Description

Technical Field

[0003] The grinding machine is used to grind the outer cylindrical surface, inner cylindrical surface and end surface of the workpiece, so as to achieve the surface roughness of the workpiece to meet the use requirements of the workpiece. The grinding wheel is installed on the driving shaft of the grinding machine, and the workpiece is installed on the movable worktable of the grinding machine to realize the rotation and movement of the workpiece. The grinding wheel grinds the surface of the workpiece during relative rotation.

[0004] Linear rails are linear guides, which are used to support and guide moving parts to perform reciprocating linear motion in a given direction. They are used in situations where high-precision linear reciprocating motion is required, and can bear a certain torque. Based on the high-precision guiding characteristics of the linear rails, the surface of the linear rails needs to be precisely ground after processing to ensure their guiding accuracy.

[0005] In the prior art, during the use of the grinding machine, when fixing the workpiece, most of the time, one end of the workpiece is clamped and fixed by a claw clamp to form a horizontal plane. Since only a single grinding surface can be processed at one time, for workpieces that need to process multiple grinding surfaces, multiple clamping and repeated positioning are required, which not only increases the number of workpiece clamping times and the risk of positioning errors, but also reduces the overall utilization rate of the equipment. Summary of the invention

Since the No. 1 mounting platform 13 is fixedly connected to the belt surface at the lower end of the connecting belt 1703, and the No. 2 mounting platform 15 is fixedly connected to the belt surface at the upper end of the connecting belt 1703, and the No. 1 mounting platform 13 and the No. 2 mounting platform 15 are dislocated up and down, the No. 1 mounting platform 13 will shrink and move downward during the alternating movement, so that the alternating position replacement of the No. 1 mounting platform 13 and the No. 2 mounting platform 15 will be completed when the connecting belt 1703 is running; Reference Figure 1-Figure 6 A No. 3 sliding groove 18 is provided at the midpoint of the upper end surface of the No. 1 mounting platform 13 and the No. 2 mounting platform 15. The No. 3 sliding groove 18 is arranged in the front-to-back direction and a No. 3 screw is arranged inside. A No. 3 motor is fixedly arranged at one end of the No. 3 screw. One of the two No. 2 fixing mechanisms 16 located on the upper end surface of the No. 1 mounting platform 13 or the No. 2 mounting platform 15 is threadedly sleeved with the No. 3 screw; that is, when in use, one of the two No. 2 fixing mechanisms 16 can first use the No. 3 motor to drive the No. 3 screw to rotate as needed to cause the No. 2 fixing mechanism 16 at the upper end to find a lateral displacement, thereby changing the distance between the two No. 2 fixing mechanisms 16 to complete the adjustment effect; Reference Figure 1, three electric slide rails 3 are fixedly arranged at the rear end of the upper end surface of the processing table 2, and a slider 4 is installed on the electric slide rail 3, a No. 1 sliding groove 5 is arranged on the upper end surface of the slider 4, and a No. 1 screw is installed in the No. 1 sliding groove 5, wherein one end of the No. 1 screw is fixedly provided with a No. 1 motor and a mounting seat 7 is threadedly sleeved on the outer side of the No. 1 screw, and a grinding component 6 is installed on the upper end of the mounting seat 7, a No. 2 sliding groove 10 is arranged at the front end of the upper end surface of the processing table 2, and a No. 2 screw is installed in the No. 2 sliding groove 10, wherein one end of the No. 2 screw is installed with a No. 2 motor and a No. 2 screw is threadedly sleeved on the outer side of the No. 1 screw, and a grinding component 6 is installed on the upper end of the mounting seat 7, A fixing block 8 is threadedly sleeved on the outer side of the screw rod, a connecting rod 9 is fixedly arranged on one side of the fixing block 8, and a No. 2 driving motor is installed inside one end of the connecting rod 9, wherein a grinding wheel 12 is fixedly arranged on the output end of the No. 2 driving motor; that is, when in use, after the No. 1 mounting table 13 or the No. 2 mounting table 15 is alternately replaced, the grinding assembly 6 and the grinding wheel 12 can be used to grind the inner wall and outer wall of the pipe fittings to be processed clamped between the two No. 1 fixing mechanisms 14 and the pipe fittings to be processed clamped between the two No. 2 fixing mechanisms 16 respectively; Reference Figure 1 and Figure 7 , two No. 1 fixing mechanisms 14 and two No. 2 fixing mechanisms 16 are installed on the upper end surfaces of the No. 1 mounting platform 13 and the No. 2 mounting platform 15. The No. 1 fixing mechanism 14 includes a base 1401, an auxiliary through cylinder 1402, a swivel 1403, a linkage ring 1404, six No. 1 mounting plates 1405, three fixing rods 1406, six No. 2 mounting plates 1407, three No. 3 mounting plates 1408, three adjusting screws 1409, three connecting outer rods 14010 and three inner blocks 14011. The auxiliary through cylinder 1402 is fixedly arranged on the upper end surface of the base 1401, and the six No. 1 mounting plates 1405 are divided into three groups in pairs and are arranged around the outer side of the linkage ring 1404 at an equidistant distance.

At this time, the outer swivel 1403 is rotated to make it displace on the body of the auxiliary cylinder 1402, and the linkage ring 1404 is displaced when the swivel 1403 is displaced. The linkage ring 1404 will continuously push the fixed rod 1406 to move during the displacement process. The fixed rod 1406 will generate a thrust on the No. 3 mounting plate 1408 during the movement to make it rotate on the inner side of the No. 2 mounting plate 1407. The No. 3 mounting plate 1408 drives the connected outer rod 14010 to rotate during the rotation, thereby realizing the rotation of the inner block 14011 at the lower end. Since three inner blocks 14011 are arranged on the outside, they all produce a central extrusion effect toward the axis core position of the auxiliary cylinder 1402 during the flipping process, thereby completing the positioning, calibration, extrusion and clamping effect of the pipe to be processed with the axis core of the auxiliary cylinder 1402 as the center point.

[0026] Reference Figure 1 and Figure 8 The second fixing mechanism 16 includes a rotating disk 1601, a fixed disk 1602, four bottom plates 1604, four extrusion plates 1605, multiple rotating shafts 1606, multiple movable rods 1607, four outer plates 1608 and an electric telescopic rod 1609.

One end of the electric telescopic rod 1609 is fixedly arranged at the midpoint of the fixed plate 1602 away from the rotating plate 1601. The multiple movable rods 1607 are grouped into four at each end, and both ends thereof are rotatably arranged at one side of the outer wall of the outer plate 1608 and one side of the outer wall of the bottom plate 1604 through the rotating shaft 1606; Specifically, the telescopic effect of the electric telescopic rod 1609 is used to drive the outer plate 1608 on the outside to move accordingly, and the outer plate 1608 will drive the movable rod 1607 connected to the outer side through the rotating shaft 1606 to move during the movement. Since the other end of the movable rod 1607 is also connected to the bottom plate 1604 and the bottom plate 1604 is slidably embedded in the slide groove 1603, the moving outer plate 1608 will pull the movable rod 1607 to change the inclination angle, and then pull the upper bottom plate 1604 to slide in the slide groove 1603. At the same time, since the bottom plate 1604 is fixed to the lower end of the extrusion plate 1605, when the bottom plate 1604 slides, the extrusion plate 1605 will slide synchronously, thereby changing the position of the extrusion plate 1605 to achieve expansion and contraction movements. When in the expansion movement, the distance to the inner wall of the pipe will continue to decrease until it is squeezed at the inner wall of the pipe to complete the auxiliary fixing effect.
