Description

Technical Field

[0001] This application relates to the field of reinforced steel sheet processing, and particularly to a fixture for processing reinforced steel sheets used in a three-axis machine tool. Background Art

[0002] The main purpose of the reinforced steel sheet is to increase the thickness and hardness of a specific area of the FPC flexible printed circuit board. By attaching the reinforced steel sheet to a certain position or area of the FPC, the mechanical strength of the FPC flexible printed circuit board can be effectively enhanced, and the probability of bending or deformation occurring during the use of the FPC flexible printed circuit board can be reduced.

[0003] During the production process of the reinforced steel sheet, it is necessary to die-cut a glue product that meets the preset requirements through a stamping die, then attach the die-cut glue product to a steel strip, and then use a punch to punch holes and shape the outer contour of the steel strip with the attached glue product to achieve mass production of reinforced steel sheets that meet the design requirements.

[0004] After the production of the reinforced steel sheet is completed, it is also necessary to cut and trim the shaped reinforced steel sheet through computer numerical control (CNC). Due to the large number of reinforced steel sheets, operators need to spend a lot of time clamping the reinforced steel sheets on the workbench of the machine tool, resulting in a reduction in the production efficiency of the reinforced steel sheets, and there is room for improvement. Utility Model Content

[0005] In order to improve the production efficiency of the reinforced steel sheet, this application provides a fixture for processing reinforced steel sheets used in a three-axis machine tool.

[0006] The fixture for processing reinforced steel sheets used in a three-axis machine tool provided by this application adopts the following technical solution:

[0007] A fixture for processing reinforced steel sheets used in a three-axis machine tool includes a main frame, several groups of clamping mechanisms, and a material placement plate. A plurality of placement areas are provided on the material placement plate, and all of the plurality of placement areas are used to fix the reinforced steel sheets. Several groups of the clamping mechanisms are sequentially arranged on the main frame, and several groups of the clamping mechanisms are used to clamp the material placement plate. The clamping mechanism includes two groups of clamping components and two groups of driving members. The two groups of clamping components are oppositely arranged along the width direction of the main frame, and the two groups of driving members are arranged on the main frame along the width direction of the main frame. The two groups of clamping components cooperate to clamp the material placement plate, and the driving member is used to drive the clamping component to act.

[0008] By adopting the above technical solution, the operator orderly places the reinforcing steel sheets to be processed on the material placing plate, and then sequentially places the material placing plate on the clamping mechanism. The clamping mechanism clamps the material placing plate. When the material placing plate is set on the clamping mechanism, the driving member drives the clamping assembly to clamp the material placing plate. The three-axis machine tool processes the reinforcing steel sheets on the material placing plate one by one. Thus, through the above process, several reinforcing steel sheets can be processed simultaneously by clamping the material placing plate once, without the need to frequently clamp the reinforcing steel sheets in batches, which plays a positive guiding role in improving the processing efficiency of the reinforcing steel sheets.

[0009] Preferably, the clamping assembly includes a clamping block and a connecting member. The free end of the clamping block is used to clamp the material placing plate. The driving member is rotatably connected to the fixed end of the clamping block. One end of the connecting member is rotatably connected to the main frame, and the other end of the connecting member is rotatably connected to the clamping block. The driving member is used to drive the clamping block to rotate along the connecting member to clamp or release the material placing plate.

[0010] By adopting the above technical solution, the driving member drives the clamping block to rotate along the connecting member. When the driving member drives the clamping block to move towards the main frame, the material placing plate is clamped; when the driving member drives the clamping block to move away from the main frame, the clamping of the material placing plate is released. The mechanical structure is simple, easy to maintain, and highly practical.

[0011] Preferably, a limiting groove is formed at the fixed end of the clamping block, and the driving end of the driving member is in transitional fit with the limiting groove.

