Description

Technical Field

[0001] This utility model relates to the technical field of drilling devices, specifically a drilling device for the wrench hole of a thread protector. Background Technology

[0002] The thread protector wrench hole drilling device is an automated or semi-automated device specifically designed for machining wrench holes on thread protectors. Its core function is to drill holes for wrench installation and removal, ensuring smooth subsequent disassembly and assembly operations of the thread protector.

[0003] Traditional thread protector wrench hole drilling devices require independent positioning operations for each hole. After a single hole is positioned, it is then processed. After processing one hole, it is necessary to switch to the next hole and repeat the entire positioning and processing process. There is a clear sequence between the drilling operations of each hole, and they cannot be carried out simultaneously. Processing a thread protector requires repeatedly switching holes and repeating the positioning and processing steps, which increases the complexity of the operation and the manual burden, resulting in low processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a hole-drilling device for thread protector wrenches, so as to solve the problem of low processing efficiency caused by existing devices drilling holes one by one in multiple steps.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A thread protector wrench hole drilling device includes a mounting plate and an electric feed drill. A tool frame assembly is detachably connected to the center of the front end of the mounting plate. Multiple adjusting brackets arranged in a ring array are fixedly connected to the front end surface of the mounting plate. Each adjusting bracket is connected to a sliding connecting frame assembly. Each connecting frame is fixedly connected to a fixed seat. Each fixed seat is fixedly connected to an electric feed drill. A guide hole is provided on the surface of the tool frame assembly corresponding to the output end of the electric feed drill.

[0007] Preferably, the connecting frame assembly includes a lower sliding seat and an upper sliding seat, which are fixedly connected. The upper sliding seat is slidably connected to the upper end of the adjusting bracket, and the lower sliding seat is slidably connected to the lower end of the adjusting bracket.

[0008] Preferably, the surface of the adjusting bracket is provided with a plurality of first screw holes arranged at equal intervals, and the sliding seat is provided with a first through hole that mates with the first screw holes.

[0009] Preferably, the device frame assembly includes a connecting plate and a positioning sleeve, the connecting plate and the positioning sleeve are fixedly connected, the surface of the connecting plate is provided with a second through hole, and the surface of the mounting plate is provided with a second screw hole that mates with the second through hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Multiple electric feed drills are fixed in a circular array on the connecting frame, corresponding one-to-one with the guide holes of the frame assembly. After starting, all electric drills can work synchronously, eliminating the need to drill holes one by one. This is especially suitable for thread protectors that require multiple sets of wrench holes, significantly shortening the processing time of a single product.

[0012] 2. The surface of the adjusting bracket has multiple equally spaced first screw holes. The connecting bracket assembly can slide back and forth along the adjusting bracket. After aligning different screw holes, it can be fixed by bolting. After replacing the bracket assembly, the correspondence between the output end of the electric drill and the guide hole can be adjusted simply by sliding the connecting bracket assembly and aligning the screw holes. The operation is simple. Attached Figure Description

[0018] 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.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution.

[0020] The thread protector wrench hole drilling device includes a mounting plate 1 and an electric feed drill 2. A device frame assembly is detachably connected to the center of the front end of the mounting plate 1. Multiple adjusting brackets 6 arranged in a ring array are fixedly connected to the front surface of the mounting plate 1. Each adjusting bracket 6 is connected to a sliding connecting bracket assembly. Each connecting bracket is fixedly connected to a fixing seat 10. Each fixing seat 10 is fixedly connected to the surface of the electric feed drill 2. A guide hole 5 is opened on the surface of the device frame assembly corresponding to the output end of the electric feed drill 2. The thread protector is placed on the positioning sleeve 4 of the device frame assembly. The operator presses the thread protector against the front end of the mounting plate 1 by hand for fit and positioning. By starting the electric feed drill 2, its output end passes through the surface of the thread protector and falls along the guide hole 5 of the device frame assembly. After the output end passes through the thread protector, the wrench hole drilling operation is completed.

[0021] The connecting frame assembly includes a lower sliding seat 8 and an upper sliding seat 9. The lower sliding seat 8 and the upper sliding seat 9 are fixedly connected, and the upper sliding seat 9 is slidably connected to the upper end of the adjusting bracket 6, while the lower sliding seat 8 is slidably connected to the lower end of the adjusting bracket 6, so as to achieve overall back-and-forth sliding.

[0022] The surface of the adjusting bracket 6 is provided with multiple equally spaced first screw holes 7, and the sliding seat 8 is provided with a first through hole that mates with the first screw holes 7. The sliding seat 8 and the upper sliding seat 9 are slid on the surface of the adjusting bracket 6, and then the first through hole is aligned with one of the first screw holes 7. A bolt is inserted and then threaded to lock it in place, so that the front and rear positions of the electric feed drill 2 can be adjusted to adapt to the position of the guide hole 5 on different tool frame components.

[0023] The device frame assembly includes a connecting plate 3 and a positioning sleeve 4. The connecting plate 3 and the positioning sleeve 4 are fixedly connected. The surface of the connecting plate 3 has a second through hole, and the surface of the mounting plate 1 has a second screw hole that mates with the second through hole. After aligning the second through hole with the second screw hole, a bolt is inserted and locked in place to complete the installation of the device frame assembly. The reverse operation allows for quick replacement of the device frame assembly.

[0024] The specific solution is as follows: Select a suitable frame assembly according to the specifications of the thread protector to be processed, attach the connecting plate 3 of the frame assembly to the center position of the front end of the mounting plate 1, and adjust the position of the connecting plate 3 so that the second through hole on the surface of the connecting plate 3 is aligned with the second screw hole on the surface of the mounting plate 1.

[0025] Take the matching bolts and insert them into the aligned second through hole and second screw hole. Use a tool to tighten the bolt threads to complete the detachable connection between the device frame assembly and the mounting plate 1. If the device frame assembly needs to be replaced later, simply unscrew the bolts in the opposite direction to remove the original assembly.

[0026] Observe the position of the guide hole 5 on the selected frame assembly to determine the front and back position of the electric feed drill 2 that needs to be adjusted. For the connecting frame assembly on each adjusting bracket 6, push the connecting frame assembly by hand so that the upper slide 9 slides along the upper end of the adjusting bracket 6 and the lower slide 8 slides along the lower end of the adjusting bracket 6, thereby driving the fixed base 10 and the electric feed drill 2 on the base to move back and forth until the electric feed drill 2 is aligned with the following components: the guide hole 5 at the corresponding position of the frame assembly, the first screw hole 7 on the surface of the adjusting bracket 6, and the upper and lower slides 8.

[0027] Take the matching bolts and insert them into the aligned first through hole and first screw hole 7. Use a tool to lock the bolt threads to fix the position of the connecting frame assembly, thereby completing the adjustment of the front and rear positions of the electric feed drill 2 to match the position of the guide hole 5 on the current tool frame assembly.

[0028] Align the thread protector to be processed with the positioning sleeve 4 of the frame assembly and slowly put it on the surface of the positioning sleeve 4, ensuring that the thread protector fits tightly with the positioning sleeve 4. Then, the operator presses the thread protector against the mounting plate 1 by hand, so that the end face of the thread protector fits against the front surface of the mounting plate 1, thereby positioning the thread protector and preventing displacement during the drilling process.

[0029] After the electric feed drill 2 is started, its output end will gradually move forward, pass through the surface of the thread protector, and fall down along the corresponding guide hole 5 on the tool frame assembly. At this time, the wrench hole drilling operation is completed.

[0030] The operator releases the hand that is pressing against the thread protector and removes the finished thread protector from the positioning sleeve 4.

[0031] 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.
