Description

Technical Field

[0001] This utility model relates to a drilling fixture for a protective copper sheet on a capsule demolding clamp, belonging to the technical field of capsule production auxiliary equipment. Background Technology

[0002] In the capsule manufacturing industry, there is usually a process of removing semi-finished capsules from capsule molds. Currently, demolding clamps are used to hold the semi-finished capsules and scrape them off the molds. However, since both the molds and demolding clamps are made of iron, long-term use and scraping can damage the molds and affect normal capsule production.

[0003] To address this, Chinese patent document CN207388133U discloses a demolding clamp, comprising a first clamping bar, a second clamping bar, a spring, and a protective copper sheet. The first clamping bar has a hinge plate in its middle, and the second clamping bar has a hinge hole in its middle. The first and second clamping bars are hinged together by the hinge plate and the hinge hole. The spring is positioned between the first and second clamping bars. Each of the first and second clamping bars has a clamping portion at one end. The protective copper sheet is welded to the upper and lower sides of the clamping portion. By welding a protective copper sheet to the clamping portion of the demolding clamp, and ensuring that the hole diameter of the copper sheet is smaller than the clamping hole diameter, the copper sheet rubs against the mold during daily use. Because the copper sheet is relatively soft, this significantly reduces mold wear and extends the mold's lifespan. Furthermore, the protective copper sheet on the demolding clamp wears down after use.

[0004] When manufacturing the protective copper sheet for the demolding clamp, the process typically involves first installing and fixing the protective copper sheet onto the clamp, then drilling through holes in the protective copper sheet using a drilling machine, and finally dividing the protective copper sheet into two parts using wire cutting or other processing methods. The accuracy of the position of the through holes drilled on the protective copper sheet directly affects the effectiveness of the demolding clamp, such as whether it can successfully demold the capsule.

[0005] Therefore, how to position and clamp the release clamp onto the drilling machine before drilling through holes to ensure the accuracy of the position of the through holes drilled on the copper sheet is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a drilling fixture for the protective copper sheet on the capsule demolding clamp.

[0007] This utility model is achieved through the following technical solution:

[0008] A protective copper sheet drilling fixture for capsule demolding includes a base and a center hole positioning component, a clamping component, a pressing component and a drill bit guide component disposed on the base. The center hole positioning component and the pressing component are both located between the clamping component and the drill bit guide component.

[0009] The base is mounted on a bottom plate, and slots are provided at both ends of the bottom plate.

[0010] The central hole positioning component is a central shaft, one end of which is connected to the base, and the central axis of the central shaft is perpendicular to the base.

[0011] The clamping assembly includes a vertical plate and a top rod. The vertical plate is located at one end of the base and has a threaded hole. The top rod is threadedly connected to the threaded hole on the vertical plate.

[0012] The top rod is T-shaped and includes a handle and a screw. One end of the screw is connected to the middle of the handle, and the central axis of the screw is perpendicular to the central axis of the handle.

[0013] The screw is threaded into the threaded hole on the vertical plate.

[0014] The base has limit blocks on both sides of the top rod.

[0015] The base has a positioning groove at a position corresponding to the limiting block.

[0016] The clamping assembly is a vertical quick clamp.

[0017] The drill bit guide assembly includes a support block and a drill sleeve. The support block has a through hole A in a direction perpendicular to the base. The drill sleeve is disposed on the support block and is slidably connected to the through hole A.

[0018] The base has a blind hole for avoidance at a position coaxial with the through hole A.

Detailed Implementation

[0029] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0030] like Figures 1 to 8 As shown, the protective copper sheet drilling fixture for capsule demolding according to this utility model includes a base 2 and a center hole positioning component 3, a clamping component 4, a pressing component 5, and a drill bit guide component 6 disposed on the base 2. The center hole positioning component 3 and the pressing component 5 are both located between the clamping component 4 and the drill bit guide component 6. Figure 6 and Figure 7 As shown, during use, the protective copper sheet 8 is first installed and fixed onto the demolding clamp 7 using screws. Then, the clamp is installed and fixed onto the worktable of the drilling machine, and the position of the clamp is adjusted so that the guide hole on the drill bit guide assembly 6 is coaxially arranged with the drill bit on the drilling machine. Then, the center hole 70 on the demolding clamp 7 is positioned by the center hole positioning assembly 3. The part of the demolding clamp 7 away from the protective copper sheet 8 is pressed by the clamping assembly 4, so that the demolding clamp 7 is fixedly installed on the base 2. At this time, the position on the protective copper sheet 8 that needs to be drilled is aligned with the guide hole and the drill bit. Next, the demolding clamp 7 is pressed by the clamping assembly 5 to further improve the installation stability and reliability of the demolding clamp 7 on the base 2. Finally, the drilling machine is started, and the drill bit passes through the guide hole to accurately drill the through hole B80 on the protective copper sheet 8.

[0031] It can be seen that the mold release clamp 7, on which the protective copper sheet 8 is installed, can be positioned and fixed on the worktable of the drilling machine by the fixture, ensuring the positional accuracy of the through hole B80 drilled on the protective copper sheet 8.

[0032] The base 2 is mounted on the base plate 1, and slots 100 are provided at both ends of the base plate 1. This facilitates the installation and fixing of the base 2 onto the worktable of the drilling machine via the base plate 1.

[0033] The center hole positioning assembly 3 is a center shaft, one end of which is connected to the base 2, and the central axis of the center shaft is perpendicular to the base 2. In use, the center shaft is clearance-fitted with the center hole 70 on the demolding clamp 7.

[0034] The clamping assembly 4 includes a vertical plate 40 and a push rod 41. The vertical plate 40 is located at one end of the base 2 and has a threaded hole. The push rod 41 is threadedly connected to the threaded hole on the vertical plate 40.

[0035] The top rod 41 is T-shaped and includes a handle 411 and a screw 410. One end of the screw 410 is connected to the middle of the handle 411, and the central axis of the screw 410 is perpendicular to the central axis of the handle 411.

[0036] The screw 410 is threadedly connected to the threaded hole on the upright plate 40. In use, the screw 410 is parallel to the base 2. After positioning the center hole 70 on the demolding clamp 7 by the central shaft, rotate the screw 410 to push it between the two clamping arms of the demolding clamp 7 until it tightens and fixes the demolding clamp 7.

[0037] The base 2 has limiting blocks 42 on both sides of the top rod 41. The limiting blocks 42 limit the part of the demolding clamp 7 away from the protective copper sheet 8, so as to prevent the demolding clamp 7 from rotating around the central axis during the drilling of the through hole B80.

[0038] The base 2 has a positioning groove 21 at a position corresponding to the limiting block 42. The positioning groove 21 is used to position the limiting block 42 to improve the accuracy of the installation position of the limiting block 42 on the base 2.

[0039] The clamping component 5 is a vertical quick clamp. In use, the vertical quick clamp is model 102B, which can be directly purchased and is existing technology; therefore, it will not be described further here.

[0040] The drill bit guide assembly 6 includes a support block 60 and a drill sleeve 61. The support block 60 has a through hole A600 along a direction perpendicular to the base 2. The drill sleeve 61 is mounted on the support block 60 and slidably connected to the through hole A600. In use, the drill sleeve 61 is clearance-fitted with the through hole A600, and the inner hole of the drill sleeve 61 serves as the guide hole, guiding the drill bit through the inner hole of the drill sleeve 61.

[0041] The base 2 has a blind hole 20 at a position coaxial with the through hole A600.