[0012] By adopting the above technical solution, the limiting groove limits the path of the driving end of the driving member when driving the clamping block to move, which is beneficial to reducing the yaw of the clamping block when clamping or releasing the material placing plate, making the clamping force exerted by the free end of the clamping block on the material placing plate in a stable state, and reducing the probability of the situation that the material placing plate changes or loosens along the fixed position of the main frame during the processing of the reinforcing steel sheets by the three-axis machine tool due to insufficient clamping force exerted by the clamping block on the material placing plate.

[0013] Preferably, a pin shaft is inserted through the clamping block. The pin shaft is fixedly connected to the clamping block. The pin shaft movably penetrates through the connecting member, and a snap ring groove is formed at the inserted end of the pin shaft.

[0014] By adopting the above technical solution, the pin shaft realizes the movable connection between the clamping block and the connecting member, enabling the clamping block to rotate smoothly along the connecting member. At the same time, the snap ring can be used to fix the pin shaft through the snap ring groove, reducing the probability of the pin shaft falling off along the connecting member, and also facilitating the maintenance or replacement of the pin shaft, the connecting member, and / or the clamping block.

[0015] Preferably, a positioning member is provided on the main frame. The positioning member includes a positioning shaft, and positioning holes are formed in the material placing plate. When the material placing plate is placed on the main frame, the positioning holes are inserted and matched with the positioning shaft.

[0016] By adopting the above technical solution, after several reinforcing steel sheets on the current material placing plate are processed, it is necessary to take out the material placing plate along the current clamping assembly and replace it with the next material placing plate on which the reinforcing steel sheets to be processed are placed. Through the cooperation of the positioning shaft and the positioning holes, the position of any material placing plate on the main frame can be in a relatively fixed state, which is beneficial to reducing the time required for secondary tolerance calibration due to the change of the installation position of the material placing plate on the main frame, and plays a positive guiding role in improving the processing accuracy of the reinforcing steel sheets.

[0017] Preferably, shock-absorbing members are provided on the main frame on both sides of the positioning shaft. When the material placing plate is placed on the main frame, the material placing plate is in contact with the shock-absorbing members.

[0018] By adopting the above technical solution, when the main shaft of the three-axis machine tool is working, the cutting tool will be in direct contact with the reinforcing steel sheet, so certain vibrations will be generated. Part of the vibration force is transmitted to the main frame through the material placing plate, causing a slight position shift of the material placing plate along the main frame. Therefore, by using the shock-absorbing members to reduce the vibration force transmitted from the material placing plate to the main frame, it is beneficial to reduce the position shift amount of the material placing plate along the main frame, and further plays a positive guiding role in improving the processing accuracy of the reinforcing steel sheets.

[0019] Preferably, holding portions are provided at both ends of the material placing plate in the length direction. The holding portions are used for an operator to hold.

[0020] By adopting the above technical solution, through the holding portions, it is convenient for the operator to take out the material placing plate with the reinforcing steel sheets along the main frame, or place the material placing plate with the reinforcing steel sheets on the main frame, improving the overall convenience.

[0021] Preferably, a plurality of groups of waist-shaped grooves are formed in the main frame. The plurality of groups of waist-shaped grooves are evenly distributed on the main frame along the length direction of the main frame.

[0022] By adopting the above technical solution, the installation position of the main frame along the three-axis machine tool can be adjusted through the waist-shaped grooves, and it is also convenient to replace the main frames of different sizes / specifications.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. It is possible to process several reinforcing steel sheets at the same time with one clamping of the material placing plate, without frequently clamping the reinforcing steel sheets in batches, which plays a positive guiding role in improving the processing efficiency of the reinforcing steel sheets;

[0025] 2. The driving member drives the clamping block to rotate along the connecting member. When the driving member drives the clamping block to move towards the main frame, the feeding plate is clamped; when the driving member drives the clamping block to move away from the main frame, the clamping of the feeding plate is released. The mechanical structure is simple, easy to maintain, and highly practical.

