Description

Technical Field

[0001] This utility model belongs to the field of workpiece processing technology, specifically relating to a high-efficiency positioning fixture for irregularly shaped products. Background Technology

[0002] In the processing of irregularly shaped workpieces, the irregular shape of the workpiece makes it difficult to clamp and position it. In addition, if there is no suitable fixture, the workpiece may need to be clamped multiple times to meet the processing needs of different parts. Multiple clamping can easily cause deviations in the workpiece datum surface, which will reduce the accuracy of the processed workpiece and increase the processing cycle, thereby reducing the efficiency of workpiece production and increasing the workload. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency positioning fixture for irregularly shaped products, which can perform machining on multiple surfaces of the workpiece in a single clamping operation, and can clamp multiple workpieces at once, thereby improving product production efficiency.

[0004] The specific technical solution adopted in this utility model is as follows: A high-efficiency positioning fixture for irregularly shaped products includes a bed frame. A spindle box and a tail shaft mechanism are respectively installed at both ends of the upper part of the bed frame. A receiving plate is installed between the spindle box and the tail shaft mechanism. The receiving plate is provided with a plurality of positioning grooves that match the workpiece. The workpiece is placed in the positioning groove and is clamped and positioned by pressure bars. The pressure bars are installed in different areas depending on the processing position. When processing area one of the workpiece is processed, the pressure bars press on processing area two of the workpiece. When processing area two is processed, the pressure bars press on processing area one of the workpiece.

[0005] In a preferred embodiment, the two ends of the receiving plate are respectively fixed to the turntable of the main spindle box and the turntable of the tail shaft mechanism by bolts, and the receiving plate can be horizontally flipped.

[0006] In a preferred embodiment, the positioning groove is provided with holes that match the processing area.

[0007] In a preferred embodiment, threaded holes are respectively provided on the upper surfaces of both ends of the receiving plate.

[0008] In a preferred embodiment, the pressure strip is fixed to the receiving plate by screwing quick-release bolts into threaded holes.

[0009] The technical effects achieved by this utility model are as follows: This utility model allows for rapid positioning of a workpiece by creating positioning slots on the receiving plate that match the corresponding parts of the workpiece. Furthermore, by creating multiple positioning slots on the receiving plate, multiple workpieces can be clamped at once. Most importantly, depending on the processing of different areas, the pressure bar can be pressed onto different parts of the workpiece. When changing the position of the pressure bar, the relative position of the receiving plate and the workpiece remains unchanged, avoiding deviations that could affect the processing accuracy of the workpiece during repeated clamping.

[0016] Please see the appendix Figures 1 to 5 As shown, this utility model provides a high-efficiency positioning fixture for irregularly shaped products, including a bed frame 1. A spindle box 2 and a tail shaft mechanism 3 are respectively installed at both ends of the upper part of the bed frame 1. A receiving plate 4 is installed between the spindle box 2 and the tail shaft mechanism 3. The receiving plate 4 is provided with several positioning grooves 5 that match the workpiece 6. The workpiece 6 is placed in the positioning grooves 5 and clamped and positioned by pressure strips 7. The pressure strips 7 are installed in different areas depending on the processing position. When processing area 61 of the workpiece 6, the pressure strips 7... The pressure strip 7 is pressed on the processing area 62 of the workpiece 6. When processing the processing area 62, the pressure strip 7 is pressed on the processing area 61 of the workpiece 6. The two ends of the receiving plate 4 are fixedly installed on the turntable of the spindle box 2 and the turntable of the tail shaft mechanism 3 by bolts. The receiving plate 4 can be horizontally flipped. The positioning groove 5 is provided with holes 51 that match the processing area. The upper end faces of both ends of the receiving plate 4 are provided with threaded holes 41. The pressure strip 7 is fixed on the receiving plate 4 by screwing it into the threaded holes 41 with quick-release bolts 71.

[0017] When processing the product, the end of the blank that matches the positioning groove 5 is placed in the positioning groove 5. Then, depending on the area to be processed of the workpiece 6, the installation position of the pressure strip 7 is selected. The pressure strip 7 is fixed on the receiving plate 4 by quick-release bolts 71. Together with the positioning groove 5, the pressure strip 7 clamps and positions the workpiece 6. Then the product is processed. This utility model utilizes positioning grooves 5 on the receiving plate 4 that match the corresponding parts of the workpiece 6. After the workpiece 6 is placed in the positioning grooves 5, it can be quickly positioned. Furthermore, by creating several positioning grooves 5 on the receiving plate 4, multiple workpieces 6 can be clamped at once. In addition, and most importantly, the pressure strip 7 can be pressed onto different parts of the workpiece 6 according to the processing of different areas. Moreover, when changing the position of the pressure strip 7, the relative position between the receiving plate 4 and the workpiece 6 remains unchanged, avoiding deviations that could affect the processing accuracy of the workpiece 6 when clamping it multiple times. In this embodiment, the blank of workpiece 6 is a cast blank, such as... Figure 5 The processing area 61 shown contains burrs and excess material accumulation caused by uneven casting, while the processing area 62 is for drilling holes in the workpiece 6. In order to facilitate clamping, the processing of this product is carried out in the following order: first, the processing area 61 is processed, then the pressure strip 7 is replaced in the processing area 61, and then the processing area 62 is processed. This device uses a machining center to process workpiece 6, and can perform milling and other processing on the product; In this application, the receiving plate 4 is fixed to the turntable of the spindle box 2 and the turntable of the tail shaft mechanism 3 by bolts. The central axes of the turntable of the spindle box 2 and the turntable of the tail shaft mechanism 3 are coincident. The spindle box 2 has a power structure that can drive the receiving plate 4 to rotate horizontally along the central axis. This allows the workpiece 6 to be flipped and tilted during processing, which facilitates the machining center to process other planes of the workpiece 6. This further improves the device's ability to process more parts in one clamping operation. In this device, the machining center operates through the input programming program. The timing and angle of rotation of the spindle box 2 are programmed according to the size requirements of the workpiece 6 and input into the machining center for driving through the program. These are all existing technologies and are not the focus of this improvement. Therefore, they will not be elaborated further.
