Description

Technical Field

[0001] This utility model relates to a tool clamping fixture, specifically a PCB tool clamping fixture for automotive parts processing, belonging to the field of tool clamping fixture technology. Background Technology

[0002] PCB, or Printed Circuit Board, is an important component of the electronics industry. In the PCB manufacturing process, cutting tools play a crucial role. PCB cutting tools, as the name suggests, are specialized tools used to process PCB boards. There are many types of PCB cutting tools, including but not limited to etching tools, drilling tools, and forming tools. Each tool has its specific function and application scenarios. With the development of the times and technology, PCB cutting tools have gradually been applied to various industries, such as the processing of automotive parts. Before processing, PCB cutting tools need to be fixed by mechanical clamping fixtures.

[0003] However, most existing machine clamping fixtures have various problems. For example, in the PCB board processing fixture disclosed in publication number CN210579540U, although double-sided welding can be completed in one loading, making double-sided welding of PCB boards easier to operate, most machine clamping fixtures still use screw locking to fix the PCB tool when clamping the tool. However, PCB tools often require multiple screws to be fully locked. Therefore, during operation, the screws often need to be manually tightened. Since there are multiple screws, tightening them requires a lot of time and effort, which seriously affects work efficiency. Moreover, the locking force of each screw cannot be precisely controlled, resulting in the tool being unstable and thus affecting the processing accuracy. Utility Model Content

[0004] This utility model addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the purpose of this utility model is to overcome the aforementioned shortcomings in existing technologies by proposing a PCB tool clamping fixture for automotive parts processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A PCB tool clamping fixture for automotive parts processing includes a fixed cylinder, a docking ring, a clamping mechanism, and a limiting mechanism. The fixed cylinder is fixed on the machine tool, and the docking ring is fixed at one end of the fixed cylinder.

[0007] The clamping mechanism for clamping and locking PCB cutting tools is connected inside the fixed cylinder, and the clamping mechanism includes a clamping plate, a rotating rod, a limiting ring, a linkage rod, and an adjusting rod. The rotating rod is fixed to one end of the clamping plate and is rotatably connected to the inner side of the mating ring. The limiting ring is coaxially fixed inside the fixed cylinder. The linkage rod is slidably connected inside the limiting ring. The tapered adjusting rod is coaxially fixed to one end of the linkage rod near the clamping plate, and one end of the clamping plate slides against the outer wall of the adjusting rod.

[0008] The limiting mechanism is located on the fixed cylinder at the end away from the clamping plate.

[0009] As a further embodiment of this utility model: the clamping mechanism further includes an abutment plate, a support base, a transmission rod, and a throttle handle. The abutment plate is coaxially fixed to the end of the linkage rod away from the adjusting rod. The support base is fixed to the side of the fixed cylinder near the abutment plate. The transmission rod is rotatably connected to the support base. One end of the throttle handle is fixed to the transmission rod, and the abutment plate slides against one side of the throttle handle. The limiting mechanism is provided on the support base.

[0010] As a further embodiment of this utility model: a roller is rotatably connected to one side of the throttle, and the roller abuts against the abutment plate.

[0011] As a further improvement of this utility model: a first return spring is sleeved on the linkage rod, one end of the first return spring abutting against the limiting ring and the other end abutting against the fixed cylinder.

[0012] As a further embodiment of this utility model: the limiting mechanism includes a ratchet, a pawl, and a second return spring. The ratchet is coaxially fixed on the transmission rod. One end of the pawl is rotatably connected to the side wall of the support seat, and the other end slides against the edge of the pawl. One end of the second return spring is connected to the pawl, and the other end is connected to the support seat.

[0013] As a further improvement of this utility model: the fixed cylinder is provided with an air guide pipe connection hole, and the air guide pipe connection hole communicates with the internal cavity of the fixed cylinder.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, by setting up a clamping mechanism, the PCB tool can move the adjusting rod through the sliding of the linkage rod in the clamping mechanism before processing automotive parts. The adjusting rod then pushes the clamping plate to rotate, and the clamping plate quickly clamps and locks the PCB tool. This is simple and efficient, and also ensures that the PCB tool is evenly stressed around its perimeter, improving stability and thus increasing processing accuracy. Furthermore, the tapered structure of the adjusting rod allows the clamping plate to rotate within a certain range, enabling the machine tool to clamp tools of different sizes and expanding its applicability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 4 As shown, a PCB tool clamping fixture for automotive parts processing includes a fixed cylinder 1, a docking ring 2, a clamping mechanism 3 and a limiting mechanism 4. The fixed cylinder 1 is fixed on the machine tool, and the docking ring 2 is fixed at one end of the fixed cylinder 1.

