Description

Technical Field

[0001] This utility model belongs to the field of aluminum die casting processing technology, and specifically relates to a fixture for drilling holes in aluminum die castings. Background Technology

[0002] In the process of machining aluminum die castings, drilling is required. To ensure the effectiveness of drilling, a fixture is needed to hold and fix the parts. While existing fixtures for drilling aluminum die castings can meet the basic requirement of holding and fixing the parts, they typically can only hold one part at a time. After drilling one part, the drilling process needs to be paused for a considerable period until the drilled part is unloaded and the next part is loaded and clamped. In other words, when drilling multiple die castings, a significant amount of time is spent on loading and unloading, which affects the overall efficiency of drilling multiple die castings and fails to fully meet processing needs. Utility Model Content

[0003] In view of this, this utility model addresses the shortcomings of the prior art by providing a fixture for drilling aluminum die castings. It not only meets the basic requirement of clamping and fixing aluminum die castings to assist in drilling, but also automatically moves multiple die castings sequentially to the bottom of the drilling structure, so that the drilling structure does not need to be paused to wait for the die castings to be loaded and unloaded one by one.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a fixture for drilling holes in aluminum die-casting parts, including a processing table, a drilling structure set in the middle of the processing table, a support leg set at the bottom of the processing table, vertical plates set on both sides of the processing table, and first telescopic push rods set horizontally on the two vertical plates. Placement frames that are slidably connected to the top of the processing table are set on the output shafts of the two first telescopic push rods. Placement slots are snapped into the two placement frames. Multiple placement grooves for snapping and placing die-casting parts are opened in the placement slots. Guide insertion holes are also opened on the vertical plates. Guide rods located at the side ends of the first telescopic push rods and inserted into the guide insertion holes are also set on the placement frames.

[0005] As a further improvement of this utility model, a connecting groove is provided on the processing table along the left and right directions, and a connecting slider is provided at the bottom of the placement frame to slide in connection with the connecting groove. The vertical cross-section of both the connecting groove and the connecting slider is T-shaped. The cooperation of the connecting groove and the connecting slider enables the sliding connection between the placement frame and the processing table; because the vertical cross-section of both the connecting groove and the connecting slider is T-shaped, it can effectively prevent the placement frame from warping relative to the processing table.

[0006] As a further improvement of this utility model, a support pad is also provided at the bottom corner of the placement groove. The support pad can elevate the die-casting part placed in the placement groove, leaving space between the bottom of the die-casting part and the bottom of the placement groove, thereby effectively avoiding damage to the bottom of the placement groove during the drilling process of the die-casting part.

[0007] As a further improvement of this utility model, a handle is also provided on the placement slot. The handle allows for easy movement of the placement slot, facilitating the locking and unlocking of the placement slot and the placement frame.

[0008] As a further improvement of this utility model, the processing table is also provided with a discharge hole that communicates with the connecting slide. Through the discharge hole, debris and other impurities that enter the connecting slide can be easily discharged.

[0009] As a further improvement of this utility model, a second telescopic push rod is vertically arranged on the front side of the middle part of the processing table, a pressing frame is arranged on the output shaft of the second telescopic push rod, a connecting tube is arranged on the rear side of the top of the processing table, and a connecting rod that is inserted and connected to the connecting tube is arranged on the pressing frame.

[0010] As a further improvement of this utility model, a reinforcing plate is also provided between the vertical plate and the processing table. The reinforcing plate enhances the connection between the vertical plate and the processing table.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Firstly, workers can use the first telescopic push rod to move multiple die-cast parts sequentially to the bottom of the drilling structure, thereby performing drilling processing on multiple die-cast parts; and after completing the pressing processing of a die-cast part in one placement slot, a die-cast part in another placement slot can be drilled. During this interval, the previous placement slots and die-cast parts can be loaded and unloaded in batches, so that the drilling structure can continuously perform drilling processing without having to pause and wait for the die-cast parts to be loaded and unloaded one by one.

[0013] Secondly, through the cooperation of the second telescopic push rod, the pressing frame, the connecting sleeve and the connecting rod, the top of the die-casting part that has moved below the drilling structure can be pressed down and fixed, preventing the die-casting part from being easily pulled out of the placement slot by the drilling structure during the drilling process.

Detailed Implementation

[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] like Figure 1 , 2 As shown in Figure 3, a fixture for drilling holes in aluminum die castings includes a processing table 101, a drilling structure is set in the middle of the processing table 101, a support leg 102 is set at the bottom of the processing table 101, and vertical plates 103 are respectively set on both sides of the processing table 101. A first telescopic push rod 104 is horizontally set on each of the two vertical plates 103. The fixed end of the first telescopic push rod 104 is connected to the side end of the vertical plate 103, and the output shaft of the first telescopic push rod 104 passes through the vertical plate 103.

[0023] Each of the two first telescopic push rods 104 has a placement frame 105 that is slidably connected to the top of the processing table 101. Each of the two placement frames 105 has a placement slot 106 that is snapped into it. The placement slot 106 has multiple placement grooves 107 for snapping into and placing the die-cast parts. The vertical plate 103 also has a guide hole 108. The placement frame 105 also has a guide rod 109 located on the side of the first telescopic push rod 104 and inserted into the guide hole 108. By connecting the guide rod 109 to the guide hole 108, the movement of the placement frame 105 can be guided, and the telescopic push rod can be prevented from being easily damaged by non-lateral forces.

