Description

Technical Field

[0001] The present application relates to the technical field of processing, and in particular to a processing component and processing equipment. Background Art

[0002] Curved rollers are widely used in various fields, such as mechanical engineering, transportation equipment, and aerospace. Their working principle is simple and intuitive, and they can achieve high-precision and high-speed control. As the capacity of paper machines continues to increase and the speed of machines increases, the rollers will wear out during the operation of the mesh due to inaccurate curvature and non-center inner holes, which greatly shortens the service life of the curved rollers and requires frequent replacement to meet production needs. At the same time, rollers are also used in other parts of papermaking equipment, such as spray rollers, inner and outer curvature pulleys, etc. Because the rollers in some scenes are long in length and small in diameter, they are prone to local deformation, and the size, curvature, and material of rollers in different positions are generally non-standard sizes, so they need to be processed independently according to the working conditions.

[0022] The embodiments of the present application provide a processing component 10. Please refer to Figures 1 to 3, the processing assembly 10 includes a bracket 110 and a turning tool unit 120. The bracket 110 is provided with a processing area 1101; the turning tool unit 120 is rotatably connected to the bracket 110. The turning tool unit 120 includes a turning tool 121 and an adjusting member 122. The turning tool 121 is provided with a tool tip 1211, and the tool tip 1211 extends into the processing area 1101; the adjusting member 122 is connected to one end of the turning tool 121 away from the tool tip 1211, and the adjusting member 122 is used to adjust the distance that the tool tip 1211 extends into the processing area 1101.

[0023] During the operation of the paper machine wire cloth, if the traveling direction of the roller 30 is not perpendicular to the direction of the unfolding force, the tension is unevenly diffused, and the roller 30 will produce an eight-shaped fold due to the inaccurate radian of the groove 310 of the roller 30, resulting in wear. If the lowest point of the groove 310 is not on the center line of the groove 310, and the inner hole of the roller 30 is not centered, it will also cause the wear to accelerate, further shortening the service life of the roller 30 significantly, and it needs to be frequently replaced to meet the production requirements. At the same time, the dimensions, radians, materials, etc. of the rollers 30 at different positions are generally non-standard sizes, so they need to be processed independently according to the working conditions. The processing assembly 10 in this application can be used to process the roller 30, and the turning tool 121 can cut the roller 30 to form the groove 310 of the roller 30. The roller 30 can be installed in the processing area 1101. The turning tool unit 120 is rotatably connected to the bracket 110. During the rotation of the turning tool unit 120, the tool tip 1211 can move along an arc trajectory to mill the roller 30 in the processing area 1101 to form an arc-shaped groove 310, that is, the groove 310 forms an arc shape in the cross-section passing through the axis of the roller 30. The adjusting member 122 can adjust the length that the tool tip 1211 extends into the processing area 1101, and can finely adjust the feed to ensure that the radian accuracy of the groove 310 is below 0.03 mm, meeting the on-site use requirements.

[0024] Optionally, the processing assembly 10 further includes a rotating shaft 130. The turning tool unit 120 penetrates the side surface of the rotating shaft 130, and the rotating shaft 130 is rotatably connected to the bracket 110. The rotating shaft 130 is used to drive the turning tool unit 120 to rotate.

[0025] Optionally, the bracket 110 includes a first arm 111 and a second arm 112 arranged oppositely, and a third arm 113 connected between the first arm 111 and the second arm 112. The two ends of the rotating shaft 130 are respectively connected to the first arm 111 and the second arm 112. The rotating shaft 130, the first arm 111, the second arm 112 and the third arm 113 cooperate to form the processing area 1101. Further, the third arm 113 and the rotating shaft 130 can be respectively located at both ends of the first arm 111, and the rotating shaft 130, the first arm 111, the second arm 112 and the third arm 113 can enclose a rectangular shape.

[0026] Optionally, one end of the rotating shaft 130 is connected with a handwheel 140. The handwheel 140 is located on the side of the first arm 111 away from the processing area 1101, and the handwheel 140 is used to drive the rotation of the rotating shaft 130. The handwheel 140 and the rotating shaft 130 are fixedly connected. The staff can control the rotation angle of the turning tool unit 120 through the handwheel 140 to cut different positions of the roller 30. In actual work, the distance between the axis of the roller 30 and the rotating shaft 130 remains unchanged, and the axis direction of the roller 30 is perpendicular to the axis direction of the rotating shaft 130. The height of the axis of the roller 30 is the same as the height of the turning tool unit 120, and the two are on the same horizontal plane. The tool tip 1211 moves from one end of the arc to the other end of the arc to cut the roller 30 to form a groove 310, which can ensure that the lowest point of the groove 310 is located on the center line of the groove 310, that is, the shape of the groove 310 is symmetric.

