Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, and specifically, to a milling fixture for mining machinery manufacturing. Background Art

[0002] Mining machinery is mechanical equipment specifically used for mining, transportation, processing and other related operations in mines. These mechanical equipment are designed and manufactured to perform various tasks in underground or surface mine environments, and are directly used in operations such as mineral mining and beneficiation. It includes mining machinery and ore dressing machinery. The working principles and structures of prospecting machinery are mostly the same or similar to those of mining machinery used for mining the same type of minerals. Generally speaking, prospecting machinery also belongs to mining machinery. In addition, a large number of cranes, conveyors, ventilators and drainage machinery are also used in mine operations. Generally speaking, mining machinery is various mechanical equipment designed and manufactured to improve production efficiency, ensure safety and protect the health of workers in mine environments. The milling fixture used in mining machinery manufacturing is usually used to clamp workpieces for machining on a milling machine.

[0003] Since relatively large and heavy workpieces usually need to be machined in mining machinery manufacturing, the fixture needs to be able to firmly clamp the workpiece to ensure stability and safety during the machining process. There is a problem with existing clamping tools that they can usually only effectively clamp workpieces with standard shapes, and have poor clamping effects on workpieces with uneven surfaces or special shapes, which may lead to instability and accuracy problems during the machining process, affecting machining quality and efficiency.

[0004] Therefore, a milling fixture for mining machinery manufacturing is needed. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a milling fixture for mining machinery manufacturing.

[0006] The technical solution of the utility model is as follows: A milling fixture for mining machinery manufacturing, including a housing, two clamping plates are symmetrically arranged at the top of the housing, an adjusting component for driving the two clamping plates to synchronously displace to position the workpiece is arranged at the left end of the housing, and deformation pads are arranged on the opposite sides of the two clamping plates.

[0007] Preferably, a structure surface sticker one is fixedly connected to the side of the deformation pad close to the clamping plate, and a rough surface sticker one adhesively connected to the structure surface sticker one is fixedly connected to the side of the clamping plate close to the deformation pad.

[0008] Preferably, an anti-puncture pad is arranged on the side of the deformation pad away from the clamping plate for protecting the deformation pad.

[0009] Preferably, a second fleece-surface sticker is fixedly connected to one side of the deformable pad close to the anti-puncture pad, and a second structural sticker bonded to the second fleece-surface sticker is fixedly connected to one side of the anti-puncture pad close to the deformable pad.

[0010] Preferably, a test paper is fixedly connected to one side of the clamping plate close to the deformation pad, and the test paper is arranged around four sides of the deformation pad.

[0011] Preferably, the adjustment assembly includes a handle, and the inner wall of the handle is fixedly connected with a bidirectional threaded screw.

[0012] Preferably, the outer wall of the bidirectional threaded screw is threadedly connected to two driving blocks, and the two clamping plates are respectively fixedly connected to the tops of the two driving blocks.

[0013] The working principle and beneficial effects of the utility model are:

[0014] 1. The utility model can provide a more reliable, flexible and safe workpiece fixing solution by adjusting the components. At the same time, the deformability of the anti-puncture pad can be used to better fit the unevenness of the workpiece, and the gas pressure in the deformable pad helps to push the anti-puncture pad to fit more closely. In this way, the workpiece can be clamped more firmly, effectively preventing displacement or shaking during the processing, thereby improving the processing accuracy and efficiency;

[0015] 2. The utility model arranges test paper on the outside of the deformation pad to quickly detect whether the deformation pad is leaking. When the deformation pad leaks, the test paper will come into contact with the test paper to change color, which is used to indicate the leakage of the deformation pad. The staff can promptly discover and solve the leakage problem of the deformation pad, thereby avoiding downtime and additional costs caused during the workpiece processing. By regularly checking the color change of the test paper, the leaking deformation pad can be replaced in time, avoiding damage to the workpiece or reduction in processing quality due to leakage, thereby saving maintenance and replacement costs.

[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0023] Please refer to Figures 1 to 4 , the present utility model provides a technical solution for a milling machine fixture used in mining machinery manufacturing: a milling machine fixture for mining machinery manufacturing, including a housing 1, and two clamping plates 2 are symmetrically arranged at the top of the housing 1;

