Description

Technical Field

[0001] The present application relates to the field of production of reinforced steel sheets, and particularly to a fixture for machining reinforced steel sheets on a four-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 of the FPC flexible printed circuit board during use can be reduced.

[0003] After the reinforced steel sheet is initially processed and formed by the die-cutting process, it still needs to be milled and formed by a machine tool. Since the shape of the finally processed and formed reinforced steel sheet is complex, a conventional three-axis machine tool needs to go through multiple processing procedures to complete the processing and forming of the reinforced steel sheet, which is not conducive to improving the production efficiency of the reinforced steel sheet.

[0004] The processing process of the reinforced steel sheet by a four-axis machine tool is somewhat simplified. The clamping device is driven by a power device to carry the reinforced steel sheet and rotate along the workbench of the four-axis machine tool to cooperate with the main spindle tool of the four-axis machine tool to complete the processing process. However, during the process of using the four-axis machine tool to complete the processing of the reinforced steel sheet, the reinforced steel sheet needs to be clamped multiple times. Therefore, the operator needs to spend a lot of clamping time, which is not conducive to improving the production efficiency of the reinforced steel sheet and there is room for improvement. Summary of the Utility Model

[0005] In order to improve the production efficiency of the reinforced steel sheet, the present application provides a fixture for machining the reinforced steel sheet on a four-axis machine tool.

[0006] The fixture for machining the reinforced steel sheet on a four-axis machine tool provided by the present application adopts the following technical solution:

[0007] A fixture for machining the reinforced steel sheet on a four-axis machine tool includes a main frame, a bearing plate, a plurality of material placing plates and a clamping mechanism. The fixed end of the bearing plate is rotatably carried on the main frame, and the free end of the bearing plate is connected to a power device for driving the bearing plate to rotate along the main frame. The plurality of material placing plates are sequentially arranged on the bearing plate along the length direction of the bearing plate. A plurality of clamping positions are provided on the material placing plates for fixing the reinforced steel sheet, and the clamping mechanism is used for clamping the plurality of material placing plates.

[0008] By adopting the above technical solution, the operator fixes the main frame on the workbench of the four-axis machine tool. After the current plane of the reinforcing steel sheet is processed by the cutting tool installed on the main shaft of the four-axis machine tool, the power device drives the bearing plate to carry the clamping mechanism and several material placing plates to rotate along the main frame, realizing the commutation operation of the reinforcing steel sheet, so as to facilitate the four-axis machine tool to complete the processing of the next plane of the reinforcing steel sheet. At the same time, since the number of material placing plates is several and several clamping positions are provided on each material placing plate, the processing requirements of multiple reinforcing steel sheets can be completed simultaneously with one clamping, simplifying the clamping process during the processing of the reinforcing steel sheet and playing a positive guiding role in improving the production efficiency of the reinforcing steel sheet.

[0009] Preferably, the clamping mechanism includes two groups of main clamping components and several groups of common clamping components. The two groups of main clamping components are arranged at both ends of the bearing plate along the length direction. Several groups of common clamping components are sequentially arranged on the bearing plate between two adjacent material placing plates. The two groups of main clamping components are used to clamp one end of the initial material placing plate and the end material placing plate arranged on the bearing plate. Several groups of common clamping components are used to clamp one end of two adjacent material placing plates.

[0010] By adopting the above technical solution, through the cooperation of two groups of main clamping components and several groups of common clamping components, the clamping requirements of several material placing plates are realized, so that several material placing plates can be stably fixed on the bearing plate.

[0011] Preferably, the main clamping component includes a first driving member and a clamping block. The first driving member is arranged on the bearing plate, and the first driving member is used to drive the clamping block to approach / or move away from the bearing plate.

[0012] By adopting the above technical solution, the first driving member drives the clamping block to move along the bearing plate, so as to realize the clamping requirements of the initial material placing plate and the end material placing plate located on the bearing plate. The mechanical structure is simple, easy to maintain, and the clamping force is relatively stable, reducing the probability of the situation that the material placing plate falls off the bearing plate due to insufficient clamping force.

[0013] Preferably, the common clamping component includes a second driving member and a bidirectional clamping plate. The second driving member is arranged on the bearing plate between two adjacent material placing plates, and the second driving member is used to drive the bidirectional clamping plate to clamp one end of two adjacent material placing plates simultaneously.

[0014] By adopting the above technical solution, the second driving member drives the bidirectional clamping plate to move along the main frame, realizing the clamping and releasing of one end of two adjacent material placing plates arranged on the bearing plate.

[0015] Preferably, positioning holes are provided on the material placing plate, positioning pins are provided on the bearing plate, and the positioning pins are inserted into and cooperate with the positioning holes.

