Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, and in particular to a clamping tooling and a drilling and tapping machine. Background Technology

[0002] In the field of machining, precise workpiece clamping is a fundamental step in ensuring machining quality. Traditional clamping methods typically rely on manual operation of appropriate tooling fixtures, combined with manual tightening of bolts, pressure plates, and other components to position and fix the workpiece. This method requires operators to repeatedly adjust the tooling position, align the workpiece, and tighten bolts one by one, resulting in significant inefficiency. Especially in scenarios requiring high-volume continuous processing, the pace of manual operation is difficult to match the high-efficiency operation requirements of automated equipment, slowing down the overall production cycle and becoming a bottleneck restricting the large-scale application of automated production lines.

[0003] For highly integrated equipment such as modern CNC machining centers, the inefficiency of traditional manual clamping methods not only increases labor costs, but also provides a clamping fixture and drilling and tapping machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a clamping fixture and a drilling and tapping machine.

[0009] A clamping cylinder is mounted on the mounting bracket, the clamping cylinder is located in the clearance groove, and the clamping cylinder has two clamping ends;

[0010] The clamping blocks are fixedly installed on the two clamping ends of the clamping cylinder, and the clamping cylinder drives the clamping blocks on the two clamping ends to move closer to each other or further apart.

[0011] Preferably, a rotary drive component is also mounted on the bottom surface of the mounting frame, the rotating end of the rotary drive component extends above the mounting frame, and a rotary carrier plate is fixedly mounted on the rotating end of the rotary drive component.

[0018] This utility model has the following advantages:

[0019] 1. This utility model uses a clamping cylinder to drive the clamping blocks on two clamping ends to move closer or further apart, thereby achieving automatic clamping and release of the workpiece and solving the problem of low efficiency caused by traditional manual tightening of bolts. The clamping cylinder is built into the clearance groove of the carrier, which is compact and space-saving, and is easy to integrate with drilling and tapping machines. The clamping blocks are directly fixed to the driving end of the clamping cylinder, and the bidirectional synchronous movement ensures the positioning accuracy of the workpiece and avoids manual adjustment errors.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0031] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figure 1 — Figure 8 The example shown.

[0033] See Figure 8 As shown, the workpiece is rectangular, and holes need to be made on two opposite sides of the workpiece. It should be noted that before the actual drilling, pilot holes need to be made at the locations to be drilled to prevent the drill bit from slipping during the actual drilling process and causing the hole position to shift.

[0034] See Figure 1 and Figure 2 As shown in the figure, this application provides a clamping fixture, which includes a mounting frame 100, a carrier frame 200, a clamping cylinder 300, and a clamping block 400.

[0035] Specifically, the carrier 200 is mounted on the mounting frame 100, the carrier 200 has a clearance groove 210, the clamping cylinder 300 is mounted on the mounting frame 100, the clamping cylinder 300 is located in the clearance groove 210, and the clamping cylinder 300 has two clamping ends. The clamping blocks 400 are respectively fixedly mounted on the two clamping ends of the clamping cylinder 300, and the clamping cylinder 300 drives the clamping blocks 400 on the two clamping ends to move closer to or further away from each other.

[0036] Please see Figure 1 and Figure 2 As shown, the workpiece is supported by the carrier 200, that is, the workpiece is placed on the carrier 200. At this time, the workpiece is located between two clamping blocks 400. Then, the clamping cylinder 300 drives the clamping blocks 400 on its two clamping ends to move closer to each other, thereby realizing the clamping and fixing of the workpiece located on the carrier 200, and completing the automatic clamping of the workpiece.

[0037] Compared with the existing method of manual clamping, the technical solution disclosed in this application can automatically fix and clamp the product located on the carrier 200, thereby greatly improving the clamping efficiency.

[0038] Please see Figure 1 , Figure 2 as well as Figure 3 As shown, the clamping cylinder 300 is a cylinder with two moving ends. The clamping cylinder 300 drives the clamping blocks 400 on the two moving ends to move closer to each other or away from each other, thereby achieving the clamping and easing of the workpiece. It can be understood that the clamping cylinder 300 can also be composed of two unidirectional drive cylinders, that is, a common unidirectional linear drive cylinder is installed on each side of the carrier 200. The two unidirectional linear drive cylinders drive the corresponding clamping blocks 400 to move toward or away from the carrier 200, thereby also achieving the clamping and easing of the workpiece. In practice, other structures can also be used to achieve the clamping of the workpiece, which is not limited here.

[0039] In this embodiment, the carrier 200 is U-shaped.

[0040] The bottom surface of the mounting bracket 100 is also equipped with a rotary drive component 500. The rotating end of the rotary drive component 500 extends above the mounting bracket 100. The rotating end of the rotary drive component 500 is fixedly mounted with a rotary carrier plate 510. The carrier 200 and the clamping cylinder 300 are both fixedly mounted on the rotary carrier plate 510.

[0041] Please continue reading. Figure 1 and Figure 2As shown, before drilling, a pilot hole needs to be drilled at the corresponding position of the workpiece to prevent the drill bit from shifting position and causing the drilled hole to also shift. Therefore, after drilling the pilot hole, it needs to be rotated 180 degrees to align the pilot hole with the drilling machine, and the drilling machine will drill at the position of the pilot hole. Therefore, this application needs to install a rotary drive 500 on the mounting frame 100 to drive the workpiece held by the two clamping blocks 400 to rotate.