[0024] The placement frame 105 is provided with a first fixing cylinder 301 that is snapped and fixed to the output shaft of the first telescopic push rod 104. The first fixing cylinder 301 is provided with a first fixing bolt 302 for screwing and fixing the output shaft of the first telescopic push rod 104. The output shaft of the first telescopic push rod 104 is provided with a first threaded fixing hole for screwing and connecting with the first fixing bolt 302.

[0025] like Figure 1 , 4 As shown, a connecting groove 110 is provided on the processing table 101 along the left and right directions. A connecting slider 111 is provided at the bottom of the placement frame 105, which is slidably connected to the connecting groove 110. The vertical cross-section of both the connecting groove 110 and the connecting slider 111 is T-shaped. The cooperation between the connecting groove 110 and the connecting slider 111 enables the sliding connection between the placement frame 105 and the processing table 101. Because the vertical cross-section of both the connecting groove 110 and the connecting slider 111 is T-shaped, it can effectively prevent the placement frame 105 from warping relative to the processing table 101.

[0026] Workers can first attach and fix multiple die-cast parts to be drilled to multiple placement grooves 107, thereby placing multiple die-cast parts to be drilled into the placement grooves. Then, the die-cast parts containing the parts to be drilled are attached and placed into the placement frame 105. After that, the output shaft of the first telescopic push rod 104 on the left can be driven to extend a certain length, moving multiple die-cast parts to the bottom of the drilling structure in sequence, and the drilling structure will drill holes in the multiple die-cast parts in sequence.

[0027] After the pressing of multiple die-cast parts in the left placement slot 106 is completed, the output shaft of the first telescopic push rod 104 on the left is driven to shorten its movement length, causing the left placement frame 105 and multiple punched die-cast parts to reset to the left. Then, the output shaft of the first telescopic push rod 104 on the right is driven to a certain length, so that the multiple die-cast parts in the right placement slot 106 are moved sequentially to the bottom of the punching structure for punching. While punching the die-cast parts on the right, the placement slot 106 and the die-cast parts on the left can be batch unloaded and loaded together. This allows the punching structure to continuously punch multiple die-cast parts without having to pause and wait for the die-cast parts to be loaded and unloaded one by one, thereby improving the efficiency of punching multiple die-cast parts.

[0028] According to another embodiment of the present invention, such as Figure 4 As shown, a support block 115 is also provided at the bottom corner of the placement groove 107. When the die casting is placed into the placement groove 107, the support block 115 can lift and support the die casting, leaving space between the bottom of the die casting and the bottom of the placement groove 107, thereby effectively avoiding damage to the bottom of the placement groove 107 during the drilling process of the die casting.

[0029] According to another embodiment of the present invention, such as Figure 2 As shown, a handle 112 is also provided on the placement slot 106. With the help of the handle 112, the worker can easily move the placement slot 106 to easily put or take out the placement frame 105.

[0030] According to another embodiment of the present invention, such as Figure 4 As shown, the processing table 101 is also provided with a discharge hole 113 that communicates with the connecting slide 110. When debris or other impurities enter the connecting slide 110, they can be quickly discharged through the discharge hole without the need for tools such as a vacuum cleaner.

[0031] According to another embodiment of the present invention, such as Figure 1 , 5As shown, a second telescopic push rod 201 is vertically arranged on the front side of the middle part of the processing table 101. A pressing frame 202 is arranged on the output shaft of the second telescopic push rod 201. A connecting sleeve 203 is arranged on the rear side of the top of the processing table 101. A connecting rod 204 that is inserted and connected to the connecting sleeve 203 is also arranged on the pressing frame 202. A second fixing sleeve 303 is arranged on the pressing frame 202 and is snapped and fixed to the output shaft of the second telescopic push rod 201. A second fixing bolt 304 for screwing and fixing the output shaft of the second telescopic push rod 201 is arranged on the output shaft of the second telescopic push rod 201. A second threaded fixing hole for screwing and connecting to the second fixing bolt 304 is opened on the output shaft of the second telescopic push rod 201.

[0032] Once a die-cast part to be drilled is moved below the drilling structure, the output axis of the second telescopic push rod 201 can be driven to shorten by a certain length. Under the guidance of the insertion of the connecting sleeve 203 and the connecting rod 204, the pressing frame 202 is driven to move downward until it presses against the die-cast part. This prevents the die-cast part from being moved or falling out of the placement groove 107 and placement slot 106 by the drilling structure during the subsequent drilling process.

[0033] After the die-casting part is drilled, the output axis of the second telescopic push rod 201 is extended upward by a certain length, which drives the pressing frame 202 to reset upward.

[0034] According to another embodiment of the present invention, such as Figure 2 As shown, a reinforcing plate 114 is also provided between the vertical plate 103 and the processing table 101. The two ends of the reinforcing plate 114 are welded and fixed to the vertical plate 103 and the processing table 101, respectively. The reinforcing plate 114 can enhance the connection between the vertical plate 103 and the processing table 101.

[0035] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
