Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to multi-surface processing equipment. Background Art

[0002] On a production line, the processing of a workpiece is often not limited to one plane. Usually, multiple planes of a workpiece need to be processed. When the workpiece is flipped, multiple clamping mechanisms are required to cooperate, which is costly and has low flipping efficiency.

[0003] For example, a Chinese utility model patent with patent number CN202321637760.4 (publication number CN220516158U) entitled "A multi-sided processing equipment" discloses such a processing equipment, including a workbench and a processing head. The processing head can perform multi-sided processing on the workpiece on the workbench. The workbench is provided with a clamping seat for fixing the workpiece. The clamping seat can rotate under the action of a driving motor to switch the processing surface of the blank so that the processing head can perform multi-sided processing on the blank.

[0004] Although this type of equipment realizes multi-sided processing of the workpiece, the direction of the processing head used for processing is set perpendicular to the plane where the worktable is located, while the axial direction of the rotating shaft of the clamping seat is parallel to the plane where the worktable is located. Therefore, the switching of the processing surface in the blank can only be around the axial direction of the rotating shaft of the clamping seat.

[0005] However, if the workpiece to be processed is Figure 1 The steam oven inner pot 1' shown in the figure will have another processing problem. One surface of the steam oven inner pot 1' is a hollow surface. Opposite to the hollow surface is a first processing surface 11' for heat dissipation. The hollow surface and the first processing surface 11' respectively form a second processing surface 12', a fourth processing surface 14', a fifth processing surface 15' and a third processing surface 13' for connecting the two in the upper, lower, left and right directions. When the above processing equipment is used for processing, the hollow surface and the first processing surface 11' of the steam oven inner pot need to be arranged in a direction parallel to the axial direction of the rotating shaft of the clamping seat. When the clamping seat rotates around the rotating shaft, the process can only complete the processing of each processing surface in one dimension (X), that is, the first processing surface 11', the second processing surface 12' and the fourth processing surface 14' are processed, while the third processing surface 13' and the fifth processing surface 15' that can rotate in another dimension (Z) cannot be processed. At this time, the processing equipment cannot meet the processing requirements.

[0006] In summary, the prior art needs to be further improved. Utility Model Content

DETAILED DESCRIPTION

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] During the processing of the workpiece 5, the workpiece 5 needs to be clamped and fixed. There are many ways to fix the workpiece 5, such as placing the workpiece 5 in a clamping groove or using a clamping block and a clamping cylinder to fix the workpiece 5. However, the above methods have certain disadvantages, such as shielding the processing surface and causing a certain processing surface to be unable to be processed. On the basis of ensuring the clamping force of the workpiece 5, refer to Figure 4 and Figure 5In this embodiment, the preferred clamping assembly 2 includes a panel 21 and two clamping arms 22. The clamping arms 22 are arranged on the side of the panel 21. The clamping arms 22 and the panel 21 are surrounded to form an open space for clamping the workpiece 5. The first processing surface 51 and the second processing surface 52 are both exposed to the processing environment. The clamping arm 22 includes a fixed portion 221 and a movable portion 222. One end of the fixed portion 221 is vertically arranged on the panel 21 along the axis A, and the other end of the fixed portion 221 is hinged to the movable portion 222. One surface of the workpiece 5 contacts the panel 21, and the clamping arms 22 located on both sides cooperate and apply force to fix the workpiece 5 in the space. The clamping arms 22 are slender as a whole, and the processing surface of the workpiece 5 is exposed to the processing environment, which is convenient for the processing head to process. The fixed portion 221 of the clamping arm 22 abuts against the side of the workpiece 5, and the movable portion 222 can be adjusted by rotating the position. According to the size or material of the workpiece 5, the angle between the movable portion 222 and the fixed portion 221 can be adjusted accordingly, so as to adjust the clamping force to the optimal state.

[0033] During the processing, the processing head is usually fixed at a certain height from the workbench 1, and the workpiece 5 needs to adjust the processing surface to a fixed position below the processing table for processing. In order to achieve a certain preset height between the workpiece 5 and the workbench 1 so as to be closer to the processing head, refer to Figures 2 to 6 The connecting member is a bracket 3 vertically arranged on the workbench 1 in the direction Y, and the bracket 3 includes a vertical portion 32 vertically arranged on the workbench 1, and a horizontal portion 31 rotatably connected to the vertical portion 32. The vertical portion 32 is a column with a certain height, and the horizontal portion 31 is arranged at the top of the vertical portion 32. Therefore, the horizontal portion 31 and the clamping assembly 2 rotatably connected to the horizontal portion 31 maintain a certain preset height with the workbench 1, and the workpiece 5 in the clamping assembly 2 can be closer to the processing head above, so as to facilitate processing.