[0016] By adopting the above technical solution, when the material placing plate needs to be arranged on the bearing plate, through the guiding cooperation of the positioning hole and the positioning pin, the material placing plate can be quickly and relatively accurately arranged on the bearing plate, reducing the probability that when the material placing plate is arranged on the bearing plate again, the arrangement position of the material placing plate along the bearing plate changes, resulting in a large deviation in the tolerance dimension of the reinforced steel sheet processed by the four-axis machine tool.

[0017] Preferably, support blocks are provided on the bearing plate, and the height of the support blocks is the same as the height of the bearing plate. When the material placing plate is arranged on the bearing plate, the surface of the material placing plate facing the bearing plate abuts against the support blocks.

[0018] By adopting the above technical solution, a certain supporting force is provided for the material placing plate when it is arranged on the bearing plate through the support blocks, reducing the probability that when the tool of the four-axis machine tool processes the reinforced steel sheet, chatter occurs due to the surface where the material placing plate abuts against the bearing plate being in a suspended state.

[0019] Preferably, a holding member is provided on the material placing plate, and the holding member is used for an operator to hold.

[0020] By adopting the above technical solution, the operator can quickly take out the material placing plate along the bearing plate or place the material placing plate on the bearing plate through the holding part, improving the convenience of the operator during operation.

[0021] Preferably, a plurality of waist-shaped grooves are formed in the main frame.

[0022] By adopting the above technical solution, the position of the main frame when it is installed on the workbench of the four-axis machine tool can be adjusted through the waist-shaped grooves, so as to facilitate the adjustment of the tolerance in the horizontal direction of the main frame.

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

[0024] 1. The power device drives the bearing plate, the clamping mechanism and a plurality of material placing plates to rotate along the main frame, realizing the commutation operation of the reinforced steel sheet, so as to facilitate the four-axis machine tool to complete the processing of the next plane of the reinforced steel sheet. At the same time, since the number of material placing plates is several, the processing requirements of multiple reinforced steel sheets can be completed simultaneously with one clamping, simplifying the clamping process during the processing of the reinforced steel sheet, and playing a positive guiding role in improving the production efficiency of the reinforced steel sheet;

[0025] 2. By the guiding cooperation between the positioning holes and the positioning pins, it is beneficial to reduce the probability of the situation where the tolerance dimension deviation of the reinforced steel sheet processed by the four-axis machine tool is relatively large due to the change in the setting position of the material placing plate along the bearing plate when the material placing plate is set on the bearing plate again.

[0026] 3. By providing a certain supporting force for the material placing plate when it is set on the bearing plate through the supporting block, the probability of the situation where chatter occurs when the tool of the four-axis machine tool processes the reinforced steel sheet due to the surface where the material placing plate abuts against the bearing plate being in a suspended state is reduced.

Detailed Description of the Embodiment

[0031] The following Figures 1-3 further describes the present application in detail.

[0032] An embodiment of the present application discloses a fixture for processing a reinforced steel sheet 9 by a four-axis machine tool. Referring to Figure 1 and Figure 2 , a fixture for processing a reinforced steel sheet 9 by a four-axis machine tool includes a main frame 1, a bearing plate 2, a plurality of material placing plates 3, and a clamping mechanism 4. The fixed end of the bearing plate 2 is rotatably carried on the main frame 1, the free end of the bearing plate 2 is connected to a power device, the power device is used to drive the bearing plate 2 to rotate along the main frame 1, the plurality of material placing plates 3 are sequentially arranged on the bearing plate 2 along the length direction of the bearing plate 2, a plurality of clamping positions 31 are provided on the material placing plate 3, the clamping positions 31 are used to fix the reinforced steel sheet 9, and the clamping mechanism 4 is used to clamp the plurality of material placing plates 3.

[0033] Specifically, a support member 5 is installed on the main frame 1. The support member 5 can be a support turntable to carry the fixed end of the carrier plate 2 and rotate along the main frame 1. In this embodiment, the support member 5 is selected as a vertical chuck 51, and the carrier plate 2 is clamped by the jaws of the vertical chuck 51, so that the carrier plate 2 can stably rotate along the vertical chuck 51.

[0034] Correspondingly, the power device can be a servo motor power output device, and the output shaft of the servo motor is connected to the free end of the carrier plate 2 to drive the carrier plate 2 to rotate along the main frame 1. At the same time, the servo motor has the characteristic that the rotation angle is highly controllable, so that the rotation angle of the carrier plate 2 is controllable to cooperate with the four-axis machine tool to complete the processing of the reinforcing steel sheet 9.

[0035] On the other hand, a plurality of clamping positions 31 are provided on the material placing plate 3. The fixing method of the plurality of clamping positions 31 for the reinforcing steel sheet 9 is by bolts, which are existing fixing components, and their specific composition and fixing method will not be elaborated here.

