Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drilling tools, in particular to a hand electric drill fixture. Background Art
[0002] During the processing of shell parts, in order to increase the heat dissipation performance of the shell, inclined holes will be opened on the shell according to actual needs.
[0003] At present, in the process of opening an inclined hole in a shell, the shell is often fixed on a five-axis turntable by clamping furniture, and then the five-axis turntable is installed on a vertical machining center. Through the rotation of the five-axis turntable, the position where the inclined hole needs to be processed on the shell is located under the drill bit of the vertical machining center, and then a drill sleeve is installed at the position where the inclined hole is opened on the shell, and the drill bit of the vertical machining center is controlled to open the inclined hole in the shell. Although this method can complete the opening of the inclined hole on the shell, after opening an inclined hole on the shell, the method needs to rotate the A axis and C axis of the five-axis turntable, adjust the position of the shell, so that the position where the inclined hole needs to be opened on the shell is located under the drill bit of the vertical machining center, and then perform another inclined hole processing. It takes at least 25 minutes to complete the process operation of all the inclined holes on a shell part, and then this method is time-consuming and labor-intensive to process the inclined hole on the shell, and the processing efficiency is low; at the same time, during the adjustment process of the five-axis turntable, if the A axis and the C axis are not adjusted in place, it is easy for the vertical machining center to have a large error when processing the inclined hole on the shell, which makes the shell parts scrapped and reduces the production efficiency of the shell.
[0004] At the same time, in order to facilitate the opening of the inclined hole on the shell, a hand drill is also used to directly open the inclined hole on the shell. In the process of opening the inclined hole, there is no corresponding clamp to position and guide the drill bit of the hand drill. When the hole opening starts, the drill bit of the hand drill is likely to slip at the position where the inclined hole is opened on the shell, causing damage to the shell and affecting the efficiency of the shell opening.

[0019] Preferably, the connecting member is a mounting screw.
[0020] Compared with the prior art, the utility model has the following beneficial technical effects:
[0021] The utility model discloses a hand-held electric drill clamp, in which the device is fixed on a shell body through a connecting part, and then a drill sleeve is installed in a guide part, and the drill bit of the hand-held electric drill is positioned and guided through the cooperation of the guide part and the drill sleeve, and a hole is drilled at a position where an inclined hole is required to be opened on the shell body, and after a worker uses the hand-held electric drill to open an inclined hole, he only needs to move the position of the hand-held electric drill to open another inclined hole on the shell body, and the efficiency of opening holes on the shell body is high, and in the process of opening the inclined holes, the drill bit of the hand-held electric drill will not slide, and thus will not cause damage to the shell body, thereby improving the efficiency of opening the inclined holes on the shell body; at the same time, the clamp can be used in conjunction with the hand-held electric drill to complete the process of opening an inclined hole on the shell body in 15 minutes, thereby greatly reducing the time for opening holes on the shell body and improving the efficiency of opening holes.
[0022] Furthermore, the guide part of the device includes a positioning pin, a positioning hole is provided on the positioning pin, and a drill sleeve is installed in the positioning hole. The positioning pin can fix the position of the drill sleeve, so that the drill sleeve has better stability during the installation process. The cooperation between the positioning pin and the positioning hole not only limits the movement range of the drill sleeve, but also provides a solid support for it, so that the drill sleeve is not easy to deviate or shake during the working process, which helps to ensure the accuracy and consistency of the drilling operation and improve the work efficiency and product quality.
[0023] Furthermore, the positioning hole and the drill sleeve in the device are interference fit, so that the positioning hole and the drill sleeve are tightly combined, eliminating the gap, thereby significantly improving the matching accuracy. This high-precision fit helps to ensure the stable position of the drill sleeve in the positioning hole, reduce errors caused by looseness or vibration, affecting the accuracy of the inclined hole, and improve the working accuracy and reliability of the entire device.
[0024] Furthermore, the positioning part of the device includes a connecting piece, which is installed in the connecting hole set on the positioning pin and the mounting hole set on the drilling template. The connecting piece is a mounting screw. The mounting screw cooperates with the internal thread of the mounting hole, so that the positional relationship between the positioning pin and the drilling template is accurately controlled, which helps to reduce assembly errors, improve positioning accuracy, and ensure that the device can maintain an accurate relative position during operation. At the same time, the firm connection of the mounting screw also enhances the reliability of positioning and prevents relative movement or misalignment between components.
[0025] Furthermore, in the device, a positioning groove is also provided on the drilling template, and the top of the positioning pin is installed in the positioning groove. The positioning groove accurately positions the top of the positioning pin, so that the relative position between the drilling template and the positioning pin can be ensured to be accurate, which effectively reduces the assembly error and improves the positioning accuracy of the entire device, thereby ensuring the accuracy of the processing or assembly operation. At the same time, the close combination of the positioning groove and the top of the positioning pin also enhances the stability of the structure, so that a stable connection is formed between the drilling template and the positioning pin, which prevents loosening or deviation that may occur during the working process and ensures the stable operation of the device.
