Abstract
Description
Technical Field
[0001] This utility model relates to a clamp, specifically a drill press clamp based on a die-casting part, and belongs to the field of drill press clamp technology. Background Technology
[0002] Die-cast parts are formed through a die-casting process. They are mostly made of lightweight alloys such as aluminum alloys and zinc alloys, and are characterized by high dimensional accuracy and smooth surfaces, making them suitable for mass production. Due to assembly and connection requirements, drilling is often necessary. When drilling, care must be taken to ensure the material is easily deformed and the surface is protected. Precision and clamping methods must be carefully controlled to prevent damage.
[0003] In existing technologies, a vise is often used to clamp the die-casting part for subsequent drilling and machining operations. Before drilling, the operator needs to operate the rocker arm handle of the drilling machine to make the drill bit press against the mark on the die-casting part, which is the position to be drilled. Then, the position of the die-casting part is adjusted by tapping the vise until the hole position mark is aligned with the drill bit.
[0004] However, to improve drilling accuracy, the vise needs to be fixed. When machining a large number of die-cast parts, the vise needs to be frequently loosened, repositioned, and re-fixed, making the operation cumbersome and inefficient. Therefore, a drilling machine fixture based on die-cast parts is proposed here. Utility Model Content
[0005] This invention proposes a drilling machine fixture based on die castings, which can flexibly adjust the position of the fixture and quickly fix it.
[0006] This utility model is achieved through the following technical solution: a drilling machine fixture based on die casting, including a fixture, the fixture including a mounting plate, the mounting plate having a positioning hole, the positioning hole being provided so that the mounting plate and the worktable can be fixed together when needed, the mounting plate having a threaded rod threadedly connected to it, the end of the threaded rod away from the first clamping plate being fixed with a rotating plate, the rotating plate being provided to facilitate the rotation of the threaded rod.
[0007] A first clamping plate is rotatably connected to the threaded rod. When the threaded rod rotates, it will drive the first clamping plate to move relative to the second clamping plate on the mounting plate. The first clamping plate is slidably connected to the mounting plate, and the second clamping plate is fixed on the mounting plate. The mounting plate is fixed to the sliding rod.
[0008] It also includes a position adjustment component, which is mounted on the fixture. The position adjustment component includes a first arc plate and a second arc plate, which are deformable. The first arc plate is movably connected to the second arc plate, and the first and second arc plates are rotatably connected by a pin. When not in use, the pin is removed and the limiting screw is removed from the eccentric wheel handle. At this time, the first and second arc plates can be removed from the column. A fixing block is fixed on both the first and second arc plates, and a sliding rod is slidably connected inside the fixing block.
[0009] It also includes a locking component, which is disposed on the position adjustment component. The locking component includes a mounting hole and a mounting groove. The mounting hole is formed on the first arc-shaped plate and the second arc-shaped plate. The mounting groove is formed on the second arc-shaped plate. An eccentric wheel handle is rotatably connected in the mounting groove. A limit screw is threaded onto the eccentric wheel handle. The limit screw is disposed in the mounting hole and can move on the second arc-shaped plate. When the eccentric wheel handle rotates, it pulls the first arc-shaped plate through the limit screw, causing the first and second arc-shaped plates to deform. The locking component also includes a fastening block, which is slidably connected to a fixed block. The fastening block passes through the first and second arc-shaped plates and is slidably connected to them.
[0010] This utility model provides a drilling machine fixture based on die castings, which has the following beneficial effects:
[0011] 1. The mounting plate of this die-casting-based drilling machine fixture can slide on the fixed block via a sliding rod. When the mounting plate is rotated, it will rotate on the column via the sliding rod, the fixed block, the first arc plate, and the second arc plate, thereby allowing the mounting plate to move freely on the worktable. This facilitates the drill bit aligning with the drilling marks of the die-casting held by the first and second clamping plates. When locking is required, the eccentric wheel handle can be turned. This device can flexibly adjust the position of the mounting plate and quickly fix it. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.
