Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a pipe column component milling fixture. Background Art

[0002] A fixture is a device used to clamp workpieces quickly, conveniently and safely. When a cylindrical workpiece needs to be milled, drilled, slotted and other processing operations on its end face and cylindrical surface by a milling machine, the axis of the cylindrical workpiece is usually used as the process reference.

[0003] After the traditional fixture clamps the workpiece, it is centered using the tool setting device of the milling machine. In order to improve processing efficiency, the traditional fixture mainly consists of a fixed clamp block and a movable push block to clamp the workpiece, wherein the fixed clamp block is V-shaped on one side facing the movable clamp block. When the movable push block pushes the workpiece toward the fixed clamp block, the V-surface of the fixed clamp block can be used to calibrate the center of the tubular workpiece, thereby preventing the center of the workpiece from shifting when the milling machine tool processes the workpiece. Although this fixture can realize automatic centering of the workpiece during clamping, it is limited by the opening distance on both sides of the V-surface of the clamp block, so that the clamp block can only clamp workpieces within a fixed specification. When a larger tubular component needs to be processed, a set of fixtures needs to be made.

[0004] Therefore, a pipe string component milling fixture is needed, which can be suitable for processing pipe string components within a larger diameter specification range. Utility Model Content

[0005] In order to solve the above technical problems, a pipe column component milling clamp is provided, which solves the problem in the prior art that the V-surface of the clamp cannot clamp pipe column components with larger diameter specifications.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a pipe column assembly milling fixture, including a base and a toad clamp slidably arranged on one side of the top surface of the base, the toad clamp top surface is provided with a screw rod 2, one side of the top surface of the base is provided with a T-shaped slide groove 2, the screw rod 2 passes through the toad clamp and penetrates into the T-shaped slide groove 2, the end of the screw rod 2 located in the T-shaped slide groove 2 is threadedly connected with a sliding block 2, the sliding block 2 is slidably connected in the T-shaped slide groove 2, and is characterized in that: a fixed clamping block is arranged on the other side of the top surface of the base;

[0007] The fixed clamp block is composed of two clamp blocks in the shape of right-angle trapezoids, the inclined surface of the clamp block faces the toad clamp, and a power component is arranged between the two clamp blocks;

[0008] The power component comprises a double-sided screw laterally arranged between the two clamping blocks, both ends of the double-sided screw respectively threadedly penetrate the two clamping blocks, a rotating rod is arranged on one side of the clamping block, and the rotating rod is fixedly penetrated through the double-sided screw.

[0009] Preferably, a screw rod is provided on the top surface of the clamping block, and a T-shaped groove is provided on the other side of the top surface of the base. The screw rod passes through the clamping block and enters the T-shaped groove. The end of the screw rod located in the T-shaped groove is threadedly connected to a sliding block, and the sliding block is slidably connected in the T-shaped groove.

[0010] Preferably, a shielding cover fixed to the top surface of the base is provided on the outer periphery of the double-sided screw, the shielding cover is in the shape of a porch, the shielding cover is located between the two clamping blocks, and the two clamping blocks have rectangular grooves matching the two sides of the shielding cover on one side facing the shielding cover.

[0011] Preferably, limiting blocks are rotatably sleeved on both sides of the shaft of the rotating rod, and the two limiting blocks are respectively fixed on both sides of the base.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] (1) Through the setting of the power component, when the rotating rod drives the double-sided screws to rotate synchronously, the two clamps are driven but restricted by the top surface of the base, causing the two clamps to move away from each other along the double-sided screws. The workpiece is placed between the inclined surfaces of the two clamps, and the toad clamp is moved until it contacts the workpiece. Then, screw 2 is tightened, and finally, the toad clamp is started to push the workpiece until it is against the inclined surface of the clamp, thereby fixing the workpiece between the inclined surfaces of the two clamps. In this way, the problem that the clamp in the prior art cannot clamp tubular workpieces with larger diameters can be solved.

[0014] (2) By setting the shielding cover, when the double-sided screw drives the two clamping blocks to unfold on the base, the exposed part of the double-sided screw rod between the two clamping blocks is covered by the shielding cover. In this way, during the processing of the workpiece, the flying debris is blocked by the shielding cover, preventing the double-sided screw rod from being stuck with debris.

