Description

Technical field:

[0001] The utility model relates to the technical field of wheel hub processing equipment, and more specifically to a rotating table device for wheel hub processing. Background technology:

[0002] When machining existing wheel hubs, one part needs to be machined on a machining center or CNC machine tool, and then it needs to be moved to another machining center or CNC machine tool to process another part. The existing loading and unloading operations are all carried out by six-axis robots.

[0003] However, after a workpiece is processed once, its surface needs to be cleaned to ensure the normal progress of subsequent processing. Otherwise, the waste cuttings on its surface will block the tool for subsequent processing, causing tool damage and reduced processing accuracy.

[0004] Therefore, the existing method is generally that a six-axis robot takes out a wheel hub processed in a machining center or a CNC machine tool, places it on a table set in the middle, and performs manual blow-cutting. After completion, the wheel hub is grabbed and placed in a machining center or CNC machine tool that needs to be processed later. However, the existing table is an ordinary flat surface, and its height cannot be adjusted. Moreover, there is no prompt after placement. When the operator is not next to the table, after the six-axis robot places the wheel hub, regardless of whether it is blown or not, when the specified time comes, the wheel hub on the platform will be grabbed and transported to the subsequent machining center or CNC machine tool for processing, resulting in omissions and affecting the subsequent processing effect. Utility model content:

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a turntable device for wheel hub processing, wherein the upper horizontal support plate can be adjusted in height to meet the needs of operators with different heights, and after the wheel hub is placed, the proximity switch can sense the wheel hub and transmit a signal to a control host, which will remind the operator to blow air on the wheel hub to remove debris, etc. The utility model is easy to operate, has a good effect, and ensures that nothing is missed.

[0006] The solution of the utility model to solve the technical problem is:

[0007] A turntable device for wheel hub processing includes a vertical support column, a fixing plate at the bottom end of the vertical support column is fixed to the ground, a vertical lifting screw is installed on the vertical support column, a horizontal fixing plate is fixed to the top end of the vertical lifting screw, a proximity switch is fixed to the top surface of the edge of the horizontal fixing plate, an upper horizontal support plate that can be adjusted up and down is installed above the horizontal fixing plate, and the bottom surface of the upper horizontal support plate is close to the sensing end of the top end of the proximity switch.

[0008] A screw connection hole extending vertically downward is formed in the middle of the top surface of the vertical support column, and the vertical lifting screw rod is screwed in the screw connection hole, and the top end of the vertical lifting screw rod extends out of the top surface of the vertical support column.

[0009] A locking nut is threadedly connected to the upper portion of the vertical lifting screw rod, and the bottom surface of the locking nut is pressed against the top surface of the vertical supporting column.

[0010] A C-shaped connecting kit is fixed on the middle outer wall of the vertical support column, a vertically extending through slot is formed on one side wall of the connecting kit, arc-shaped slots are formed in the middle of the left and right side walls of the through slot, the top surface of the arc-shaped slot extends out of the top surface of the connecting kit, and the front and rear of the arc-shaped baffle are inserted into the corresponding arc-shaped slots and basically cover the through slot.

[0011] A mounting groove is formed on one side wall of the arc-shaped slot, the permanent magnet block is nested in the mounting groove and fixed on the connecting kit, and the corresponding side walls of the front and rear of the arc-shaped baffle are tightly attached to the inner side walls of the corresponding arc-shaped slot and adsorbed with the corresponding permanent magnet block.

[0012] An upper horizontal arc portion is fixed to the top surface of the arc-shaped baffle, and the bottom surface of the upper horizontal arc portion is pressed against the top end surface of the connecting sleeve.

[0013] After the arc-shaped baffle is removed, the electrical connection line of the proximity switch can be extended from the through slot into the connection kit, and then the arc-shaped baffle is installed to achieve fixation, and the disassembly and assembly is convenient.

[0014] The outstanding effects of the utility model are:

[0015] Compared with the existing technology, its upper horizontal support plate can be adjusted in height to meet the needs of operators with different heights. After the wheel hub is placed, its proximity switch will sense the wheel hub and transmit the signal to the control host.