[0022] Please see Figures 1-4 The present invention proposes the following implementation scheme: a drilling machine fixture based on die casting, including a fixture 1, the fixture 1 including a mounting plate 101, the mounting plate 101 having a positioning hole 106, the positioning hole 106 being provided so that the mounting plate 101 and the worktable 4 can be fixed together when needed, the mounting plate 101 having a threaded rod 102 threadedly connected to it, the end of the threaded rod 102 away from the first clamping plate 103 having a rotating plate 105 fixed thereto, the rotating plate 105 being provided to facilitate the rotation of the threaded rod 102.
[0023] Please refer to this carefully. Figure 1 and Figure 2 A first clamping plate 103 is rotatably connected to the threaded rod 102. When the threaded rod 102 rotates, it will drive the first clamping plate 103 to move relative to the second clamping plate 104 on the mounting plate 101. The first clamping plate 103 is slidably connected to the mounting plate 101. The second clamping plate 104 is fixed on the mounting plate 101. The mounting plate 101 is fixed to the slide rod 204.
[0024] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4It also includes a position adjustment component 2, which is disposed on the fixture 1. The position adjustment component 2 includes a first arc plate 201 and a second arc plate 202. The first arc plate 201 and the second arc plate 202 are capable of deformation. The first arc plate 201 is movably connected to the second arc plate 202.
[0025] Please refer to this carefully. Figure 3 and Figure 4 The first arc plate 201 and the second arc plate 202 are rotatably connected by a pin. When not in use, the pin is removed and the limiting screw 304 is removed from the eccentric wheel handle 303. At this time, the first arc plate 201 and the second arc plate 202 can be removed from the column 5. The first arc plate 201 and the second arc plate 202 are both fixed with fixing blocks 203, and the fixing blocks 203 are slidably connected with sliding rods 204.
[0026] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4 It also includes a locking component 3, which is disposed on the position adjustment component 2. The locking component 3 includes a mounting hole 301 and a mounting groove 302. The mounting hole 301 is opened on the first arc plate 201 and the second arc plate 202, and the mounting groove 302 is opened on the second arc plate 202. An eccentric wheel handle 303 is rotatably connected in the mounting groove 302.
[0027] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4 The eccentric wheel handle 303 is threadedly connected to a limit screw 304, which is located in the mounting hole 301. The limit screw 304 can move on the second arc plate 202. When the eccentric wheel handle 303 rotates...
[0028] The eccentric wheel handle 303 pulls the first arc plate 201 through the limiting screw 304, causing the first arc plate 201 and the second arc plate 202 to deform. The locking component 3 also includes a fastening block 305, which is slidably connected to the fixing block 203. The fastening block 305 passes through the first arc plate 201 and the second arc plate 202 and is slidably connected to the first arc plate 201 and the second arc plate 202.
[0029] Working principle: When drilling holes in the die casting, the die casting is first fixed. After the die casting is placed on the mounting plate 101, the threaded rod 102 is turned by rotating the plate 105. The threaded rod 102 will drive the first clamping plate 103 to move horizontally on the mounting plate 101. Then, the die casting is clamped by the cooperation of the first clamping plate 103 and the second clamping plate 104.
[0030] Next, the operator operates the rocker arm handle of the drilling machine, so that the drill bit of the drilling machine is against the mark on the die-cast part, that is, the position where a hole needs to be drilled. The mounting plate 101 can slide on the fixed block 203 through the slide rod 204, thereby adjusting the front and rear position of the mounting plate 101.
[0031] When the mounting plate 101 needs to be rotated, the mounting plate 101 will rotate on the column 5 via the slide rod 204, the fixing block 203, the first arc plate 201 and the second arc plate 202, thereby enabling the mounting plate 101 to move freely on the worktable 4, so that the drill bit can be aligned with the drilling mark of the die-casting part held by the first clamping plate 103 and the second clamping plate 104.
[0032] When locking is required, simply turn the eccentric wheel handle 303. The rotation of the eccentric wheel handle 303 will pull the first arc plate 201 and the second arc plate 202 closer together via the limit screw 304. The first arc plate 201 and the second arc plate 202 will deform and press tightly against the column 5, thus fixing the first arc plate 201 and the second arc plate 202. When the first arc plate 201 and the second arc plate 202 are close to each other, the column 5 will push the fastening block 305, which will press tightly against the slide rod 204, thereby fixing the slide rod 204. This device can flexibly adjust the position of the mounting plate 101 and quickly fix the mounting plate 101.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
