[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0041] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0042] In the related prior art, refer to Figure 4The production and processing of wheel hubs are divided into one-sequence processing, two-sequence processing and three-sequence processing in the shape of finished products. One-sequence processing is to cut the outer rim, inner rim, center hole, flange surface, inner spoke, etc. of the wheel hub blank to achieve the set dimensional accuracy. The two-sequence processing is mainly to process the areas that cannot be processed due to clamping during the first-sequence processing, such as the circumferential surface clamped by the fixture, the bottom surface of the wheel hub blank in the first-sequence processing, etc. The three-sequence processing is to process the holes of the wheel hub, such as valve holes and bolt holes. Since the processing area of ​​the first-sequence processing is large and the processing holes of the three-sequence processing are many, in actual processing, the time of the second-sequence processing operation is the shortest. After the second-sequence processing is completed, it is necessary to wait for the third-sequence processing, which affects the production rhythm of the wheel hub and restricts the improvement of production efficiency.

[0043] To this end, the utility model provides a wheel hub two-sequence processing equipment, which can perform part of the three-sequence processing operations, thereby adjusting the overall processing rhythm and improving production efficiency.

[0044] Reference Figures 1 to 4 A wheel hub two-sequence processing equipment according to an embodiment of the utility model comprises a bed 100 and a workpiece box 102, a turret processing mechanism 200 and a drilling mechanism 300 arranged on the bed 100. The workpiece box 102 is provided with a workpiece spindle and a workpiece fixture located at the end of the workpiece spindle for clamping the workpiece. It can be understood that the workpiece is the wheel hub. The turret processing mechanism 200 can at least be adjusted to move laterally in the X direction and vertically in the Z direction relative to the workpiece box 102, so as to realize processing feed or move away from the workpiece box 102. Similarly, the drilling mechanism 300 can at least be adjusted to move laterally in the X direction and vertically in the Z direction relative to the workpiece box 102, so as to realize drilling processing on the workpiece.

[0045] The workpiece spindle drive on the workpiece box 102 can be set with reference to the spindle box structure in the related prior art. The workpiece fixture arranged at the end can be set according to the shape and specification of the wheel hub to be processed, such as a three-jaw chuck structure clamped on the circumferential side, a three-jaw chuck structure held from the inside of the wheel hub to the outside, a pressure block structure locked along the axial direction of the wheel hub, etc. Those skilled in the art can flexibly set it according to actual needs, and no specific limitation is made here. The turret processing mechanism 200 can adopt a traditional turret structure, that is, a cutter disc 202 is rotatably arranged, and multiple tools 203 are arranged on the circumference of the cutter disc 202. Different tools 203 are switched by rotating the cutter disc 202, and the axial direction of the tool 203 in the processing position is kept consistent with the axial direction of the wheel hub. The drilling mechanism 300 performs drilling operations through a drill bit (also called a milling head). The drill bit of the drilling mechanism 300 can be replaced to realize the processing of bolt holes, valve holes or other hole positions of the wheel hub.

[0046] Reference Figures 1 to 3In order to facilitate loading and unloading of the wheel hub and chip removal during processing, the turret processing mechanism 200 and the drilling mechanism 300 are arranged above the workpiece box 102. In this way, the turret processing mechanism 200 and the drilling mechanism 300 only need to move downward to dock the workpiece, and the waste chips generated during processing can be directly discharged from the bottom without affecting the turret processing mechanism 200 and the drilling mechanism 300.

[0047] It can be understood that the wheel hub two-sequence processing equipment in the present invention is provided with both a turret processing mechanism 200 and a drilling mechanism 300. When the wheel hub to be processed is loaded onto the workpiece box 102, the traditional two-sequence processing operation can be performed by the turret processing mechanism 200. After the processing is completed, the drilling mechanism 300 is further used to perform hole processing, and part of the hole positions of the three-sequence processing in the traditional process are directly completed in the two-sequence processing. Therefore, the present invention proposes a processing equipment different from the traditional two-sequence structure design, which can perform part of the three-sequence processing operation. In the production process, it helps to shorten the three-sequence processing cycle, thereby adjusting the overall processing rhythm of the wheel hub and improving production efficiency.

[0048] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the bed 100 is provided with an XYZ three-axis transmission mechanism 101, and the turret processing mechanism 200 and the drilling mechanism 300 are both connected to the XYZ three-axis transmission mechanism 101, so as to perform lateral movement adjustment, longitudinal movement adjustment and vertical movement adjustment relative to the workpiece box 102 along the X direction, the Y direction and the Z direction. The X direction is the left and right direction of the bed 100, the Y direction is the front and back direction of the bed 100, and the Z direction is the vertical direction of the bed 100. With the structural setting of this embodiment, the XYZ three-axis transmission mechanism 101 can be used to simultaneously realize the XYZ three-axis movement adjustment of the turret processing mechanism 200 and the drilling mechanism 300, and the movement adjustment in three directions can improve the docking matching degree between the turret processing mechanism 200 and the drilling mechanism 300 and the workpiece respectively. Furthermore, in actual processing, the wheel hub rotates when the turret processing mechanism 200 is operating, and the drill bit rotates when the drilling mechanism 300 is drilling, so the processing operations of the two can be performed successively. An XYZ three-axis transmission mechanism 101 is used to control the movement and adjustment of the two, which can not only meet the movement and adjustment of the turret processing mechanism 200 and the drilling mechanism 300, but also help to optimize the structural setting, reduce the structural composition, and thus reduce the equipment cost. It is understandable that since the second-order processing time is shorter than the third-order processing time in the traditional process, when the turret processing mechanism 200 and the drilling mechanism 300 are controlled to operate successively, the overall processing time will not increase.