[0019] Figure 4 It is a simple distribution diagram between the utility model and the first machining center, the second machining center and the six-axis robot. Specific implementation method:

[0020] For example, see Figures 1 to 4 As shown, a hub processing turntable device includes a vertical support column 10, a fixing plate 11 at the bottom end of the vertical support column 10 is fixed on the ground, a plurality of vertical ribs are fixed on the top surface of the edge of the fixing plate 11, and the inner side wall of the vertical rib is welded and fixed to the lower outer side wall of the vertical support column 10. In this embodiment, a six-axis robot 100 is fixed on one side of the vertical support column 10 for grasping and picking up materials, and a first machining center 200 and a second machining center 300 are respectively fixed on the left and rear of the vertical support column 10;

[0021] In this embodiment, a vertical lifting screw 12 is installed on the vertical support column 10, a horizontal fixing plate 13 is fixed to the top of the vertical lifting screw 12, a proximity switch 1 is fixed to the top surface of the edge of the horizontal fixing plate 13, and an upper horizontal support plate 20 that can be adjusted up and down is installed above the horizontal fixing plate 13, and the bottom surface of the upper horizontal support plate 20 is close to the sensing end of the top of the proximity switch 1.

[0022] A screw hole extending vertically downward is formed in the middle of the top surface of the vertical support column 10 , and a vertical lifting screw rod 12 is screwed in the screw hole, and the top end of the vertical lifting screw rod 12 extends out of the top surface of the vertical support column 10 .

[0023] The upper portion of the vertical lifting screw rod 12 is threadedly connected with a locking nut 2 , and the bottom surface of the locking nut 2 is pressed against the top surface of the vertical support column 10 .

[0024] When in use, one only needs to loosen the locking nut 2 to rotate the vertical lifting screw 12, and adjust the height of the horizontal fixing plate 13 and the upper horizontal support plate 20 to meet the height requirements for placing the wheel hub. It is easy to adjust. After the adjustment is completed, it can be fixed by tightening the locking nut 2. It is easy to adjust.

[0025] Two connecting parts are fixed on the middle outer wall of the vertical support column 10, and the same C-shaped connecting kit 30 is fixed on the two connecting parts. A vertically extending through groove 31 is formed on one side wall of the connecting kit 30, and arc-shaped slots 32 are formed in the middle of the left and right side walls of the through groove 31. The top surface of the arc-shaped slot 32 extends out of the top surface of the connecting kit 30, and the front and rear parts of the arc-shaped baffle 33 are inserted into the corresponding arc-shaped slots 32 and basically cover the through groove 31.

[0026] A mounting groove is formed on one side wall of the arc-shaped slot 32, the permanent magnet block 3 is nested in the mounting groove and fixed on the connecting kit 30, and the corresponding side walls of the front and rear of the arc-shaped baffle 33 are tightly attached to the inner side walls of the corresponding arc-shaped slot 32 and adsorbed with the corresponding permanent magnet block 3.

[0027] An upper horizontal arc portion 34 is fixed to the top surface of the arc baffle 33 , and the bottom surface of the upper horizontal arc portion 34 is pressed against the top end surface of the connecting sleeve 30 .

[0028] When the above structure is in use, it is only necessary to move the arc baffle 33 upwards to separate the permanent magnet block 3 from the arc baffle 33, and then the corresponding operation can be performed.

[0029] Further, a limiting sleeve 40 is fixed to the middle of the top surface of the horizontal fixing plate 13, and the top surface of the limiting sleeve 40 is fixedly connected with an upper fixing plate 41 by bolts, and the upper fixing plate 41 covers the central vertical through hole of the limiting sleeve 40, and a central through hole with an inner diameter smaller than the inner diameter of the limiting sleeve 40 is formed in the middle of the upper fixing plate 41, and the central through hole is communicated with the central vertical through hole of the limiting sleeve 40, and a vertical shaft 21 is fixed to the middle of the bottom surface of the upper horizontal support plate 20, and the vertical shaft 21 is inserted in the central vertical through hole and the limiting sleeve 40, and a limiting plate 211 with an outer diameter larger than the outer diameter of the vertical shaft 21 is fixed to the bottom end of the vertical shaft 21, and the outer wall of the limiting plate 211 is close to the inner wall of the limiting sleeve 40, and the outer diameter of the limiting plate 211 is larger than the inner diameter of the central through hole of the upper fixing plate 41;

[0030] The limit sleeve 40 is sleeved with a buffer spring 4 , the bottom end of the buffer spring 4 is pressed against the top surface of the horizontal fixing plate 13 , and the top end of the buffer spring 4 is pressed against the bottom surface of the upper horizontal support plate 20 .