[0026] 3. Through the cooperation of the positioning shaft and the positioning hole, the position of any feeding plate on the main frame can be relatively fixed, which is beneficial to reducing the time required for secondary tolerance calibration due to the change in the position of the feeding plate installed on the main frame.

Detailed Description of the Embodiment

[0031] The following will further describe the present application in detail Figures 1-3 with reference to the accompanying drawings.

[0032] An embodiment of the present application discloses a fixture for processing reinforced steel sheets used in a three-axis machine tool. Refer to Figure 1 and Figure 2, A fixture for processing reinforced steel sheets on a three-axis machine tool includes a main frame 1, several groups of clamping mechanisms 2, and a material placement plate 3. The material placement plate 3 is provided with several placement areas 31, and several placement areas 31 are all used to fix the reinforced steel sheets. Several groups of clamping mechanisms 2 are sequentially arranged on the main frame 1, and several groups of clamping mechanisms 2 are used to clamp the material placement plate 3. The clamping mechanism 2 includes two groups of clamping components 21 and two groups of driving members 22. The two groups of clamping components 21 are arranged oppositely along the width direction of the main frame 1, and the two groups of driving members 22 are arranged on the main frame 1 along the width direction of the main frame 1. The two groups of clamping components 21 cooperate to clamp the material placement plate 3, and the driving member 22 is used to drive the clamping component 21 to act.

[0033] Specifically, the number of placement areas 31 can be changed according to actual production requirements. Since the number is relatively large, its number is not limited here. When the operator sequentially installs the reinforced steel sheets into the placement areas 31, the locking component of the material placement plate 3 locks several reinforced steel sheets, so that the reinforced steel sheets are stably fixed on the material placement plate 3, reducing the probability of the reinforced steel sheets falling off the material placement plate 3 when the main shaft of the three-axis machine tool processes the reinforced steel sheets. It is an existing fixing component, and its specific locking method is not described in detail here.

[0034] Furthermore, the number of clamping mechanisms 2 can be changed according to the working stroke of the three-axis machine tool. In this embodiment, according to the working conditions of the existing three-axis machine tool, three groups of clamping mechanisms 2 are provided. The three groups of clamping mechanisms 2 are evenly distributed on the main frame 1 along the length direction of the main frame 1. Therefore, the three groups of clamping mechanisms 2 can simultaneously clamp three groups of material placement plates 3. At this time, the main shaft of the three-axis machine tool sequentially completes the processing of the reinforced steel sheets on the material placement plates 3 along the length direction of the main frame 1, greatly reducing the time required for clamping.

[0035] Correspondingly, in this embodiment, the components of the two groups of clamping components 21 and the two groups of driving members 22, and the two groups of clamping components 21 and the two groups of driving members 22 are symmetrically arranged at the edges of the main frame 1 along the geometric center in the width direction of the main frame 1. Since the components and installation methods of the two groups of clamping components 21 and the two groups of driving members 22 are the same, any one of the clamping components 21 and the driving member 22 is taken here to explain it in detail.

[0036] Refer to Figure 2 and Figure 3 , the clamping component 21 includes a clamping block 211 and a connecting member 212. The free end of the clamping block 211 is used to clamp the material placement plate 3. The driving member 22 is rotatably connected to the fixed end of the clamping block 211. One end of the connecting member 212 is rotatably connected to the main frame 1, and the other end of the connecting member 212 is rotatably connected to the clamping block 211. The driving member 22 is used to drive the clamping block 211 to rotate along the connecting member 212 to clamp or release the material placement plate 3.

[0037] Specifically, the driving member 22 can be a motor screw structure to meet the clamping requirements with relatively high clamping force. In this embodiment, the driving member 22 is set as a driving cylinder 221.

[0038] Furthermore, a bearing platform 11 is installed on the main frame 1. The bearing platform 11 is used to bear the material placing plate 3. The cross-sectional shape of the bearing platform 11 is U-shaped and is fixed to the main frame 1 by bolts. At the same time, the main frame 1 is provided with an avoidance hole 13 penetrating in the thickness direction. The driving cylinder 221 is installed on the surface of the bearing platform 11 facing the main frame 1, and the piston rod of the driving cylinder 221 movably penetrates through the avoidance hole 13, so that the piston rod can stretch along the avoidance hole 13 without interference.