[0027] Furthermore, the turning tool unit 120 includes a locking member 123. The locking member 123 is located on the side of the rotating shaft 130, and the locking member 123 is used to fix the distance that the tool tip 1211 extends into the processing area 1101. During the rotation of the turning tool unit 120 relative to the bracket 110, the turning tool unit 120 rotates around the rotating shaft 130 to lock the distance that the tool tip 1211 extends into the processing area 1101, that is, to lock the radius of the arc formed by the rotation of the tool tip 1211.

[0028] Optionally, the rotating shaft 130 is provided with an installation channel 1301. The installation channel 1301 penetrates the side of the rotating shaft 130. The turning tool unit 120 is inserted into the installation channel 1301. A locking hole 1302 is provided on the side of the rotating shaft 130. The locking hole 1302 communicates with the installation channel 1301, and the locking member 123 is inserted into the locking hole 1302.

[0029] Furthermore, an installation pipe 131 is provided on the side of the rotating shaft 130. An installation channel 1301 is provided inside the installation pipe 131, and at least part of the turning tool unit 120 is installed inside the installation pipe 131.

[0030] Furthermore, the locking member 123 can be a set screw. When it is necessary to lock the distance that the tool tip 1211 extends into the processing area 1101, the locking member 123 can press against the adjusting member 122 or the turning tool 121 inside the installation channel 1301 to fasten the turning tool 121 and limit the movement of the tool tip 1211.

[0031] Optionally, bearings 150 are provided at both ends of the rotating shaft 130. The rotating shaft 130 is rotatably connected to the first arm 111 and the second arm 112 through the bearings 150 respectively. The number of the bearings 150 can be two. One of the bearings 150 can be located between one end of the rotating shaft 130 and the first arm 111, and the other bearing 150 can be located between the other end of the rotating shaft 130 and the second arm 112.

[0032] Optionally, the adjusting member 122 includes a sleeve 1221 and a differential barrel 1222. The sleeve 1221 is fixedly connected to the rotating shaft 130. The differential barrel 1222 is sleeved on the sleeve 1221 and is rotatably connected to the sleeve 1221. During rotation, the differential barrel 1222 can drive the turning tool 121 to move along the axis direction of the differential barrel 1222. A differential scale 1223 is provided on the differential barrel 1222.

[0033] Further, the adjusting member 122 further includes a screw rod (not shown in the figure). The screw rod is fixedly connected to the differential barrel 1222, passes through the sleeve 1221 and is fixedly connected to the turning tool 121. When the locking member 123 locks the distance that the cutting head 1211 extends into the processing area 1101, it can abut against the screw rod or the turning tool 121.

[0034] Further, the sleeve 1221 can be fixed to the mounting pipe 131. Female threads are engraved in the sleeve 1221, and male threads are engraved on the outside of the screw rod. When the differential barrel 1222 rotates relative to the sleeve 1221, the screw rod also rotates relative to the sleeve 1221, and the rotational motion is converted into a linear motion, thereby realizing the forward or backward movement of the screw rod.

[0035] Further, the scale on the differential scale 1223 can be 50 equally divided scales. When the differential barrel 1222 rotates one full circle, the displacement of the cutting head 1211 changes by 0.5 mm. That is, when the differential scale rotates one grid, the displacement of the cutting head 1211 changes by 0.01 mm, that is, the processing accuracy is as high as 0.01 mm.

[0036] Specifically, the function of the adjusting member 122 can be similar to that of an outside micrometer. An outside micrometer, also called a screw micrometer, is often simply referred to as a "micrometer". The screw micrometer is made based on the principle of screw amplification, that is, when the measuring screw rotates one full circle in the nut, the measuring screw advances or retreats a distance equal to one pitch along the axis of rotation. Therefore, a small distance moved along the axis direction can be represented by the reading on the circumference. The pitch of the precision thread of the screw micrometer is 0.5 mm, and the movable scale has 50 equally divided scales. When the movable scale rotates one full circle, the measuring screw can advance or retreat 0.5 mm. Therefore, when rotating each small division, it is equivalent to the measuring screw advancing or retreating 0.5 / 50 = 0.01 mm. It can be seen that each small division of the movable scale represents 0.01 mm, so the screw micrometer can be accurate to 0.01 mm. Since it can be estimated to one more digit and can be read to the thousandth place of a millimeter, it is also called a micrometer.

