Description

Technical Field

[0001] This utility model relates to the field of drilling positioning technology, and in particular to a drilling guide positioning device for mechanical parts. Background Technology

[0002] In the process of drilling mechanical parts, a center punch is used to punch a recess on the surface of the workpiece in order to guide and position the subsequent drilling work. This recess can clearly mark the center position of the hole and provide a precise initial reference point for subsequent drilling operations.

[0003] When using a center punch, it is usually necessary to strike the strike cap of the center punch with a hammer. Since the hand-held part is very close to the striking part, if the hammer head swings off course, slips, or the operator is fatigued or distracted during the striking process, it is very easy to directly strike the fingers holding the center punch, causing serious crushing injuries, bruising, or even fractures, which poses a significant safety hazard. It not only causes physical harm to the workers but also affects work efficiency. To address this issue, we propose a drilling guide and positioning device for mechanical parts. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drilling guide and positioning device for mechanical parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A drilling guide and positioning device for mechanical parts includes a punch rod, a strike cap fixedly connected to the top end of the punch rod, a punch head fixedly connected to the bottom end of the punch rod, a connecting sleeve sleeved on the outer side of the punch rod, and a protective baffle plate provided at the bottom of the connecting sleeve. A through groove is provided at the center of the protective baffle plate, and anti-slip texture is provided on the outer wall of the punch rod.

[0006] Preferably, the top of the protective baffle is symmetrically connected with connecting rods, and the inside of the connecting sleeve is provided with a connecting groove that matches the connecting rod, and the inner wall of the connecting groove is connected to the connecting rod by a connecting spring.

[0007] Preferably, a crossbar is inserted into the top of the connecting sleeve, and a connecting plate is fixedly connected to the end of the crossbar. A mating groove adapted to the crossbar is opened on the top of the punch, and a slot is opened at the position corresponding to the connecting plate on the top of the punch.

[0008] Preferably, a protective pad is glued to the outside of the protective baffle, and the cross-section of the protective pad is set as a U-shaped structure.

[0009] Preferably, the cross-section of the connecting rod and the connecting groove is rectangular, and the outer wall of the connecting rod and the inner wall of the connecting groove are tightly fitted together.

[0010] Preferably, the outer surface of the crossbar is provided with external threads, and the inner wall of the mating groove is provided with internal threads.

[0011] Preferably, the outer wall of the punch is connected to a limiting plate, and the limiting plate is symmetrically distributed at the left and right ends of the punch.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device is equipped with a connecting sleeve and a protective baffle. During use, the protective baffle separates the gripping part from the impact cap in space, ensuring that the operator's hand is always in a safe gripping area. This eliminates the possibility of the hammer hitting and injuring the fingers, thus effectively improving the safety of the device during use.

[0013] 2. This device is equipped with a connecting groove and a connecting spring. During use, the connecting groove and the connecting spring work together to push the connecting rod and the connecting groove to move under force when the hammer head slips and collides with the protective baffle. With the connection of the connecting spring, the collision force can be buffered, thus effectively ensuring the service life of the protective baffle. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4A drilling guide and positioning device for mechanical parts includes a punch rod 1, a strike cap 2 fixedly connected to the top end of the punch rod 1, a punch head 12 fixedly connected to the bottom end of the punch rod 1, a connecting sleeve 3 sleeved on the outer side of the punch rod 1, and a protective baffle 4 provided at the bottom of the connecting sleeve 3. A through groove is provided at the center of the protective baffle 4, which allows the protective baffle 4 to slide up and down. Anti-slip texture 13 is provided on the outer wall of the punch rod 1, which can effectively improve the stability of the user when holding the punch rod 1.

[0018] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the top of the protective baffle 4 is symmetrically connected with connecting rods 5, and the inside of the connecting sleeve 3 is provided with a connecting groove 6 that is compatible with the connecting rod 5. The inner wall of the connecting groove 6 is connected to the connecting rod 5 through a connecting spring 7. When the hammer collides with the protective baffle 4, the protective baffle 4 can be moved downward by the cooperation of the connecting rod 5, the connecting groove 6 and the connecting spring 7, so as to buffer and weaken the collision force.

[0019] Furthermore, refer to Figure 2 and Figure 3 It can be seen that a crossbar 9 is inserted into the top of the connecting sleeve 3, and a connecting plate 10 is fixedly connected to the end of the crossbar 9. A mating groove adapted to the crossbar 9 is opened on the top of the punch rod 1. A slot 11 is opened at the position corresponding to the connecting plate 10 on the top of the punch rod 1. The connecting plate 10 can be accommodated by opening the slot 11. When the protective baffle 4 is damaged, the staff can pull the crossbar 9 out of the mating groove opened on the top of the punch rod 1 to pull out the connecting sleeve 3 and the protective baffle 4 from the top of the punch rod 1 for replacement.

[0020] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the protective baffle 4 is bonded with a protective pad 8 on the outside, and the cross section of the protective pad 8 is set as a U-shaped structure. The protective pad 8 set by the U-shaped structure can cover and protect the upper and lower sides of the protective baffle 4, thereby further ensuring the service life of the protective baffle 4.

[0021] Furthermore, refer to Figure 4 It can be seen that the cross-sections of the connecting rod 5 and the connecting groove 6 are set as rectangles, and the outer wall of the connecting rod 5 and the inner wall of the connecting groove 6 are tightly fitted. The connecting rod 5 and the connecting groove 6, which are set with a rectangular structure, can effectively ensure the stability of the protective baffle 4 when it slides up and down.

[0022] Furthermore, refer to Figure 2 and Figure 3It can be seen that the outer surface of the crossbar 9 is provided with external threads, and the inner wall of the mating groove is provided with internal threads. The internal and external threads are not shown in the figure. Through the threaded engagement of the crossbar 9 and the mating groove, the tightness of the connection between the connecting sleeve 3 and the punch 1 can be effectively guaranteed.

[0023] Furthermore, refer to Figure 2 It can be seen that the outer wall of the punch rod 1 is connected to the limiting plate 14, and the limiting plate 14 is symmetrically distributed on the left and right ends of the punch rod 1. When in use, the operator can hold the outer wall of the punch rod 1 located below the limiting plate 14. By setting the limiting plate 14, the protective baffle 4 can be limited and blocked, so as to effectively prevent the protective baffle 4 from colliding with the operator's hand, thereby improving the safety of the device during use.

[0024] Working Principle: When using this utility model, the operator can first hold the anti-slip texture 13 and align the punch 12 with the position to be drilled. Then, the hammer can be used to strike the impact cap 2 to punch a pit on the surface of the workpiece, thereby guiding and positioning the drilling point. When the impact cap 2 is struck, the protective baffle 4 with a large cross-sectional area can separate the holding part from the impact cap 2 in space, so that the operator's hand is always in the safe holding area, eliminating the possibility of hammering and injuring the fingers. Even if the hammer slips and collides with the protective baffle 4, it will first collide with the protective pad 8 glued to the outside of the protective baffle 4 to achieve initial buffering of the impact force. In addition, the connecting rod 5 connected to the top of the protective baffle 4 will also slide along the inner wall of the connecting groove 6 under force, and will squeeze the connecting spring 7 connected to the top of the connecting rod 5 to deform under force, thereby achieving further buffering of the impact force and thus protecting the protective baffle 4. The above is the complete working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
