Description

Technical Field

[0001] This utility model relates to the field of double-sided clamping machine technology, and specifically to a double-sided clamping machine device. Background Technology

[0002] A double-sided clamping machine is a specially designed mechanical device used to apply clamping forces from both sides of a material during processing, inspection, or assembly to ensure material stability and accuracy. This device is typically equipped with a precision clamping mechanism and adjustment system, allowing for adjustments to clamping force, position, and angle according to different application requirements. Double-sided clamping machines are widely used in various industrial sectors, such as automotive manufacturing, aerospace, and electronics manufacturing. In these fields, they effectively improve production efficiency, reduce production costs, and enhance product quality. With continuous technological advancements and expanding application areas, double-sided clamping machines will play an even more important role in the future.

[0003] However, although traditional double-sided clamping machines can provide uniform and stable clamping force during processing, effectively reducing material deformation and displacement, and thus improving processing accuracy and efficiency, they still have some limitations. Traditional double-sided clamping machines often lack sufficient flexibility and adjustability, and cannot be precisely adjusted according to the size, thickness and shape of the material. This means that the device often cannot perfectly adapt to the clamping requirements of different shapes, sizes or materials.

[0004] Chinese patent document CN212717509U discloses a clamping device comprising a fixed plate, a connecting plate, a guide plate, and a movable support plate. The two ends of the connecting plate are respectively connected to the top ends of the fixed plate and the guide plate, forming an inverted U-shaped structure with an open bottom. The guide plate has elongated guide holes along its length. The rear end of the movable support plate is engaged in the elongated guide holes and can slide along them. The head end face of the movable support plate corresponds to the inner plate face of the fixed plate to clamp an object. A pushing block is connected to the rear end face of the movable support plate. The angle between the guide plate and the fixed plate is 15–45 degrees, and the angle between the head of the movable support plate and the fixed plate is 45–90 degrees. However, the following defects still exist in its implementation:

[0005] While the device described in the aforementioned documents is convenient to operate, saves time and effort, and is suitable for clamping objects of various widths with a stable grip, it cannot make precise adjustments based on the size, thickness, and shape of the material, thus preventing the device from fixing materials of different sizes. Utility Model Content

[0006] The purpose of this invention is to provide a double-sided clamping machine device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A double-sided clamping machine includes a support plate; the lower end of the support plate is fixedly connected to four legs; the upper end of the support plate has a groove extending from the upper end to the lower end; the upper end of the support plate is symmetrically fixedly connected to a base; the upper parts of the two bases are symmetrically slidably connected to a support structure; the upper parts of the support structures are slidably connected to a clamping structure; the clamping structures are symmetrically fixedly connected to a driving structure; the upper parts of the support structures are fixedly connected to an electric push rod; the lower parts of the two support structures are jointly provided with a moving structure for driving the two support structures to move.

[0009] A further improvement of this utility model is that the base is T-shaped.

[0010] The above technical solution features a T-shaped base, which provides more stable support during operation. Its unique T-shaped structure increases the contact area between the base and other parts of the device, thereby reducing displacement or shaking caused by vibration or external forces and further ensuring the stability of the material during processing.

[0011] A further improvement of the present invention is that the supporting structure includes a horizontal plate, a connecting block 1 is symmetrically fixedly connected to the lower end of the horizontal plate, the inner cavity of the connecting block 1 on the same side is slidably connected to the outer surface of the base, the two connecting blocks 1 are fixedly connected to a connecting plate 1 on opposite sides, a connecting block 2 is symmetrically fixedly connected to the upper end of the horizontal plate, a top plate is fixedly connected to the upper end of the two connecting blocks 2, the upper end of the top plate on the same side is fixedly connected to the lower end of the electric push rod, and the output end of the electric push rod extends through the upper end of the top plate to the lower part.

[0012] By adopting the above technical solution, the position of the connecting block 1 can be limited when the connecting block 1 moves by cooperating with the base, so as to prevent the connecting block 1 from deviating from the trajectory when it moves, thereby affecting the clamping accuracy of the device.