[0034] The workpiece 5 to be processed has many shapes, such as a cuboid, a pentagonal prism, etc. This embodiment is described by taking a cuboid steam oven inner pot as an example. Figure 1The inner pot of the steam oven is composed of 6 surfaces, one of which is a hollow surface. The surface opposite to the hollow surface is a heat dissipation surface covered with mesh holes, namely, a first processing surface 51. The first processing surface 51 is perpendicular to the axis A and can rotate along the axis B. Four side surfaces connecting the two are arranged between the hollow surface and the first processing surface 51. The four side surfaces together constitute a second processing surface 52, and the second processing surface 52 can rotate along the axis A. In order to achieve rotational freedom in two dimensions, the control device 4 includes a first rotating shaft assembly 41 including an axis A and a second rotating shaft assembly 42 including an axis B. The first rotating shaft assembly 41 and the second rotating shaft assembly 42 are both connected to the output end of the power source, and the axis A is perpendicular to the axis where the transverse portion 31 is located. The first rotating shaft assembly 41 rotates around the axis A under the drive of the power source. At this time, the clamping assembly 2 rotates relative to the transverse portion 31, so that the second processing surface 52 can cooperate to complete the change of the rotation angle, and then process the various different parts on the second processing surface 52; the axis B is parallel to the axis where the transverse portion 31 is located, one end of the second rotating shaft assembly 42 is hinged to the transverse portion 31, and the other end is hinged to the seat body 11 protruding upward from the processing platform. The second rotating shaft assembly 42 cooperates with each other under the drive of the power source to drive the transverse portion 31 and the clamping assembly 2 to rotate around the axis B relative to the workbench 1, so that each processing surface can be rotated to a fixed position below the processing head, thereby facilitating processing. The second rotating shaft assembly 42 includes a first rotating arm 421 and a second rotating arm 422 which are hinged to each other. The first rotating arm 421 and the second rotating arm 422 are respectively set at an inclination angle α and an inclination angle β with the axis A and are hinged to each other. The inclination angle α of the first rotating arm 421 can be adjusted in the range of 50° to 60°, and the inclination angle β of the second rotating arm 422 can be adjusted in the range of 45° to 60°. By adjusting their own inclination angles, the first rotating arm 421 and the second rotating arm 422 can cooperate with each other to drive the transverse portion 31 to rotate along the axis B.

[0035] Since the position of the machining head is fixed, in order to ensure the machining quality, the workpiece 5 must be accurately rotated to the fixed position. Figure 5 and Figure 7, a limit rod 3111 for limiting the rotation angle of the clamping assembly 2 is provided on the transverse portion 31, and a limit block group 211 is provided on one side of the panel 21 close to the transverse portion 31. The preferred limit block group 211 in this embodiment includes 4 limit blocks, which are respectively arranged on the upper, lower, left and right sides of the panel 21 to respectively correspond to the rotation angles of 90°, 180°, 270° and 360° on the second processing surface 52 of the steam oven inner tank. The limit block group 211 is provided with a concave limit groove 2111, and the limit groove 2111 cooperates with the limit rod 3111 to enable the clamping assembly 2 to rotate to a preset angle. After the clamping assembly 2 rotates to a preset angle along the axis A, the limit rod 3111 moves into the limit groove 2111, at which time the entire clamping assembly 2 stops moving, and the processing surface is accurately rotated to just below the processing head.

[0036] The specific working steps of the multi-faceted processing equipment in this embodiment are as follows: place the steam oven inner container in the clamping assembly 2, wherein the hollow surface of the inner container contacts the panel 21, the fixed portion 221 of the clamping assembly 2 abuts against the side of the inner container, and the movable portion 222 adjusts the angle to apply force to the first processing surface 51 to clamp the entire workpiece 5. Turn on the power source switch, at this time, a part of the second processing surface 52 is located below the processing head, and the part is processed first. After the processing is completed, the first rotating shaft assembly 41 is driven by the power source to rotate 90°, 180°, 270° and 360° around the axis A in sequence. Each time it rotates, the limit rod 3111 and the limit groove 2111 cooperate with each other to make the processing surface accurately rotate to the right below the processing head and perform corresponding processing. After the second processing surface 52 is processed, the second rotating shaft assembly 42, driven by the power source, drives the transverse part 31 and the clamping assembly 2 to rotate relative to the workbench 1 around the axis B, and the first processing surface 51 is rotated to the bottom of the processing head. After the processing is completed, the second rotating shaft assembly 42 drives the transverse part 31 and the clamping assembly 2 to rotate in the opposite direction to complete the reset. Finally, adjust the movable part 222 to remove the steam oven inner shell.