[0039] At the same time, an installation platform 12 is installed on the driving cylinder 221. The installation platform 12 is located on one side of the piston rod of the driving cylinder 221. At the same time, one end of the connecting member 212 is rotatably connected to the installation platform 12. When the driving cylinder 221 is installed on the bearing platform 11, the installation platform 12 is located between the driving cylinder 221 and the bearing platform 11, so that the installation platform 12 can be stably locked on the driving cylinder 221.

[0040] Correspondingly, a pin shaft 5 penetrates through the clamping block 211. The pin shaft 5 is fixedly connected to the clamping block 211. The pin shaft 5 movably penetrates through the connecting member 212, and a snap ring groove 51 is formed at the inserted end of the pin shaft 5. When the clamping block 211 is connected to the connecting member 212 through the pin shaft 5, the clamping block 211 can smoothly rotate along the connecting member 212 through the cooperation of the snap ring groove 51 and the snap ring. At the same time, the pin shaft 5 can be fixed by the snap ring through the snap ring groove 51, reducing the probability of the pin shaft 5 falling off along the connecting member 212. At the same time, it is also convenient for maintaining or replacing the pin shaft 5, the connecting member 212 and / or the clamping block 211.

[0041] Therefore, the piston rod of the driving cylinder 221 drives the clamping block 211 to rotate. When the piston rod of the driving cylinder 221 extends, the clamping block 211 rotates towards the upper surface of the main frame 1 with the pin shaft 5 as the fulcrum to clamp the material placing plate 3; when the piston rod of the driving cylinder 221 contracts, the clamping block 211 moves away from the upper surface of the main frame 1 with the pin shaft 5 as the fulcrum to release the clamping of the material placing plate 3. The mechanical structure is simple, and the clamping force applied to the material placing plate 3 by the clamping block 211 is relatively stable, with high practicability.

[0042] Refer to Figure 2 and Figure 3 , a limiting groove 4 is formed at the fixed end of the clamping block 211, and the driving end of the driving member 22 is in transitional fit with the limiting groove 4.

[0043] Specifically, the contour of the limiting groove 4 is adapted to the shape of the piston rod of the driving cylinder 221, and the movable connection between the clamping block 211 and the piston rod of the driving cylinder 221 is realized through a pin.

[0044] Therefore, by limiting the path of the driving end of the driving member 22 through the limiting groove 4 when driving the clamping block 211 to move, it is beneficial to reduce the yaw of the clamping block 211 when clamping or releasing the placing plate 3, so that the clamping force applied by the free end of the clamping block 211 to the placing plate 3 is in a stable state, and reduce the probability of the situation that the placing plate 3 changes or loosens along the fixed position of the main frame 1 during the processing of the reinforcing steel sheet by the three-axis machine tool due to insufficient clamping force applied by the clamping block 211 to the placing plate 3.

[0045] Refer to Figure 2 and Figure 3 , a positioning member 6 is provided on the main frame 1. The positioning member 6 includes a mounting seat 61 and a positioning shaft 62. A positioning hole 7 is formed on the placing plate 3. When the placing plate 3 is placed on the main frame 1, the positioning hole 7 is inserted and matched with the positioning shaft 62.

[0046] Specifically, the outer contour of the mounting seat 61 is arranged in a cuboid shape. The mounting seat 61 is fixed to the surface of the bearing platform 11 facing the main frame 1 by bolts. The outer contour of the positioning shaft 62 is arranged in a cylindrical shape. The positioning shaft 62 is fixedly connected to the mounting seat 61 along the geometric center of the mounting seat 61, and the positioning shaft 62 penetrates through the bearing platform 11 along the thickness direction of the bearing platform 11 and extends to the upper surface of the bearing platform 11. At this time, the positioning shaft 62 is located below the free end of the clamping block 211.