[0013] A further improvement of the present invention is that the clamping structure includes a second connecting plate and a third connecting plate. The outer surfaces of the second connecting plate and the third connecting plate on the same side slide in the inner cavity of the second connecting plate. A rubber block is fixedly connected to one side of the second connecting plate and the third connecting plate. A sliding groove is symmetrically opened at the upper end of the third connecting plate, extending from the upper end of the third connecting plate to the lower part. The output end of the electric push rod on the same side is fixedly connected to the upper end of the second connecting plate.

[0014] The above technical solution involves two rubber blocks, one of which is made of rubber material. Due to the excellent elasticity and flexibility of rubber material, the two rubber blocks can fit tightly against the surface of the material, achieving a stable fixing effect. At the same time, the anti-slip properties of rubber also enhance the stability of the fixation, effectively preventing the material from shifting or sliding during processing. Moreover, rubber material also has good shock absorption and cushioning effects. During processing, machines or tools may impact or vibrate the material, and the rubber blocks made of rubber material can effectively absorb these impacts and vibrations, protecting the material from damage.

[0015] A further improvement of this utility model is that: several anti-slip patterns are provided on the opposing surfaces of the two rubber blocks on the same side.

[0016] By adopting the above technical solution, several anti-slip patterns are formed on one side of the rubber block, which can significantly enhance the friction between the rubber block and the material. This ensures that the material can be stably fixed between the rubber blocks during processing, preventing the material from sliding or shifting due to vibration or external force. Moreover, the anti-slip patterns not only enhance the clamping effect, but also disperse the stress generated during clamping to a certain extent, reducing wear on the rubber block. This helps to extend the service life of the rubber block and reduce maintenance costs.

[0017] A further improvement of the present invention is that the driving structure includes a housing, the side of the housing near the second connecting block is fixedly connected to the second connecting block, a gear is rotatably connected to the inner cavity of the housing, a rack is meshed with the outer surface of the gear near the second connecting block, the upper end of the rack is fixedly connected to the lower end of the second connecting plate, a rack is meshed with the outer surface of the gear away from the second connecting block, and the lower end of the rack is fixedly connected to the upper end of the third connecting plate.

[0018] In the above technical solution, the gear meshes with adjacent racks 1 and 2, and rack 2 is fixedly connected to connecting plate 2, while rack 1 is fixedly connected to connecting plate 3. Thus, when connecting plate 2 moves, it drives rack 2 to mesh with the gear, thereby driving the gear to rotate. Then, the gear meshes with rack 1, driving rack 1 to move. Finally, rack 1 drives connecting plate 3 to move, allowing connecting plate 2 and connecting plate 3 to clamp materials of different thicknesses.

[0019] A further improvement of the present invention is that the movable structure includes a support block and two pulleys. A belt is wound around the outer surface of the two pulleys. The pulley located on the lower side is rotatably connected to the support block. The upper end of the support block is fixedly connected to the lower end of the support plate. A bidirectional lead screw is fixedly connected to the inner cavity of the pulley located on the upper side. The bidirectional lead screw is threadedly connected to a connecting plate. A motor is fixedly connected to one end of the pulley located on the lower side. The upper part of the motor is fixedly connected to the lower end of the support plate.

[0020] Using the above technical solution, the motor output drives the lower pulley to rotate, and then the belt and the two pulleys work together to drive the upper pulley to rotate. The upper pulley drives the bidirectional lead screw to rotate, which in turn drives the two connecting plates to move, thus enabling the device to clamp materials of different lengths.

[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0022] 1. This utility model provides a double-sided clamping machine device. The moving structure can drive two supporting structures to move, thereby allowing the device to adjust its position according to the length of the material. Through the cooperation of the driving structure and the clamping structure, the clamping structure can fix materials of different thicknesses, thereby improving the flexibility and adjustability of the device, and enabling it to be precisely adjusted according to the size, thickness and shape of the material.