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Reference Figure 1 , Figure 2 and Figure 3 As shown, a pipe column assembly milling fixture comprises a base 1, a toad clamp 2 slidably arranged on one side of the top surface of the base 1, and a fixed clamping block arranged on the other side of the top surface of the base 1, a screw rod 13 is arranged on the top surface of the toad clamp 2, a T-shaped slide groove 8 is opened on one side of the top surface of the base 1, the screw rod 13 passes through the toad clamp 2 and penetrates into the T-shaped slide groove 8, the end of the screw rod 13 located in the T-shaped slide groove 8 is threadedly connected with a sliding block 7, and the sliding block 7 is slidably connected in the T-shaped slide groove 8;

[0022] The fixed clamp block is composed of two clamp blocks 3 in the shape of right-angle trapezoids and distributed in mirror image, the inclined surface of the clamp block 3 faces the toad clamp 2, and a power component is arranged between the two clamp blocks 3;

[0023] The power component includes a double-sided screw rod 4 transversely arranged between two clamping blocks 3, both ends of the double-sided screw rod 4 are threaded through the two clamping blocks 3, a rotating rod 9 is arranged on one side of the clamping block 3, the rotating rod 9 is fixedly passed through the double-sided screw rod 4, and both sides of the rod body of the rotating rod 9 are rotatably sleeved with limiting blocks 11, and the two limiting blocks 11 are respectively fixed on both sides of the base 1;

[0024] When the workpiece is to be clamped, the two sides of the double-sided screw 4 can be driven to rotate synchronously by rotating the rotating rod 9. At this time, the two clamping blocks 3 are driven but are restricted by the top surface of the base 1, causing the two clamping blocks 3 to move away from each other along the double-sided screw 4. After adjusting the appropriate spacing between the two clamping blocks 3 according to the workpiece, the workpiece is placed between the inclined surfaces of the two clamping blocks 3. Subsequently, the screw 2 13 is loosened from the sliding block 2 7, and the toad clamp 2 is moved to contact the workpiece. Subsequently, the screw 2 13 is tightened. During this process, the sliding block 2 7 rises along the rod body of the screw 2 13 until it is against the top surface of the inner wall of the T-shaped slide groove 2 8. Subsequently, the toad clamp 2 is locked in the specified position through the screw 2 13 and the sliding block 2 7. Finally, the toad clamp 2 is started to push the workpiece until it is against the inclined surface of the clamping block 3, thereby fixing the workpiece between the inclined surfaces of the two clamping blocks 3. In this way, the problem that the clamp in the prior art cannot clamp a tubular workpiece with a larger diameter can be solved.

[0025] Further, refer to Figures 1 to 3 It is worth noting that a screw rod 12 is provided on the top surface of the clamping block 3, and a T-shaped slide groove 6 is provided on the other side of the top surface of the base 1. The screw rod 12 penetrates the clamping block 3 and enters the T-shaped slide groove 6. The end of the screw rod 12 located in the T-shaped slide groove 6 is threadedly connected with a sliding block 10, and the sliding block 10 is slidably connected in the T-shaped slide groove 6.

[0026] Through the setting of the sliding block 10 and the screw rod 12, when the two clamping blocks 3 need to be unfolded, the screw rod 12 is first loosened from the sliding block 10, and then the two clamping blocks 3 are moved by the double-sided screw rod 4, and then the screw rod 12 is tightened from the sliding block 10. During this process, the sliding block 10 rises along the rod body of the screw rod 12 until it is against the top surface of the inner wall of the T-shaped slide groove 6, and then the clamping block 3 is firmly fixed on the top surface of the base 1 through the screw rod 12 and the sliding block 10.

[0027] It was found in subsequent use that when clamping a tubular workpiece with a larger diameter for processing, the rod body of the double-sided screw 4 was exposed after the double-sided screw 4 separated the two clamping blocks 3, and the debris splashed during the milling of the workpiece was stuck between the threads of the rod body of the double-sided screw 4, resulting in the debris damaging the threads of the double-sided screw 4 and the clamping block 3 when the double-sided screw 4 was subsequently used to close the clamping block 3.

[0028] In view of this, in order to solve the above problems, refer to Figures 1 to 3 As shown, it is worth mentioning that a shielding cover 5 fixed to the top surface of the base 1 is provided on the outer periphery of the double-sided screw 4, and the shielding cover 5 is in the shape of a porch. The shielding cover 5 is located between two clamping blocks 3, and the two clamping blocks 3 have rectangular grooves matching the two sides of the shielding cover 5 on one side facing the shielding cover 5.

[0029] By setting the shielding cover 5, when the double-sided screw 4 drives the two clamping blocks 3 to unfold on the base 1, the exposed part of the rod of the double-sided screw 4 between the two clamping blocks 3 is covered by the shielding cover 5. In this way, during the processing of the workpiece, the flying debris is blocked by the shielding cover 5, preventing the double-sided screw 4 from being stuck with debris.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