[0023] The clamping mechanism 3 for clamping and locking PCB cutting tools is connected inside the fixed cylinder 1. The clamping mechanism 3 includes a clamping plate 31, a rotating rod 32, a limiting ring 33, a linkage rod 34, and an adjusting rod 35. The rotating rod 32 is fixed to one end of the clamping plate 31 and is rotatably connected to the inner side of the docking ring 2. The limiting ring 33 is coaxially fixed inside the fixed cylinder 1. The linkage rod 34 is slidably connected inside the limiting ring 33. The tapered adjusting rod 35 is coaxially fixed to one end of the linkage rod 34 near the clamping plate 31, and one end of the clamping plate 31 slides against the outer wall of the adjusting rod 35.

[0024] The limiting mechanism 4 is located on the fixed cylinder 1 at the end away from the clamping plate 31;

[0025] The clamping mechanism 3 also includes an abutment plate 36, a support base 37, a transmission rod 38, and a throttle 39. The abutment plate 36 is coaxially fixed on the linkage rod 34 at the end away from the adjusting rod 35. The support base 37 is fixed on the fixed cylinder 1 on the side close to the abutment plate 36. The transmission rod 38 is rotatably connected to the support base 37. One end of the throttle 39 is fixed to the transmission rod 38, and the abutment plate 36 slides against one side of the throttle 39. The limiting mechanism 4 is set on the support base 37.

[0026] The limiting mechanism 4 includes a ratchet 41, a pawl 42, and a second return spring 43. The ratchet 41 is coaxially fixed on the transmission rod 38. One end of the pawl 42 is rotatably connected to the side wall of the support base 37, and the other end slides against the edge of the pawl 42. One end of the second return spring 43 is connected to the pawl 42, and the other end is connected to the support base 37.

[0027] In this utility model, by setting up a clamping mechanism 3, the PCB tool can move the adjusting rod 35 by sliding the linkage rod 34 in the clamping mechanism 3 before processing the automotive parts. Then, the adjusting rod 35 pushes the clamping plate 31 to rotate, and the clamping plate 31 quickly clamps and locks the PCB tool. This is simple and efficient, and also ensures that the PCB tool is evenly stressed around its perimeter, improving stability and thus improving processing accuracy. At the same time, the design of the tapered adjusting rod 35 allows the clamping plate 31 to rotate within a certain range, so that the machine tool can clamp tools of different sizes, thus improving its applicability. Example 2

[0028] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0029] A roller 310 is rotatably connected to one side of the throttle 39. The roller 310 abuts against the abutment plate 36. The rotation of the roller 310 reduces the wear between the abutment plate 36 and the throttle 39.

[0030] A first reset spring 311 is sleeved on the linkage rod 34. One end of the first reset spring 311 abuts against the limiting ring 33, and the other end abuts against the fixed cylinder 1. The elastic force of the first reset spring 311 enables the linkage rod 34 to quickly reset, thereby separating the adjusting rod 35 from the clamping plate 31 and enabling the clamping plate 31 to be quickly unlocked.

[0031] The fixed cylinder 1 is provided with an air guide pipe connection hole 5, and the air guide pipe connection hole 5 is connected to the internal cavity of the fixed cylinder 1. The air guide pipe connection hole 5 is connected to an external air guide pipe, thereby filling the inside of the fixed cylinder 1 with air and allowing the gas to overflow, thus preventing waste chips from entering the fixed cylinder 1 and clogging it during processing.

[0032] Working principle: When using this tool clamping fixture, first assemble the PCB tool in the fixed cylinder 1, then rotate the handle 39. The handle 39 pushes the abutment plate 36 and the linkage rod 34 to move as a whole, which in turn drives the adjusting rod 35 to move. The adjusting rod 35 then pushes the clamping plate 31 to rotate and clamp the PCB tool. At the same time as the handle 39 rotates, the ratchet 41 rotates synchronously. At this time, the pawl 42 slides at the edge of the ratchet 41 and limits and locks the ratchet 41, thereby locking the handle 39.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