[0023] 2. This utility model provides a double-sided clamping machine device. Since the first rubber block is made of rubber material and has anti-slip texture on one side, it not only allows the two rubber blocks to fit tightly against the surface of the material, achieving a stable fixing effect, but also enhances the stability of the fixing due to the anti-slip properties of the rubber, effectively preventing the material from shifting or sliding during processing. In addition, the first rubber block can effectively absorb the impact and vibration generated during material processing, protecting the material from damage. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to embodiments:

[0033] Example 1

[0034] like Figure 1-6 As shown, this utility model provides a double-sided clamping machine device, including a support plate 1; the lower end of the support plate 1 is fixedly connected to the four sides of the support plate 1 with support legs 2; the upper end of the support plate 1 has a sliding groove 11 that extends from the upper end of the support plate 1 to the lower end; the upper end of the support plate 1 is symmetrically fixedly connected to the base 3; the upper parts of the two bases 3 are symmetrically slidably connected to the support structure 4; the upper parts of the support structure 4 are slidably connected to the clamping structure 6; the clamping structure 6 is symmetrically fixedly connected to the driving structure 5; the upper parts of the support structure 4 are fixedly connected to the electric push rod 7; the lower parts of the two support structures 4 are jointly provided with a moving structure 8, which is used to drive the two support structures 4 to move.

[0035] In this embodiment, the support plate 1 supports and connects the device, the support legs 2 adjust the height of the device, and the base 3 limits the movement of the two support structures 4 to prevent them from derailing during movement. The drive structure 5 and the clamping structure 6 work together to clamp and support materials of different thicknesses. The electric push rod 7 provides power for the movement of the clamping structure 6, and the moving structure 8 drives the two support structures 4 to move, thus enabling the device to clamp and support materials of different lengths.

[0036] Example 2

[0037] like Figure 6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the movable structure 8 includes a support block 81 and two pulleys 82. A belt 83 is wound around the outer surface of the two pulleys 82. The pulley 82 located on the lower side is rotatably connected to the support block 81. The upper end of the support block 81 is fixedly connected to the lower end of the support plate 1. A bidirectional lead screw 84 is fixedly connected to the inner cavity of the pulley 82 located on the upper side. The bidirectional lead screw 84 is threadedly connected to the connecting plate 42. A motor 85 is fixedly connected to one end of the pulley 82 located on the lower side. The upper part of the motor 85 is fixedly connected to the lower end of the support plate 1.

[0038] In this embodiment, by running the motor 85, the output end of the motor 85 drives the pulley 82 located on the lower side to rotate. Then, by cooperating with the pulley 82 and the belt 83, the pulley 82 located on the upper side can be driven to rotate. Then, the pulley 82 can drive the bidirectional lead screw 84 to rotate. Then, the bidirectional lead screw 84 drives the two support structures 4 to move, thereby adjusting the position of the two support structures 4 according to the length of the material.

[0039] Example 3

[0040] like Figure 2 and Figure 3 As shown, based on Embodiment 2, this utility model provides a technical solution: Preferably, the base 3 is T-shaped, and the support structure 4 includes a horizontal plate 41. A connecting block 43 is symmetrically fixedly connected to the lower end of the horizontal plate 41. The inner cavity of the connecting block 43 on the same side is slidably connected to the outer surface of the base 3. A connecting plate 42 is fixedly connected to the opposite surfaces of the two connecting blocks 43. A connecting block 44 is symmetrically fixedly connected to the upper end of the horizontal plate 41. A top plate 45 is fixedly connected to the upper ends of the two connecting blocks 44. The upper end of the top plate 45 on the same side is fixedly connected to the lower end of the electric push rod 7, and the output end of the electric push rod 7 extends through the upper end of the top plate 45 to the lower part.