[0036] In addition, a plurality of waist-shaped grooves 11 are provided on the main frame 1. The number of the waist-shaped grooves 11 can be increased or decreased according to actual needs. In this embodiment, the number of the waist-shaped grooves 11 is three groups, and the three groups of waist-shaped grooves 11 are evenly distributed on the main frame 1 along the length direction of the main frame 1. The position of the main frame 1 installed on the workbench of the four-axis machine tool can be adjusted through the waist-shaped grooves 11, so as to facilitate the adjustment of the tolerance in the horizontal direction of the main frame 1.

[0037] Therefore, the implementation principle of a fixture for processing the reinforcing steel sheet 9 of a four-axis machine tool in this application embodiment is as follows: The operator fixes the main frame 1 on the workbench of the four-axis machine tool. When the current plane of the reinforcing steel sheet 9 is processed by the tool installed on the spindle of the four-axis machine tool, the power device drives the carrier plate 2 to carry the clamping mechanism 4 and a plurality of material placing plates 3 to rotate along the main frame 1, realizing the commutation operation of the reinforcing steel sheet 9, so as to facilitate the four-axis machine tool to complete the processing of the next plane of the reinforcing steel sheet 9. At the same time, because the number of the material placing plates 3 is several, and a plurality of clamping positions 31 are provided on each material placing plate 3, the clamping mechanism 4 can complete the processing requirements of multiple reinforcing steel sheets 9 at one time during one clamping, simplifying the clamping process during the processing of the reinforcing steel sheet 9, and playing a positive guiding role in improving the production efficiency of the reinforcing steel sheet 9.

[0038] Refer to Figure 1 and Figure 2, the clamping mechanism 4 includes two groups of main clamping components 41 and several groups of shared clamping components 42. The two groups of main clamping components 41 are arranged at both ends of the bearing plate 2 along the length direction, and several groups of shared clamping components 42 are sequentially arranged on the bearing plate 2 between two adjacent material placing plates 3. The two groups of main clamping components 41 are used to clamp one end of the initial material placing plate 3 and the last material placing plate 3 arranged on the bearing plate 2, and several groups of shared clamping components 42 are used to clamp one end of two adjacent material placing plates 3.

[0039] Specifically, a plurality of placing positions 22 are arranged on the bearing plate 2 along its length direction. The number of placing positions 22 is adapted to the number of material placing plates 3. The placing positions 22 are all used for placing the material placing plates 3. The number of placing positions 22 can be set according to the actual number of material placing plates 3 and the effective working stroke range of the spindle of the four-axis machine tool. In this embodiment, the number of placing positions 22 is set to three to adapt to the current four-axis machine tool.

[0040] Furthermore, the two groups of main clamping components 41 are respectively installed on the bearing plate 2 near one end of the vertical chuck 51 and on the bearing plate 2 near the power device. Since the components of the two groups of main clamping components 41 are the same, the main clamping component 41 near one end of the vertical chuck 51 is taken below for detailed description.

[0041] Refer to Figure 2 and Figure 3 , the main clamping component 41 includes a first driving member 411 and a clamping block 412. The first driving member 411 is arranged on the bearing plate 2, and the first driving member 411 is used to drive the clamping block 412 to approach / or move away from the bearing plate 2.

[0042] Specifically, the first driving member 411 can be a motor screw drive device to meet the clamping requirements of higher precision and greater clamping force. In this embodiment, the first driving member 411 selects the first driving cylinder 6. The first driving cylinder 6 is installed on the surface of the bearing plate 2 facing the main frame 1, and the piston rod of the first driving cylinder 6 movably penetrates through the bearing plate 2 and extends above the bearing plate 2 to enable the piston rod of the first driving cylinder 6 to smoothly contract along the bearing plate 2.

[0043] Furthermore, the external contour of the clamping block 412 is arranged in a cuboid shape and is fixedly connected to the piston rod of the first driving cylinder 6 through bolts. When the material placing plate 3 is placed on the placing position 22, the piston rod of the first driving cylinder 6 can be controlled to contract, so that the clamping block 412 moves towards the material placing plate 3 to achieve the purpose of clamping one end of the material placing plate 3 near the vertical chuck 51.

[0044] Please continue to refer to Figure 1 and Figure 2, the shared clamping assembly 42 includes a second driving member 421 and a two-way clamping plate 422. The second driving member 421 is disposed on the bearing plate 2 between two adjacent material placing plates 3. The second driving member 421 is used to drive the two-way clamping plate 422 to clamp two adjacent material placing plates 3 simultaneously.

