Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically a sidewall drilling clamp for automotive parts. Background Technology

[0002] When drilling the sidewalls of cylindrical automotive parts, different methods can be flexibly selected according to different needs. If the goal is to be economical and practical, suitable for small batches and where high precision is not required, a special fixture can be used in conjunction with a regular drilling machine. For example, a fixture with a receiving hole, a clearance through hole, and a limiting plate can be designed. The clearance through hole is aligned with the drill bit of the drilling machine and fixed. The cylindrical part is inserted into the receiving hole, and with the help of the limiting plate and manual clamping, a regular radial drilling machine is used to allow the drill bit to press down through the clearance through hole to complete the drilling. This method is commonly used for machining cylindrical parts such as automotive fuel plunger pumps.

[0003] In the prior art, a drilling jig for processing automotive parts, disclosed in publication number "CN216781059U", includes a base. Fixed frames are fixedly connected to both sides of the upper surface of the base. A strip-shaped groove is formed on one opposite side of each of the two fixed frames. Threaded rods are vertically arranged inside each of the two fixed frames. The bottom end of the threaded rod is rotatably connected to the bottom wall of the fixed frame. The top end of the threaded rod passes through the top wall of the fixed frame and is connected to a drive motor. A threaded sleeve is threadedly connected to the outside of the threaded rod. A sliding rod passes vertically through the threaded sleeve. A connecting rod is fixedly connected to the side wall of the threaded sleeve. The end of the connecting rod away from the threaded sleeve passes through the strip-shaped groove, and a clamping plate is fixedly installed at its end. In this invention, when in use, the automotive parts to be processed are placed on the protrusion. Then, the drive motor moves the clamping plate up and down by operating in different directions, thus securely fixing the parts between the clamping plate and the protrusion. This jig is easy to adjust and has high working efficiency.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] Existing fixtures for positioning angle components mostly use an indexing instrument for angle adjustment. However, the positions of the positioning holes on the indexing instrument are often fixed, making it difficult to achieve infinite and flexible position adjustment. This makes it impossible to accurately distribute the positioning components at any angle, making it difficult to adapt to diverse needs when machining holes of different angles, thus limiting the ability to machine complex angle holes.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Please see Figure 1-5 This utility model provides a technical solution:

[0030] This automotive parts sidewall drilling fixture is used for precise drilling of the sidewalls of cylindrical automotive parts from multiple angles.

[0031] The base 1 serves as the basic load-bearing component of the entire fixture. The vertical support plate 2 is vertically fixed to the base 1, and the vertical angle between the two is positioned by the positioning block 15 on the base 1 to ensure the accurate positioning of the vertical support plate 2 after installation. The horizontal support plate 3 is fixed to the vertical support plate 2, and together with the vertical support plate 2, they form the frame support structure of the fixture.

[0032] The base 1 is provided with several connecting grooves 17 for fixing the device to the drilling equipment.

[0033] The support shaft 4 is used to support the cylindrical workpiece. It passes through the vertical support plate 2 and is rotatably connected to the vertical support plate 2 through the bearing 16, so that the support shaft 4 can rotate smoothly relative to the vertical support plate 2. The support shaft 4 is provided with several chip-collecting grooves 401 to collect the chips generated during drilling and to make way for the drill bit. One end of the support shaft 4 is fitted with a clamping block 13 through a threaded connection to axially clamp the workpiece sleeved on the support shaft 4; the other end is fixedly connected to the adjusting plate 5, which drives the adjusting plate 5 to rotate synchronously.

[0034] Adjustment disc 5 is a key component for achieving multi-angle positioning of the workpiece.

[0035] The side wall of the adjusting disc 5 has an annular T-shaped groove 501. Multiple adjusting blocks 6 are slidably fitted into the T-shaped groove 501 and can slide flexibly along the groove. That is, the adjusting blocks 6 can stop at any angle position in the groove, but will not rotate within the T-shaped groove 501. Each adjusting block 6 is fixed with a bolt 7, which passes through the adjusting block 6 and extends outward. A nut 8 is fitted onto the bolt 7, and the nut 8 is threaded into the bolt 7. When the nut 8 is tightened, the friction is increased by using an anti-slip pad (fitted on the bolt 7 and located between the nut 8 and the contact surface of the adjusting disc 5), pressing the adjusting block 6 onto the adjusting disc 5 and fixing its position. The other end of the bolt 7 is fixed with a positioning recess 9, which is used to cooperate with the positioning pin 11.

[0036] The adjusting disc 5 has several indexing grooves 505 to help determine the rotation angle of the adjusting disc 5 and achieve precise indexing positioning. The adjusting disc 5 also has weight-reducing holes 502 to reduce its own weight; a handle 503 is fixedly attached, and a handle sleeve 50301 is rotatably fitted on the handle 503 to facilitate the operator to rotate the adjusting disc 5; anti-slip grooves 504 are provided on the side wall to enhance the anti-slip effect when tightening the nut 8.

[0037] A connecting plate 10 is fixed on the horizontal support plate 3, and a positioning pin 11 slides through the connecting plate 10. One end of the positioning pin 11 is provided with a positioning protrusion 12 that matches the positioning recess 9. A spring 1101 is sleeved on the positioning pin 11, and the spring 1101 is located between the positioning protrusion 12 and the connecting plate 10. When it is necessary to lock the angle of the adjusting disc 5, the spring 1101 pushes the positioning protrusion 12 to engage with the positioning recess 9 to lock the angle of the adjusting disc 5. When the adjusting disc 5 is rotated, the positioning pin 11 can be manually pulled to overcome the force of the spring 1101, so that the positioning protrusion 12 and the positioning recess 9 are separated, and the lock is released.

[0038] Several machining positioning holes 14 are provided on the horizontal support plate 3 for use with external drilling equipment or auxiliary positioning parts to provide a precise positioning reference for drilling operations and ensure accurate drilling positions on the side walls of automotive parts.

[0039] Workflow

[0040] The cylindrical workpiece is placed on the support shaft 4, and the clamping block 13 is rotated to axially clamp the workpiece through the threaded engagement.

[0041] According to the angle requirements of the side wall of the cylindrical component to be machined, the positions of multiple adjusting blocks 6 in the T-shaped slide 501 are adjusted so that the positioning recesses 9 corresponding to each adjusting block 6 are distributed at the predetermined angle positions.

[0042] Tighten the nut 8 on the bolt 7 to enhance friction with the anti-slip pad, and fix the adjusting block 6 on the adjusting plate 5 to ensure the accurate position of the positioning recess 9.

[0043] Rotating the handle 503 causes the adjusting plate 5, the support shaft 4, and the workpiece to rotate, and the first target angle is determined with the help of the indexing groove 505.

[0044] Loosen the positioning pin 11, and the spring 1101 pushes the positioning protrusion 12 to lock with the corresponding positioning recess 9, thus locking the current angle.

[0045] Using the machining positioning hole 14 on the horizontal support plate 3, and in conjunction with the drilling equipment, the first hole is drilled on the side wall of the workpiece.

[0046] Angle switching and continuous processing:

[0047] When it is necessary to process the hole at the next angle, manually lift the locating pin 11 to separate the locating protrusion 12 from the locating recess 9.

[0048] Rotate the adjustment disc 5 to the position of the next positioning recess 9, which corresponds to the angle of the next hole.

[0049] Loosen the locating pin 11, and the locating protrusion 12 will engage with the locating concave block 9 again to lock the new angle and proceed with drilling the next hole.

[0050] Repeat this process until all preset angle drilling operations are completed.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