[0041] In this embodiment, the two connecting plates 42 are moved by the bidirectional lead screw 84, which in turn moves the horizontal plate 41 and the connecting block 43. The connecting block 43 slides on the outer surface of the base 3, and the base 3 supports and limits the connecting block 43. Then, when the horizontal plate 41 moves, it can move the connecting block 44 and the top plate 45. The connecting block 44 and the top plate 45 then move the drive structure 5, the clamping structure 6, and the electric push rod 7 together.

[0042] Example 4

[0043] like Figure 4 and Figure 5As shown, based on embodiment 3, this utility model provides a technical solution: preferably, the clamping structure 6 includes a second connecting plate 61 and a third connecting plate 63. The outer surfaces of the second connecting plate 61 and the third connecting plate 63 on the same side slide in the inner cavity of the second connecting block 44. The second connecting plate 61 and the third connecting plate 63 are fixedly connected to each other on one side. The upper end of the third connecting plate 63 is symmetrically provided with a sliding groove 64 that extends from the upper end of the third connecting plate 63 to the lower part. The output end of the electric push rod 7 on the same side is fixedly connected to the upper end of the second connecting plate 61. The two rubber blocks 62 on the same side are provided with several anti-slip textures on their opposite surfaces.

[0044] The drive structure 5 includes a housing 51. The side of the housing 51 closest to the second connecting block 44 is fixedly connected to the second connecting block 44. A gear 52 is rotatably connected to the inner cavity of the housing 51. A rack 54 is meshed with the outer surface of the gear 52 closest to the second connecting block 44. The upper end of the rack 54 is fixedly connected to the lower end of the second connecting plate 61. A rack 53 is meshed with the outer surface of the gear 52 furthest from the second connecting block 44. The lower end of the rack 53 is fixedly connected to the upper end of the third connecting plate 63.

[0045] In this embodiment, the output end of the electric push rod 7 drives the second connecting plate 61 to slide in the inner cavity of the second connecting block 44, thereby enabling the first rack 53 to run through the second connecting plate 61. Then, the first rack 53 meshes with the adjacent gear 52, causing the gear 52 to rotate. Then, the gear 52 drives the adjacent second rack 54 to mesh, causing the second rack 54 to move. Thus, the second rack 54 drives the third connecting plate 63 to move. Then, through the cooperation of the second connecting plate 61 and the third connecting plate 63, the two rubber blocks 62 can clamp and support the material.

[0046] The working principle of this double-sided clamping machine will be explained in detail below.

[0047] like Figure 1-6 As shown, when the device needs to be adjusted according to the length of the material, the motor 85 is first started to run, and the output end of the motor 85 drives the pulley 82 located on the lower side to rotate. Then, the pulley 82 and belt 83 work together to drive the pulley 82 located on the upper side to rotate. Next, the pulley 82 drives the double-acting screw 84 to rotate. Then, the double-acting screw 84 drives the two support structures 4 to move, so that the position of the two support structures 4 can be adjusted according to the length of the material.

[0048] The two connecting plates 42 are moved by the two-way lead screw 84, which in turn drives the horizontal plate 41 and the connecting block 43 to move. The connecting block 43 slides on the outer surface of the base 3, and the base 3 supports and limits the connecting block 43. Then, when the horizontal plate 41 moves, it can drive the connecting block 44 and the top plate 45 to move. Then, the connecting block 44 and the top plate 45 drive the drive structure 5, the clamping structure 6 and the electric push rod 7 to move together.

[0049] When the device needs to be adjusted according to the thickness of the material, the output end of the electric push rod 7 first drives the connecting plate 2 61 to slide in the inner cavity of the connecting block 2 44, so that the connecting plate 2 61 can drive the rack 1 53 to run. Then, the rack 1 53 meshes with the adjacent gear 52, driving the gear 52 to rotate. Then, the gear 52 drives the adjacent rack 2 54 to mesh, driving the rack 2 54 to move. So, the rack 2 54 can drive the connecting plate 3 63 to move. Then, with the cooperation of the connecting plate 2 61 and the connecting plate 3 63, the two rubber blocks 1 62 can clamp and support the material.

[0050] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