[0045] Specifically, since several groups of shared clamping assemblies 42 are disposed on the bearing plate 2 between two material placing plates 3, the number of shared clamping assemblies 42 is one less than the number of placing positions 22. In this embodiment, in order to adapt to three placing positions 22, two groups of shared clamping assemblies 42 are provided. The components of the two groups of shared clamping assemblies 42 are the same. Any one of the two groups will be described in detail below.

[0046] Correspondingly, the second driving member 421 can also be a motor lead screw transmission device to meet the clamping requirements of higher precision and greater clamping force. In this embodiment, the second driving member 421 is a second driving cylinder 7. The second driving cylinder 7 is installed on the bearing plate 2 between two adjacent placing positions 22, and the piston rod of the second driving cylinder 7 movably penetrates through the bearing plate 2 and extends outside the surface of the bearing plate 2 facing away from the main frame 1.

[0047] Meanwhile, the two-way clamping plate 422 is provided with a mounting hole along its geometric center. The two-way clamping plate 422 is fixedly connected to the piston rod of the second driving cylinder 7 through the mounting hole by bolts. Therefore, when the piston rod of the second driving cylinder 7 moves, the two-way clamping plate 422 moves synchronously with the piston rod of the second driving cylinder 7. When the piston rod of the second driving cylinder 7 extends, the two-way clamping plate 422 moves upward in the vertical direction, so as to separate one end of the two material placing plates 3 adjacent to the two-way clamping plate 422 from the two-way clamping plate 422, facilitating the removal of the material placing plate 3 along the placing position 22. When the piston rod of the second driving cylinder 7 contracts, the two-way clamping plate 422 moves downward in the vertical direction, so as to make one end of the two material placing plates 3 adjacent to the second driving cylinder 7 abut against the two-way clamping plate 422, achieving the purpose of clamping the two material placing plates 3.

[0048] Therefore, after an operator sequentially installs several reinforcing steel sheets 9 on the clamping positions 31, the three material placing plates 3 are sequentially placed on the placing positions 22. Subsequently, the first driving cylinder 6 and the second driving cylinder 7 act synchronously. By providing clamping force through the first driving cylinder 6 and the second driving cylinder 7, both ends of the material placing plate 3 are fixed, enabling the material placing plate 3 to be stably placed on the bearing plate 2, and reducing the probability of the situation that the material placing plate 3 is displaced or falls off along the bearing plate 2 when the bearing plate 2 rotates along the main frame 1 or when the four-axis machine tool processes the reinforcing steel sheet 9.

[0049] Refer to Figure 1 and Figure 2 or Figure 3, a positioning hole 32 is provided on the material placing plate 3, and a positioning pin 23 is provided on the bearing plate 2. The positioning pin 23 is inserted and matched with the positioning hole 32.

[0050] Specifically, two positioning holes 32 are provided. The two positioning holes 32 are symmetrically arranged at two edges of the material placing plate 3 along the geometric center of the material placing plate 3. At the same time, two positioning pins 23 are provided. The two positioning pins 23 are symmetrically arranged at two edges of the placing position 22 along the geometric center of the placing position 22. The contours of the two positioning pins 23 are adapted to the contours of the two positioning holes 32.

[0051] Therefore, when the material placing plate 3 needs to be set on the bearing plate 2, through the guiding cooperation between the positioning hole 32 and the positioning pin 23, the material placing plate 3 can be quickly and relatively accurately set on the bearing plate 2, reducing the probability that when the material placing plate 3 is set on the bearing plate 2 again, the setting position of the material placing plate 3 along the bearing plate 2 changes, resulting in a large deviation in the tolerance dimension of the reinforcing steel sheet 9 processed by the four-axis machine tool.

[0052] Refer to Figure 1 and Figure 2 , a support block 21 is provided on the bearing plate 2. The height of the support block 21 is the same as the height of the bearing plate 2. When the material placing plate 3 is set on the bearing plate 2, the surface of the material placing plate 3 facing the bearing plate 2 abuts against the support block 21. The support block 21 provides a certain supporting force when the material placing plate 3 is set on the bearing plate 2, reducing the probability that when the surface where the material placing plate 3 abuts against the bearing plate 2 is in a suspended state, the cutting tool of the four-axis machine tool vibrates during the processing of the reinforcing steel sheet 9.

[0053] Refer to Figure 1 , a holding member 33 is provided on the material placing plate 3. The holding member 33 is used for an operator to hold.

[0054] Specifically, the holding member 33 can be a holding ring for the convenience of the operator to hold. In this embodiment, the holding member 33 is set as a holding handle. The operator can quickly take out the material placing plate 3 along the bearing plate 2 or place the material placing plate 3 on the bearing plate 2 through the holding part, improving the convenience of the operator during operation.

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