[0031] A fixed sleeve 6 is fixed on the top surface of the horizontal fixed plate 13, and an internal thread is formed on the inner side wall of the fixed sleeve 6. An adjusting limit sleeve 7 is screwed on the internal thread. The limit sleeve 40 is inserted into the adjusting limit sleeve 7. The top of the adjusting limit sleeve 7 is higher than the top of the fixed sleeve 40. An anti-collision elastic layer 8 is fixed on the top surface of the adjusting limit sleeve 7. The top surface of the anti-collision elastic layer 8 is higher than the top surface of the sensing end of the top of the proximity switch 1, and the top surface of the upper fixed plate 41 is lower than the top surface of the anti-collision elastic layer 8.

[0032] This structure allows the height position of the limit sleeve 7 to be adjusted by rotating the limit sleeve 7, so that the top surface of the anti-collision elastic layer 8 fixed on the top surface of the limit sleeve 7 is higher than the top surface of the sensing end at the top of the proximity switch 1, and the top surface of the upper fixed plate 41 is lower than the top surface of the anti-collision elastic layer 8. When in use, when the upper horizontal support plate 20 descends, its bottom surface rests on the top surface of the anti-collision elastic layer 8 to achieve limiting without contacting the top of the proximity switch 1. At the same time, its bottom surface is close to the top surface of the sensing end at the top of the proximity switch 1 to achieve sensing.

[0033] When this embodiment is in use, it uses a six-axis robot to take out the wheel hub processed in the first machining center 200 (it can also be a CNC machine tool) and place it on the anti-collision plate fixed on the top surface of the upper horizontal support plate 20. At this time, due to the weight of the wheel hub, the upper horizontal support plate 20 drops, and the buffer spring 4 is compressed, so that the bottom surface of the upper horizontal support plate 20 is close to the sensing end of the top of the proximity switch 1, but its bottom surface is pressed against the top surface of the anti-collision elastic layer 8, thereby achieving restriction and preventing the top surface of the sensing end of the top of the proximity switch 1 from colliding with the bottom surface of the upper horizontal support plate 20, thereby ensuring normal detection and use.

[0034] When the proximity switch 1 senses the signal, it transmits the sensing signal to the control host, which is electrically connected to a lamp body and a speaker. After receiving the signal, the control host controls the lamp body to light up and the speaker to make a sound, indicating that a wheel hub is placed on the anti-collision plate of the upper horizontal support plate 20 at this time, and manual cleaning is required to remove the debris on its surface.

[0035] After the manual operation is completed, generally the manual operation only takes 5 to 10 seconds (the time from placing the six-axis robot 100 on the upper horizontal support plate 20 to removing the wheel hub on the upper horizontal support plate 20 is set to 30 to 60 seconds), the six-axis robot 100 automatically grabs, and after grabbing, there is no wheel hub on the anti-collision plate of the upper horizontal support plate 20. Through the elastic recovery of the buffer spring 4, the upper horizontal support plate 20 is lifted, so that the proximity switch 1 cannot sense it. At this time, the control host receives a signal that the proximity switch 1 does not sense it, indicating that there is no wheel hub at this time. The control host (which is a conventional structure and will not be described in detail here) controls the corresponding lamp body to stop lighting and the speaker to stop sounding, which is very convenient.

[0036] The wheel hub taken away by the six-axis robot 100 can be placed in the second machining center 300 (which can also be a CNC machine tool) for subsequent processing. After the processing is completed, it can be directly placed on the ground or on the corresponding output mechanism after being grasped by the six-axis robot 100 to output the wheel hub. Since the output mechanism is a conventional structure, it will not be described in detail here and is not shown in the drawings.

[0037] The embodiment is easy to operate and has good use effect, and will not cause any missing wheel hubs or waste cuttings due to air blowing, thereby ensuring the processing quality of the wheel hubs.

[0038] At the same time, when this embodiment is in use, it can insert the electrical connection line of the proximity switch 1 into the connection kit 30 to achieve position limiting and prevent shaking.

[0039] When placing it, you only need to pull the arc baffle 33 upwards to pull it out of the two arc slots 32. At this time, the electrical connection line of the proximity switch 1 can be inserted from the through slot 31 into the connection kit 30, and then the front and rear parts of the arc baffle 33 are inserted into the two arc slots 32 and basically cover the through slot 31, and are fixed by adsorption through the permanent magnet block 3 to achieve the restriction of the electrical connection line of the proximity switch 1, so that it is not easy to shake, reduce the chance of breakage, and ensure normal use.