[0024] Furthermore, an adjusting assembly 3 for driving the two clamping plates 2 to synchronously displace to position the workpiece is arranged at the left end of the housing 1. The adjusting assembly 3 includes a rotating handle 31, the inner wall of the rotating handle 31 is fixedly connected with a bi-directional threaded lead screw 32, two driving displacement blocks 33 are threadedly connected to the outer wall of the bi-directional threaded lead screw 32, and the two clamping plates 2 are respectively fixedly connected to the tops of the two driving displacement blocks 33. Rotating the rotating handle 31 makes the bi-directional threaded lead screw 32 rotate, causing the two driving displacement blocks 33 to threadedly displace on the outer wall of the bi-directional threaded lead screw 32 until the two clamping plates 2 fix the workpiece. This can ensure that the workpiece remains stable during the operation, improve the machining accuracy and safety. At the same time, the clamping force can be adjusted, so as to adapt to workpieces of different sizes or shapes, improve the flexibility and efficiency of the operation, and can provide a more uniform clamping force, and reduce the possibility of workpiece damage or machining quality problems caused by loosening or uneven clamping. Moreover, it has self-locking property. Even after stopping rotating the rotating handle 31, the clamping force will be maintained, thus increasing the safety and convenience of the operation;

[0025] Deformation pads 4 are provided on the opposite sides of the two clamping plates 2. On the side of the deformation pad 4 close to the clamping plate 2, a surface-attaching layer 42 is fixedly connected. On the side of the clamping plate 2 close to the deformation pad 4, a rough surface-attaching layer 41 adhesively bonded to the surface-attaching layer 42 is fixedly connected. On the side of the deformation pad 4 away from the clamping plate 2, a puncture-proof pad 5 is provided. The puncture-proof pad 5 is made of rubber material, which improves its durability and puncture resistance and is used to protect the deformation pad 4. The design of the puncture-proof pad 5 can effectively reduce the direct extrusion or puncture of the workpiece on the deformation pad 4, greatly reducing the risk of the deformation pad 4 being punctured. On the side of the deformation pad 4 close to the puncture-proof pad 5, a rough surface-attaching layer 51 is fixedly connected. On the side of the puncture-proof pad 5 close to the deformation pad 4, a surface-attaching layer 52 adhesively bonded to the rough surface-attaching layer 51 is fixedly connected. When the hook surface and the rough surface come into contact with each other, they will generate a strong adhesive force, enabling the deformation pad 4 and the puncture-proof pad 5 to be repeatedly pasted and disassembled for maintenance;

[0026] On the side of the clamping plate 2 close to the deformation pad 4, a test paper 6 is fixedly connected. The test paper 6 surrounds the deformation pad 4 on all four sides. The deformation pad 4 is filled with a gas mixture containing gas and chemical substances, mainly for rapid expansion and energy release. Usually, the gas filled in the deformation pad 4 is nitrogen (N2) because nitrogen is relatively stable and inert, not easily causing fire or explosion. In addition, nitrogen does not pose a hazard to the human body. The gas that causes the test paper 6 to change color when it comes into contact with the test paper 6 after the deformation pad 4 leaks is usually nitrate. After the deformation pad 4 leaks, the nitrate in it may react with moisture and oxygen in the air to form nitric acid, which can cause the corresponding test paper 6 to change color, used to indicate the leakage of the deformation pad 4. It can be used in the maintenance and inspection of the deformation pad 4 to quickly detect whether the deformation pad 4 leaks air, enabling the operator to discover and solve problems in a timely manner, avoiding work interruption or unstable workpiece clamping caused by air leakage. Since air leakage may lead to a decrease in clamping force, increasing the risks to workers and equipment in the working environment, by detecting air leakage in a timely manner, potential safety hazards can be reduced, ensuring the safety of the workplace. Discovering and solving the air leakage problem of the deformation pad 4 in a timely manner can avoid downtime and additional costs caused by this during the processing. Moreover, by regularly checking the color change of the test paper 6, the leaking deformation pad 4 can be replaced in a timely manner. The replacement of the deformation pad 4 only requires separating the rough surface from the surface. This avoids workpiece damage or a decline in processing quality caused by air leakage, thus saving maintenance and replacement costs. Therefore, setting the test paper 6 to detect whether the deformation pad 4 leaks air is an effective measure, which helps to improve work efficiency, ensure work safety, and save maintenance costs.

[0027] Working principle and usage process of the present utility model: Place the workpiece on the top of the housing 1. Rotating the turning handle 31 can cause the double-threaded lead screw 32 to rotate, and the rotation of the double-threaded lead screw 32 causes the two driving blocks 33 to move on the outer wall of the double-threaded lead screw 32, so that the two clamping plates 2 fix the workpiece. When the two clamping plates 2 contact the workpiece, the anti-puncture pad 5 first contacts the workpiece, and the deformable anti-puncture pad 5 squeezes the deformation pad 4, and then the gas in the deformation pad 4 pushes the anti-puncture pad 5 to fit more closely to the uneven parts of the workpiece. Through this mechanism, the uneven parts of the workpiece can be fixed more effectively, ensuring that there is no displacement or shaking during the processing, which helps to improve the processing accuracy and efficiency and ensure the stable processing of the workpiece.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
