Description

Technical Field

[0002] In modern industrial production, pressure gauges, as an important pressure measuring instrument, are widely used in various industrial equipment and systems. Pressure gauge joints are the connecting parts between the pressure gauge and the measured equipment or pipelines. Their processing quality directly affects the measurement accuracy of the pressure gauge and the sealing and reliability of the connection. In the processing of pressure gauge joints, grinding is a key process. The purpose of grinding is to remove burrs, oxide scales and other impurities on the surface of the joints, improve the smoothness of the joint surface, and ensure the good fit between the joints and other components.

[0003] Application No. CN202120250549.1 discloses a joint trimming machine for a pressure gauge, which relates to the field of joint grinding technology, and aims to solve the problem of deformation of the pressure gauge joint due to unstable hands.

The tooling fixture includes a base, two vertical plates and a fixed block clamped on the support plate.

An annular groove for embedding the step is provided on the outer side of the edge of the fixed block, and a threaded hole is provided on the top surface of the fixed block. The pressure gauge joint can be firmly connected to the fixed block through the threaded hole, thereby avoiding deformation of the pressure gauge joint during the grinding process, thereby reducing the defective rate of the pressure gauge, which is beneficial to improving the quality of the pressure gauge.

[0027] Among them, scale values are provided on both sides of the lifting frame 2. A motor A203 is fixedly installed at the upper left side of the lifting frame 2, and the rotating shaft of the motor A203 is located inside the top end of the lifting frame 2.

[0028] Among them, the two opposite sliders 204 are symmetrically designed, and a through threaded hole is opened on the side of each opposite slider 204. The threaded holes of the two opposite sliders 204 are symmetrically designed. The threads on both sides of the rotating shaft of the motor A203 are designed in the reverse direction, and the rotating shaft of the motor A203 is respectively located in the threaded holes of the two opposite sliders 204.

[0029] Among them, a motor B301 is fixedly installed at the rear end position of the delivery rack 3, the rotating shaft of motor B301 is located at the internal position of the delivery rack 3, and the rotating shaft of motor B301 is provided with a thread, a threaded hole is opened at the front end position of the delivery block 302, the rotating shaft of motor B301 is located in the threaded hole of the delivery block 302, an adjusting rack 4 is fixedly connected to the bottom position of the surrounding rack 305, a motor D401 is fixedly installed at the inner side position of the adjusting rack 4, the rotating shaft of motor D401 is provided with a thread, and the rotating shaft of motor D401 is located in the middle position inside the adjusting rack 4, an adjusting slider 402 is slidably connected at the lower position inside the adjusting rack 4, a threaded hole is opened in the middle position of the adjusting slider 402, the rotating shaft of motor D401 is located in the threaded hole of the adjusting slider 402, a grinding rack 403 is fixedly installed at the middle position of the bottom of the adjusting slider 402, and a grinder 404 is fixedly installed at the lower position of the grinding rack 403.

[0030] Among them, the bottom positions of the two lifting cylinders 201 are installed on the left and right sides of the rear end of the top of the support seat 1, the support seat 1 is located below the lifting frame 2, and a base 101 is installed at the bottom of the support seat 1. The base 101 is composed of support legs and universal wheels. A collecting rack 102 is fixedly installed in the middle position of the top front end of the support seat 1. The middle position of the collecting rack 102 is a conical funnel design. A collecting box 103 is placed at the front middle position of the top of the support seat 1. The collecting box 103 is located below the collecting rack 102. A clamp 104 is fixedly installed in the middle upper position of the collecting rack 102 through a rod body, and the internal clamping joint parts 105 of the clamp 104 are.

[0031] When the delivery block 302 slides to the frontmost position inside the delivery rack 3 , the two half-toothed ring racks 304 are located directly above the clamp 104 .

[0032] When using: The support base 1 is transferred to a suitable position by the universal wheels of the base 101 , and then the legs of the base 101 are adjusted so that the legs of the base 101 contact the ground to provide support to the support base 1 .

[0033] When the pressure gauge joint needs to be fixed, the joint part 105 to be processed is clamped inside the fixture 104 to ensure that the joint part 105 is firmly fixed.

[0034] According to the height position of the joint part 105 to be polished, the sliding between the lifting frame 2 and the lifting cylinder 201 is adjusted. After the height position of the lifting frame 2 is determined, the two positioning bolts 202 are tightened respectively so that the inner sides of the two positioning bolts 202 are tightly attached to the wall position of the lifting frame 2 to limit the height of the lifting frame 2; Start the motor B301, and the shaft thread of the motor B301 cooperates with the threaded hole of the delivery block 302, so that the delivery block 302 slides forward on the inner side of the delivery frame 3 until the delivery block 302 fits the inner front end of the delivery frame 3, ensuring that the two half-toothed ring frames 304 are located directly above the clamp 104. At this time, start the motor D401, and the shaft thread of the motor D401 cooperates with the threaded hole of the adjusting slider 402, so that the adjusting slider 402 slides in the internal position of the adjusting frame 4, and adjusts the distance between the grinder 404 and the joint part 105, until the required grinding area of ​​the joint part 105 contacts the grinding position of the grinder 404, and the joint part 105 is ground by the grinder 404.

[0035] When circular grinding is required, the motor C307 is started. When the shaft of the motor C307 rotates, the gear part 308 is driven to rotate. Since the gear part 308 is meshed with the half-toothed ring frame 304, the surrounding frame 305 makes a circular motion in the T-slots of the two half-toothed ring frames 304. The circular motion of the surrounding frame 305 drives the grinding frame 403 and the grinder 404 set on the adjusting frame 4 connected to the bottom thereof to make a circular motion around the joint part 105, completing the process link of the circular grinding. The debris and waste generated during the grinding process fall into the collection box 103 through the conical funnel design of the collection frame 102.

[0036] Start the motor A203. Since the threads on both sides of the rotating shaft of the motor A203 are designed in reverse, when the motor A203 rotates, it will drive the two opposing sliders 204 to slide on the left and right sides of the top of the lifting frame 2, thereby adjusting the distance between the two delivery frames 3. When the distance between the two delivery frames 3 increases, the two half-toothed ring frames 304 are disengaged. At this time, the T-shaped slider 306 can be removed from the connection of the half-toothed ring frames 304, and the two half-toothed ring frames 304 can be maintained in a targeted manner, and the entire adjustment frame 4 can be disassembled and maintained.

[0037] The shaft thread of motor B301 is reversed in conjunction with the threaded hole of delivery block 302, so that delivery block 302 slides backward on the inner side of delivery rack 3 until delivery block 302 fits against the inner rear end of delivery rack 3. At this time, the entirety of adjustment rack 4 will not be located above fixture 104, and will not be obstructed when installing and removing joint parts 105 in fixture 104.

[0038] The above are only specific implementations of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and the protection scope of the present disclosure shall be based on the protection scope of the claims.