[0042] Specifically, the rotary drive 500 is fixedly installed on the bottom surface of the mounting bracket 100, and the rotating end of the rotary drive 500 extends above the mounting bracket 100. The rotary carrier plate 510 is fixedly installed on the rotating end of the rotary drive 500, and the rotary carrier plate 510 is used to fix the carrier 200 and the clamping cylinder 300, so that the carrier 200 and the clamping cylinder 300 are driven to rotate together with the rotary carrier plate 510 by the rotary drive 500. In this embodiment, the clearance groove 210 is formed by the carrier 200 and the rotary carrier plate 510.

[0043] For example, the rotary drive component 500 can be selected as a rotary cylinder, motor, servo motor or other rotary drive device. In order to improve the accuracy of the rotary drive component 500 driving the rotary carrier plate 510 to rotate, the rotary drive component 500 can be selected as a servo motor. It should be noted that in practice, other components and devices can be selected according to the requirements of rotation accuracy, and no specific limitation is made here.

[0044] A bracket 110 is provided on the upper surface of the mounting frame 100 on one side of the carrier 200, and a positioning and pushing component 600 is installed on the bracket 110.

[0045] Please see Figure 1 , Figure 2 as well as Figure 7 As shown, during the loading process, in order to determine whether the workpiece has reached the predetermined position, the positioning and pushing component 600 blocks the workpiece, thereby limiting the loading of the workpiece and ensuring that it reaches the predetermined position. After the workpiece is processed, the positioning and pushing component 600 can push the processed workpiece from the carrier 200 to the unloading position, thereby realizing automatic unloading.

[0046] The positioning and pushing assembly 600 includes a positioning and pushing cylinder 610, and an abutment block 620 is installed on the driving end of the positioning and pushing cylinder 610.

[0047] Please continue reading. Figure 1 , Figure 2 as well as Figure 7As shown, when it is necessary to position the workpiece being loaded, the positioning and pushing cylinder 610 first drives the abutment block 620 to move towards the carrier 200, and moves the abutment block 620 to a predetermined position. When the workpiece is loaded, it will abut against the abutment block 620, thus indicating that the workpiece has been loaded to the predetermined position. Afterwards, the positioning and pushing cylinder 610 can drive the abutment block 620 to return to its initial state, preventing motion interference between the rotating drive 500 and the carrier 200, clamping cylinder 300, and clamping block 400 when they rotate. Furthermore, after the workpiece is drilled, the clamping cylinder 300 drives the clamping block 400 to release the clamped workpiece. The positioning and pushing cylinder 610 can then drive the abutment block 620 to move towards the carrier 200 again, thereby pushing the finished workpiece out of the carrier 200 to complete the rotation and unloading. When positioning and clamping the next workpiece, the above actions can be repeated in a cycle.

[0048] See Figure 5 and Figure 6 As shown, one side of the clamping block 400 is provided with a protrusion 410. In order to improve the clamping force on the workpiece between the two clamping blocks 400 and prevent it from tilting during drilling, the protrusions 410 are evenly distributed on the sides of the two clamping blocks 400 facing each other, thereby improving the clamping force on the workpiece and maintaining its stability during processing.

[0049] Please continue reading. Figure 5 and Figure 6 As shown, at least one clearance hole 420 is provided through the side of the clamping block 400. Since the thickness of the workpiece being clamped may be small, in order to drill the side of the relatively thin workpiece, the clearance hole 420 is provided on the side of the clamping block 400 so that the drill bit can pass through the clearance hole 420 to clamp the workpiece, thereby realizing the drilling of workpieces of different thicknesses.

[0050] Furthermore, the clamping block 400 can be detachably connected to the clamping end of the clamping cylinder 300. Specifically, a bolt connection can be used to achieve the detachable connection, thereby enabling the clamping of different types of workpieces.

[0051] The working process of this utility model is as follows: Taking the case where a pilot hole needs to be drilled before the main hole is drilled, the following example illustrates the process. First, the positioning and pushing cylinder 610 moves the abutment block 620 to a predetermined position at the carrier 200, thereby limiting and blocking the workpiece. If the workpiece touches the abutment block 620 during loading, it indicates that the workpiece has reached the predetermined position. At this time, the clamping cylinder 300 moves the two clamping blocks 400 closer together to clamp the workpiece. Next, the positioning and pushing cylinder 610 moves the abutment block 620 back to its initial position. After positioning, the workpiece is pre-drilled using a drilling machine on one side, i.e., a pilot hole is drilled. After the pilot hole is drilled, the workpiece is rotated by a rotary drive 500 so that the pilot hole is aligned with the position of the drilling machine on the other side. The drilling machine on the other side drills the hole at the pilot hole position, thus completing the drilling process. Next, the clamping cylinder 300 drives the two clamping blocks 400 to move away from each other and release the clamping of the processed workpiece. Then, the positioning and pushing cylinder 610 drives the abutment block 620 to move and push the processed workpiece on the carrier 200 to unload it.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
