Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel coil cutting, in particular to a clamp for laser cutting of stainless steel coils. Background Art

[0002] Stainless steel coil is also called coil, coil, plate, plate coil. Stainless steel coil refers to the finished coil made of stainless steel sheet. Stainless steel sheet is made of iron and its alloy as the main raw material, and chromium, nickel, molybdenum and other elements are added, and appropriate rare earth, etc. elements are added to prevent iron from chemically reacting with oxygen in the air to produce rust. Stainless steel coil has the characteristics of not easy to oxidize and corrosion resistance, and is widely used in construction, manufacturing and other fields. In the process of further processing and use, laser cutting devices will be used to cut stainless steel sheets as needed.

[0003] When conventional stainless steel coils are cut by laser, the fixture itself limits and fixes the steel plate. However, since laser cutting uses high temperature to melt the structural surface of the steel plate, as the cutting proceeds, the previously melted parts may become structurally connected due to the structural fixation of the fixture, resulting in incomplete cutting and affecting the effectiveness of the processing operation.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a fixture for laser cutting of stainless steel coils is proposed. Utility Model Content

[0005] The utility model aims to provide a fixture for laser cutting of stainless steel coils to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamp for laser cutting of stainless steel coils, comprising a device frame and a clamping roller assembly, a stainless steel coil body is mounted at one end of the device frame, the clamping roller assembly is horizontally mounted in the middle of the device frame, and one end of the clamping roller assembly is connected to an adjusting seat group, and the end of the clamping roller assembly away from the adjusting seat group is connected to an auxiliary slide, the clamping roller assembly comprises a driving motor, a rotating roller, a transmission sleeve, a clamping block and a sliding seat, the power output end of the driving motor is connected to the rotating roller through a coupling, and the middle part of the rotating roller is symmetrically sleeved with a transmission sleeve, and clamping blocks are installed at both ends of the rotating roller, and a sliding seat is installed at the end of the rotating roller away from the driving motor.

[0007] Furthermore, the device frame includes a support frame, a rotating shaft frame, a bidirectional screw and a servo motor, a rotating shaft frame is symmetrically installed at one end of the support frame, and a bidirectional screw is horizontally installed on the top of one side of the support frame, and a servo motor is installed at one end of the bidirectional screw through a coupling.

[0008] Furthermore, the rotating shaft frame provides the stainless steel coil body with axial rotational activity in the horizontal direction, the bidirectional screw and the support frame are parallel to each other, and the clamping roller assembly, the adjustment seat group and the auxiliary slide are symmetrically installed at the front and rear ends of the bidirectional screw.

[0009] Furthermore, the clamping roller assembly is symmetrically connected to one side of the adjustment seat assembly, and the servo motor is slidably connected to the auxiliary slide, and the auxiliary slide is slidably connected to the support frame.

[0010] Furthermore, the transmission sleeve is made of rubber material, and the transmission sleeve is fixedly sleeved on the surface of the rotating roller, and the rotating roller passes through the middle of the clamping block, and the clamping block and the rotating roller are connected by a bearing structure, and the sliding seat and the support frame are slidably connected.

[0011] Furthermore, the adjustment seat group includes a movable seat, a fixed frame, a direct drive motor and a bidirectional screw. One side of the movable seat is vertically connected to the fixed frame, and the direct drive motor is installed on the top of the fixed frame, and the bottom power output end of the direct drive motor is connected to the bidirectional screw through a coupling.

[0012] Furthermore, the movable seat is threadedly connected to the bidirectional lead screw, and the movable seat is slidably connected to the support frame.

[0013] Furthermore, the bidirectional screw rod vertically penetrates the middle part of the sliding seat, and the sliding seat and the bidirectional screw rod are threadedly connected.

[0014] The utility model provides a fixture for laser cutting of stainless steel coils, which has the following beneficial effects:

[0015] 1. The utility model drives the rotating roller connected to its power output end to rotate axially in the horizontal direction through the driving motor, so that the transmission sleeve installed on the middle section can rotate synchronously. In this way, by using the above structure, the middle steel plate can be rolled and transmitted under the cooperative rotation of the clamping roller assembly symmetrically arranged up and down, thereby playing a role of assisting transportation. The bidirectional screw rod connected to its power output end at the bottom thereof is driven by the direct drive motor to rotate axially in the vertical direction, thereby driving the entire clamping roller assembly connected to it through the sliding seat to translate vertically up and down. By using the above structure, the clamping blocks arranged at the left and right ends of the rotating roller can be displaced synchronously. Since the clamping roller assembly is symmetrically connected to the two ends of the bidirectional screw rod up and down, the steel plate can be clamped up and down in this way, so as to facilitate the subsequent laser cutting device to cut the steel plate. Through the mutual cooperation of the hybrid adjustment seat group of the clamping roller assembly, the steel plate can be effectively clamped stably while providing it with a structural function of transportation, thereby ensuring the practicality of the entire device.

[0016] 2. The utility model is characterized in that a direct-drive motor and a bidirectional lead screw are installed on the top of one side of the support frame. When the direct-drive motor drives the bidirectional lead screw connected to its power output end to perform axial rotation in the horizontal direction, the adjusting seat group which is threadedly connected and slidably connected to the bidirectional lead screw and the support frame by the movable seat will drive the clamping roller assembly connected thereto to move back and forth in the horizontal direction. At the same time, since the clamping roller assembly and the adjusting seat group are symmetrically connected to the two ends of the bidirectional lead screw front and back, the use of the above structure can assist the laser cutting device to make appropriate adjustments within a certain range according to the cutting size and cutting range. On the one hand, it can effectively ensure the structural stability of the cut steel plate. On the other hand, the cooperation of the above structure can also ensure that the cutting area is avoided from bending as much as possible, and plays a structural role in clamping and tightening the steel plate. By utilizing the tightening effect, it can provide pulling force to both sides while cutting the steel plate, assist in separating the cut steel plate, avoid connection of the fuse part, and further ensure the accuracy of the cutting process.

[0025] like Figures 1 to 5As shown, the device frame 1 includes a support frame 101, a rotating shaft frame 102, a bidirectional screw 103 and a servo motor 104. The rotating shaft frame 102 is symmetrically installed at one end of the support frame 101, and a bidirectional screw 103 is horizontally installed on the top of one side of the support frame 101, and a servo motor 104 is installed on one end of the bidirectional screw 103 through a coupling.
