device 4, it is convenient to load, unload, and tighten the upper cover and chassis of the pressure gauge, saving manpower and time costs, and effectively improving the convenience of the equipment.
