Description

Technical Field

[0001] This utility model relates to a support structure for processing equipment, specifically a positioning support structure for shaft-type workpieces. Background Technology

[0002] During machining, shaft-type workpieces require stable support on the equipment to ensure good machining stability. Existing support structures merely provide simple multi-point support for the shaft-type workpiece without considering its center of gravity distribution. This can lead to instability during machining, or excessive redundant support resulting in wasted costs and difficulties in positioning and adjustment. Furthermore, existing support structures have poor adjustability and cannot adapt to various machining environments. Utility Model Content

[0003] The present invention aims to provide a positioning support structure for shaft-type workpieces that has good support effect, simplified structure and strong adaptability.

[0004] This solution provides a positioning and support structure for shaft-type workpieces, including a base plate. A first support, a second support, and a positioning and clamping device are sequentially fixed on the base plate. The first and second supports are used to support the shaft body of the shaft-type workpiece, and the center of gravity of the shaft-type workpiece is located between the first and second supports. Both the first and second supports include a support base, the bottom of which is fixed to the base plate. The top of the support base is a V-shaped groove, and a support pin is respectively provided on the two inclined surfaces of the V-shaped groove.

[0005] The first support and the second support can stably support the workpiece. After the machining position of the shaft workpiece is determined, the positioning and clamping device is used to fix the radial position of the workpiece. The support pins in the V-groove are used for fine adjustment of the workpiece position so as to align with the positioning center of the machining. By installing support pins of different sizes, it can adapt to workpieces of different sizes.

[0006] Furthermore, both the first and second supports are equipped with auxiliary V-shaped brackets. These auxiliary V-shaped brackets are used for auxiliary support.

[0007] Furthermore, the auxiliary V-shaped bracket is detachably mounted on the support bases of the first support and the second support. The auxiliary V-shaped bracket, through its detachable mounting structure, allows for replacement with different sizes or adjustment of its position.

[0008] Furthermore, the auxiliary V-shaped bracket includes a connecting plate and a V-shaped support portion. The connecting plate is connected to the support base via bolts installed in the slotted holes, and the V-shaped support portion is located at the top of the connecting plate. The auxiliary V-shaped bracket can be adjusted in position via the slotted holes on the connecting plate, which not only strengthens the support but also allows for adjustment to accommodate changes in the center position.

[0009] Furthermore, the second support frame is also equipped with a workpiece detection device, which includes a detection device housing, a detection rod, and a pneumatic plug. The upper part of the detection device housing is connected to an air inlet pipe, and the lower part is connected to an air outlet pipe. The pneumatic plug is slidably disposed within the cavity of the detection device housing. One end of the detection rod is fixedly connected to the pneumatic plug, and the other end is the detection part outside the detection device housing. An electronic induction magnetic switch is respectively provided on the upper and lower parts of the detection device housing, and a magnet is provided on the pneumatic plug. The electronic induction magnetic switch is connected to the central control electrical equipment to identify whether a workpiece is loaded, so as to start the subsequent processing procedure.

[0010] Furthermore, the positioning and clamping device includes a clamping base, an adjusting seat, and a pneumatic clamping device. The clamping base is disposed on the base plate, the adjusting seat is detachably and fixedly disposed on the clamping base, and the pneumatic clamping device is fixedly disposed on the adjusting seat.

[0011] Furthermore, an adjusting block is fixedly provided on the clamping base on one side of the adjusting seat, and an adjusting shim is detachably provided on the adjusting block. The adjusting shim abuts against the bottom side of the adjusting seat. The size of the adjusting shim can be replaced. By replacing the adjusting shim with different sizes, the lateral position of the adjusting seat can be adjusted to facilitate machining center calibration.

[0012] Furthermore, the support pin is mounted on the inclined surface of the V-shaped groove via a base, and the bottom of the base is detachably connected to the V-shaped groove via threads. The support pin is fixedly mounted on the top of the base. This structural design allows for easy removal of the base along with the support pin, facilitating the replacement of support pins of different sizes.

[0013] The advantages of this utility model are: by adopting the workpiece positioning support structure of this solution, the center of gravity of the shaft workpiece is placed between the first support and the second support. This not only provides stable support, but also simplifies the support structure, avoids excessive redundant support leading to cost waste, simplifies the positioning adjustment operation, and can be adjusted to adapt to different working conditions.

The first support 200 and the second support 300 are used to support the shaft body of the shaft-type workpiece, and the center of gravity of the shaft-type workpiece is located between the first support 200 and the second support 300. Both the first support 200 and the second support 300 include a support base 1, the bottom of which is bolted to the base plate 100. The top of the support base 1 is a V-shaped groove 2, and a support nail 3 is respectively provided on the two inclined surfaces of the V-shaped groove 2.

[0025] See details Figure 2 In this embodiment, the support pin 3 is installed on the inclined surface of the V-shaped groove 2 via the base 6. The bottom of the base 6 is detachably connected to the V-shaped groove 2 via threads, and the support pin 3 is fixedly mounted on the top of the base 6. This structural design allows for easy replacement of support pins 3 of different sizes by disassembling the base 6 together with it.

[0026] The first support 200 and the second support 300 can stably support the workpiece. After the machining position of the shaft workpiece is determined, the positioning and clamping device 400 is used to fix the radial position of the workpiece. The support pin 3 is set in the V-shaped groove 2 for fine adjustment of the workpiece position so as to align with the positioning center of the machining. By installing support pins 3 of different sizes, it can adapt to workpieces of different sizes.

[0027] The first support 200 and the second support 300 are also respectively provided with auxiliary V-shaped brackets 4. The auxiliary V-shaped brackets 4 are used for auxiliary support. The auxiliary V-shaped brackets 4 are detachably installed on the support bases 1 of the first support 200 and the second support 300. The auxiliary V-shaped brackets 4 can be replaced with different sizes or adjusted in position due to their detachable installation structure.

[0028] In this embodiment, the auxiliary V-shaped bracket 4 includes a connecting plate 41 and a V-shaped support part 42. The connecting plate 41 is connected to the support base 1 through bolts installed in the slotted hole, and the V-shaped support part 42 is located at the top of the connecting plate 41. The auxiliary V-shaped bracket 4 can be adjusted in position through the slotted hole on the connecting plate 41, which not only strengthens the support but also allows for adjustment to accommodate changes in the center position.

[0029] The second support frame is also equipped with a workpiece inspection device 5, as detailed below. Figure 4 The workpiece inspection device 5 includes an inspection device housing 51, an inspection rod 52, and a pressure plug 43.