[0047] Therefore, after several reinforcing steel sheets on the current placing plate 3 are processed, it is necessary to take out the placing plate 3 along the current clamping assembly 21 and replace it with the next placing plate 3 on which the reinforcing steel sheet to be processed is placed. Through the cooperation of the positioning shaft 62 and the positioning hole 7, the position of any placing plate 3 on the main frame 1 can be in a relatively fixed state, which is beneficial to reducing the time required for secondary tolerance calibration due to the change of the position of the placing plate 3 installed on the main frame 1, and plays a positive guiding role in improving the processing accuracy of the reinforcing steel sheet.

[0048] Refer to Figure 2 and Figure 3 , shock-absorbing members 8 are arranged on the main frame 1 on both sides of the positioning shaft 62. When the placing plate 3 is arranged on the main frame 1, the placing plate 3 is in contact with the shock-absorbing members 8.

[0049] Specifically, the shock-absorbing members 8 can be rubber pads or buffer cotton. In this embodiment, the shock-absorbing members 8 are set as silicone shock-absorbing pads. Since the main shaft of the three-axis machine tool is in operation, the cutting tool will be in direct contact with the reinforcing steel sheet, so certain vibrations will be generated. Part of the vibration force is transmitted to the main frame 1 through the placing plate 3, causing a slight position offset of the placing plate 3 along the main frame 1. Therefore, by reducing the vibration force transmitted from the placing plate 3 to the main frame 1 through the shock-absorbing members 8, it is beneficial to reduce the position offset amount of the placing plate 3 along the main frame 1, and further plays a positive guiding role in improving the processing accuracy of the reinforcing steel sheet.

[0050] Reference Figure 2 and Figure 3 At both ends of the material placing plate 3 along the length direction, there are provided holding parts 9 for an operator to hold.

[0051] Specifically, the holding part 9 can be a holding ring. In this embodiment, the holding part 9 is set as a holding handle 91. Through the holding handle 91, it is convenient for the operator to take out the material placing plate 3 with the reinforcing steel sheet placed thereon from the main frame 1, or place the material placing plate 3 with the reinforcing steel sheet placed thereon on the main frame 1, improving the overall convenience.

[0052] Reference Figure 2 and Figure 3 On the main frame 1, there are provided several groups of waist-shaped grooves 10, and several groups of waist-shaped grooves 10 are evenly distributed on the main frame 1 along the length direction of the main frame 1.

[0053] Specifically, the number of the waist-shaped grooves 10 can be three groups, four groups, five groups, etc. In this embodiment, there are two groups of waist-shaped grooves 10. The two groups of waist-shaped grooves 10 are symmetrically arranged on the main frame 1 along the geometric center of the length of the main frame 1. Through the waist-shaped grooves 10, the installation position of the main frame 1 along the three-axis machine tool can be adjusted, so that the effective stroke of the three-axis machine tool can be utilized to the maximum extent, and at the same time, it is also convenient to replace the main frame 1 of different sizes / specifications.

[0054] The implementation principle of a fixture for processing reinforcing steel sheets of a three-axis machine tool in an embodiment of the present application is as follows: The operator orderly places the reinforcing steel sheets to be processed on the material placing plate 3, and then sequentially places the material placing plate 3 on the clamping mechanism 2. The clamping mechanism 2 clamps the material placing plate 3. When the material placing plate 3 is arranged on the clamping mechanism 2, the driving member 22 drives the clamping assembly 21 to clamp the material placing plate 3, and the three-axis machine tool processes the reinforcing steel sheets on the material placing plate 3 one by one. Thus, through the above process, several reinforcing steel sheets can be processed simultaneously by clamping the material placing plate 3 once, without frequently clamping the reinforcing steel sheets in batches, which plays a positive guiding role in improving the processing efficiency of the reinforcing steel sheets.

[0055] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