[0049] Reference Figure 1In some embodiments of the present invention, the turret processing mechanism 200 includes a turret box 201, which is connected to the adjustment output end of the XYZ three-axis transmission mechanism 101, and the drilling mechanism 300 is connected to the side wall of the turret box 201. In this way, the movement of the turret processing mechanism 200 and the drilling mechanism 300 can be controlled simultaneously by only controlling the movement and adjustment of the turret box 201.

[0050] Reference Figure 1 and Figure 3 In some embodiments of the utility model, both the turret box 201 and the workpiece box 102 protrude forward relative to the bed 100, and the turret box 201 and the workpiece box 102 are distributed up and down, wherein the turret box 201 is higher than the workpiece box 102. The bed 100 is provided with a swing spindle, and the workpiece box 102 is connected to the front end of the swing spindle and keeps the workpiece spindle perpendicular to the swing spindle. With the structural setting of this embodiment, the workpiece box 102 can swing left and right through the swing spindle, thereby adjusting the angle of the workpiece so that its axis can swing relative to the vertical direction, so as to facilitate the processing of inclined holes. And the protruding setting relative to the bed 100 is convenient for chip removal and can be close to the worker's operating area for easy viewing by the worker.

[0051] Reference Figure 1 In some embodiments of the present invention, the wheel hub second-stage processing equipment further includes a loading robot 400, which is disposed on the bed 100 and is at least used to load the workpieces in the workpiece box 102. Figure 1 The loading robot 400 is installed on the side wall of the turret box 201, and is arranged on both sides of the turret box 201 with the drilling mechanism 300. In this way, the movement and adjustment of the loading robot 400 can be achieved by utilizing the movement and adjustment of the turret box 201, and the hub two-stage processing equipment arranged in this way has a stronger integrity.

[0052] Reference Figures 1 to 3In some embodiments of the utility model, the turret processing mechanism 200 includes a turret box 201, and the feeding manipulator 400 includes a mounting portion 401, a swinging assembly and a clamping assembly, wherein the mounting portion 401 is fixedly arranged on the side wall of the turret box 201. Since the size of the cutter head 202 of the turret processing mechanism 200 will extend horizontally outward by a certain length after the tool 203 is installed, in order to avoid interference with the tool 203, the mounting portion 401 is an inverted L-shaped structure, so as to maintain a certain distance between the turret box 201 and reserve enough space. The lower end of the mounting portion 401 extends downward to be lower than the turret box 201. The swinging assembly can be rotatably connected to the bottom of the mounting portion 401 around a vertical axis. The clamping assembly can be arranged on the side of the swinging assembly in a horizontal opening and closing manner, for clamping or releasing the workpiece. During operation, the clamping assembly can move the workpiece to the workpiece box 102 or away from the workpiece box 102 by the swinging of the swinging assembly, which is conducive to reducing the movement and adjustment stroke of the turret box 201. Furthermore, due to the arrangement of the mounting portion 401, the workpiece can be moved outward by swinging the clamping assembly, thereby preventing the mounting portion 401 from interfering with other structures when the loading robot 400 is loading and removing parts.

[0053] In some embodiments of the present invention, reference Figure 3 The clamping assembly includes two clamping arms 404, which are arranged on the swinging assembly so as to be movable horizontally toward each other. Two clamping rods 405 are vertically arranged on each clamping arm 404, and the two clamping rods 405 are arranged at intervals. A clamping block 406 is arranged on each clamping rod 405, and the clamping block 406 is a rotating body structure, and a groove is arranged around the clamping rod 405. When working, the clamping assembly clamps the workpiece from both sides through the two clamping arms 404. When clamping, the grooves of the four clamping blocks 406 are used to clamp the edge of the wheel hub to ensure stability during clamping.

[0054] It should be noted that the number of the clamping block 406 can be flexibly set as needed and is not limited to one. In this embodiment, the clamping block 406 is set as a rotating body structure and is installed by sleeve-mounting on the clamping rod 405, so that it can rotate when clamping the workpiece to avoid damaging the surface of the workpiece after processing. And the material of the clamping block 406 can be set as an iron structure or a plastic structure as needed. When a plastic structure is used, it can effectively avoid scratching the surface of the workpiece. For example, a polyurethane structure is used.