[0037] The embodiment of the present application also provides a processing device. The processing device includes the processing component 10 in the above embodiment, and the processing device further includes a lathe 20. The processing component 10 is installed on the lathe 20.

[0038] Optionally, the processing device is used to process the roller 30. The roller 30 is located in the processing area 1101. The lathe 20 includes a tool rest 210. The bracket 110 includes a connecting arm 114. The connecting arm 114 is fixedly installed on the tool rest 210. The length direction of the connecting arm 114 is perpendicular to the axis direction of the roller 30. The lathe 20 further includes a carriage 220. The tool rest 210 is fixedly installed on the carriage 220. The carriage 220 can move along the length direction of the connecting arm 114.

[0039] Furthermore, the connecting arm 114 can be connected to the side of the third arm 113 facing away from the processing area 1101. The connecting arm 114 can be connected to the middle of the third arm 113, making the shape of the bracket 110 symmetrical.

[0040] Specifically, three bolts on the tool rest 210 can be used to fixedly connect the connecting arm 114, making the length direction of the rotating shaft 130 parallel to the vertical direction. The length directions of the first arm 111 and the third arm 113 are respectively perpendicular to the axis direction of the roller 30. After the processing assembly 10 is installed on the lathe 20, the height of the turning tool unit 120 should be flush with the axis of the roller 30.

[0041] Furthermore, the lathe 20 further includes a chuck 230. The workpiece to be processed is fixed on the chuck 230. The chuck 230 can drive the roller 30 to rotate around the axis of the roller 30. At this time, by rotating the handwheel 140 of the processing assembly 10, a groove 310 can be cut on the side surface of the roller 30.

[0042] In some embodiments, the processing assembly 10 can also be used to repair the roller 30, restoring the groove 310 of the roller 30 to the expected optimal arc state.

[0043] Furthermore, the lathe 20 further includes a tailstock 240. The tailstock 240 is used to fix the rear end of the workpiece to be processed and keep the length direction of the workpiece parallel to the horizontal plane.

[0044] During the actual working process, a measuring dial indicator can be used to measure the parallelism of the workpiece to be processed. The measuring dial indicator is a national standard measuring tool. The measuring dial indicator can be installed at the end face of the straightening unit of the lathe 20. Move the measuring dial indicator and record the bending change curve of the workpiece, and adjust the workpiece to keep it horizontal.

[0045] Optionally, the carriage 220 can drive the tool bit 1211 to move towards the roller 30 to control the arc depth of the groove 310. The adjusting member 122 can further perform fine adjustment to realize the adjustment of the arc length of the cross section of the groove 310.

[0046] Furthermore, the control from rough feed to fine feed can be achieved through the handwheel 140. When the handwheel 140 rotates quickly, rough machining can be performed. When the handwheel 140 rotates slowly, fine machining can be performed to improve the machining accuracy. This can effectively solve the problems that when the traveling direction of the roller 30 is not perpendicular to the direction of the unfolding force, due to uneven tension diffusion, the roller 30 generates an eight-shaped wrinkle due to inaccurate arc, resulting in wear, and the wear is accelerated due to the non-centering of the inner hole of the roller 30. In this application, the wear deformation amount of the roller 30 can be optimized from 3 mm to 5 mm to within 0.1 mm. The service life of the equipment is increased by about 35% compared with the previous one, and the equipment cost is reduced by about 60%. Good working effects have been achieved in actual production.

[0047] Optionally, in some other embodiments, the handwheel 140 can also be replaced with a control motor. The control motor is connected to the rotating shaft 130 and is used to control the rotation speed of the rotating shaft 130 to achieve automated machining.

[0048] The processing component 10 and the processing equipment provided by this application can achieve feed control by using the adjusting member 122, and can process the roller 30 with grooves 310 of different arcs to meet different production requirements. The setting of the processing component 10 enables the arc dimension accuracy of the processed roller 30 to be within 0.03 mm, the qualified rate of the finished product can reach about 98%, the arc accuracy rate can reach 95%, and the service life of the roller 30 can be increased by about 20% compared with the previous one. It can reduce the labor cost and the arc error rate, and restore the roller 30 to the expected best arc state, improve the machining accuracy of the equipment, simplify the processing process, and is beneficial to improving the qualified rate and production efficiency of the product.

[0049] The above are only some embodiments of this application, and thus do not limit the protection scope of this application. Any equivalent device or equivalent process transformation made by using the content of the specification and drawings of this application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of this application.
