Description

Technical Field

[0001] The utility model relates to a fixed tool for combined processing of two semicircular workpieces. Background Art

[0002] Existing shaft clamps and bushing parts such as Figure 6 and Figure 7 As shown, the workpiece 20 is composed of two semicircular workpieces 200, and the semicircular workpieces 200 are formed by casting. Since the axial hole 230 in the workpiece 200 needs to cooperate with the shaft. Therefore, after casting, the axial hole 230 of the workpiece 20 needs to be processed to ensure the accuracy and coaxiality of the axial hole 230 formed by the combination of the two semicircular workpieces 200. However, during machining, how to accurately and quickly fix and clamp the two semicircular workpieces 200 becomes a problem to be considered before machining. For this reason, a fixed tooling for combined processing of two semicircular workpieces is urgently needed to solve the clamping problem of the existing combined processing of two semicircular workpieces. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a fixed tooling for combined processing of two semicircular workpieces.

The left and right sides of the base are respectively connected with limiting bolts, and the limiting bolts pass through the ear seat holes of the workpiece and the positioning sleeves and are threadedly connected to the base in sequence, and the bolt head of the limiting bolt fits on the ear seat of the workpiece.

[0005] Preferably, a clamping assembly is detachably connected to the base and cooperates with the base to clamp the workpiece up and down.

[0006] Preferably, the clamping assembly includes a pressure plate affixed to the upper surface of the workpiece, the pressure plate is provided with a through hole, a locking bolt is passed through the through hole, the locking bolt is threadedly connected to the base, and the bolt of the locking bolt is affixed to the upper surface of the pressure plate.

[0007] Preferably, the clamping assembly comprises a mounting seat fixedly arranged on the base, a tightening bolt is threadedly connected to the mounting seat, and the left and right tightening bolts are clamped on the side wall of the workpiece.

[0008] Compared with the prior art, the utility model includes a base, and the base is provided with clamping assemblies for clamping workpieces at the front and rear, respectively. The left and right sides of the base are provided with positioning sleeves for inserting and positioning with the positioning convex ring of the workpiece. The base is connected with limit bolts at the left and right sides, respectively. The limit bolts pass through the ear seat holes of the workpiece and the positioning sleeves and are threadedly connected with the base in sequence, and the bolt heads of the limit bolts fit on the ear seats of the workpiece. The front and rear clamping assemblies and the left and right positioning sleeves cooperate with the positioning convex ring to effectively constrain the left and right and front and back positions of the two semicircular workpieces.

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] See also Figure 1-Figure 5A fixed tooling for combined processing of two semicircular workpieces includes a base 10, on which clamping assemblies 30 for clamping a workpiece 20 are respectively arranged at the front and rear, and positioning sleeves 40 for inserting and positioning with a positioning convex ring 220 of the workpiece 20 are arranged on the left and right sides of the base 10, and the base 10 is respectively connected with limiting bolts 60 on the left and right sides, and the limiting bolts 60 pass through the ear seat holes 210 of the workpiece 20 and the positioning sleeves 40 and are threadedly connected to the base 10 in sequence, and the bolt heads of the limiting bolts 60 are affixed to the ear seats 240 of the workpiece 20.

[0018] In the above embodiment, what is to be achieved is to process the axial hole 230 of the workpiece 20. In this state, the front and rear clamping components and the cooperation of the left and right positioning sleeves and the positioning convex ring can effectively constrain the left and right and front and back positions of the two semicircular workpieces. At the same time, the plug-in cooperation of the positioning sleeve and the positioning convex ring can constrain the two semicircular workpieces from being separated, playing the role of constraining the two to be in a combined state. Under the action of the limit bolt, it can constrain the workpiece from moving up and down, thereby achieving complete constraint of the workpiece composed of the two semicircular workpieces, so that it will not move relative to the base, so as to facilitate machining.

[0019] See also Figures 1 to 3 The base 10 is detachably connected with a clamping assembly 50 that cooperates with the base 10 to clamp the workpiece 20 up and down. The clamping assembly 50 includes a pressing plate 510 that fits on the upper surface of the workpiece 20. The pressing plate 510 is provided with a through hole 511. A locking bolt 520 is inserted into the through hole 511. The locking bolt 520 is threadedly connected to the base 10, and the bolt of the locking bolt 520 fits on the upper surface of the pressing plate 510. In this embodiment, the clamping assembly 50 is used to replace the limit bolt 60. The limit bolt 60 can be removed by constraining the upper and lower positions of the workpiece 20 through the clamping assembly 50, so as to facilitate machining of the ear seat hole 210. In addition, due to the setting of the positioning sleeve 40, during machining, the head end of the tool can be inserted into the positioning sleeve 40 to achieve machining of the ear seat hole 210.

[0020] When the clamping assembly 50 is clamped, the pressing plate 510 is fitted to the upper surface of the workpiece 20, and then the locking bolt 520 is passed through the through hole 511 and the through hole 230 in sequence, and then threadedly connected to the base 10. Through the cooperation between the pressing plate 510 and the base 10, the upper and lower positions of the workpiece 20 can be effectively constrained.

[0021] See also Figure 1The clamping assembly 30 includes a mounting seat 310 fixedly mounted on the base 10, and a tightening bolt 320 is threadedly connected to the mounting seat 310. The two tightening bolts 320 are clamped on the side wall of the workpiece 20. By tightening or loosening the tightening bolts 320, when the tightening bolts 320 are turned, they can gradually approach or move away from the workpiece 20, so as to tighten the workpiece 20 from the front and rear sides to constrain the position of the workpiece 20, and at the same time prevent the two semicircular workpieces 200 that are assembled in a close relationship from each other.