[0055] Specifically, refer to Figure 1The lower end of the mounting portion 401 is horizontally extended along a side close to the turret box 201 to provide a support plate 402, and the swing assembly includes a rotating seat 403 rotatably provided at the bottom of the end of the support plate 402. Two clamping arms 404 are slidably provided on the rotating seat 403. In order to drive the two clamping arms 404 to move synchronously in opposite directions, the rotating seat 403 can be provided with a double-headed cylinder for driving control, or a gear double rack structure can be used for driving, which is not specifically limited here.

[0056] Furthermore, a floating module is configured between the rotating seat 403 and the support plate 402, so that the rotating seat 403 can deflect and float relative to the support plate 402 in an angular manner. The floating module can adopt the structural setting of the relevant prior art, and will not be described in detail here. By configuring the floating module in this embodiment, when the workpiece is clamped for installation, the smoothness of the workpiece installation can be improved to avoid interference damage.

[0057] In some embodiments of the present invention, reference Figure 2 The wheel hub secondary processing equipment further includes a material unloading manipulator 500, which is disposed on the bed 100 and is used to unload the workpiece from the workpiece box 102. Specifically, the material unloading manipulator 500 includes a horizontal truss 501 connected to the bed 100, an adjustment seat 502 slidably disposed on the horizontal truss 501, and a clamping jaw 503 disposed on the adjustment seat 502. The structural setting of the clamping jaw 503 can be the structural setting of the clamping assembly. In this way, after the wheel hub secondary processing equipment completes the processing, the workpiece can be taken away and sent out by using the clamping jaw 503.

[0058] In order to further improve processing efficiency, refer to Figure 3 In this embodiment, the wheel hub second-order processing equipment further includes a side processing mechanism 600, which is arranged on the side of the workpiece clamping area of ​​the workpiece box 102, and the side processing mechanism 600 is provided with a side tool that can be longitudinally moved and adjusted at least along the Y direction. With the structural arrangement of this embodiment, when the turret processing mechanism 200 performs processing from above, the side processing mechanism 600 can control the side tool feed, and perform turning processing on the wheel hub from another position, thereby improving processing efficiency.

[0059] Specifically, the side processing mechanism 600 is also equipped with a three-axis moving mechanism for XYZ movement adjustment, and a tool holder is configured at the adjustment output end of the three-axis moving mechanism, and multiple side tools are arranged side by side along the X direction on the tool holder. Since the wheel hub rotates on the workpiece spindle, the tool holder can adjust any side tool to align the quadrant point position of the wheel hub by moving in the X direction, and then feed the wheel hub to achieve processing. Setting multiple side tools can realize the pre-installation of tools of different categories, saving the time of tool change.

[0060] Reference Figure 1In some embodiments of the present invention, the wheel hub secondary processing equipment further includes a chip conveyor 103, which is disposed below the workpiece box 102 and is used to promptly discharge waste chips generated during processing. The chip conveyor 103 can be a conventional structure and is not specifically limited here.

[0061] Reference Figures 1 to 3 In some embodiments of the utility model, the wheel hub second-order processing equipment includes a bed 100, a turret processing mechanism 200, a drilling mechanism 300, a workpiece box 102 and a side processing mechanism 600, wherein a swing spindle is arranged on the bed 100 along the front-to-back direction, the workpiece box 102 is fixed at the front end of the swing spindle, the workpiece spindle is arranged in the workpiece box 102 along the axial direction perpendicular to the swing spindle, one end of the workpiece spindle extends out of the workpiece box 102 and a workpiece fixture is arranged. The bed 100 is provided with a clearance opening at a position above the swing spindle and opposite to the area when the workpiece is installed in the workpiece box 102, and the side processing mechanism 600 is arranged in the clearance opening, including a three-axis moving mechanism and a tool holder, and the tool holder can be moved and adjusted in three directions of up and down, front and back, and left and right through the three-axis moving mechanism. A plurality of side tools can be detachably installed on the tool holder along the left and right directions. The bed 100 is provided with an XZ two-axis transmission mechanism above the clearance opening, and the turret processing mechanism 200 is installed on the XZ two-axis transmission mechanism to realize left and right, up and down movement adjustment. The turret processing mechanism 200 is provided with a turret box 201, and a cutter head 202 spindle is provided on the turret box 201. A cutter head 202 is provided at the lower end of the cutter head 202 spindle. A plurality of tools 203 are provided circumferentially on the cutter head 202. The angle between the cutter head 202 spindle and the tool 203 satisfies: the angle between the tool 203 and the center of the cutter head 202 is equal to the angle between the cutter head 202 spindle and the vertical direction, so that the tool 203 is vertically downward when it rotates to the processing position. The drilling mechanism 300 is provided on the right side wall of the turret box 201, and a drill is provided downward. The turret box 201 and the workpiece box 102 maintain the consistency of the axis along the front and back direction during installation to ensure that automatic centering can be achieved only by left and right adjustment.
