Description

Technical Field

[0001] This utility model relates to the technical field of material clamping devices, specifically a material clamping device with a large length-to-diameter ratio that can be flexibly adjusted. Background Technology

[0002] Large length-to-diameter ratio material clamping devices are devices specifically designed for clamping and handling materials with large length-to-diameter ratios, such as long shaft parts. These devices are designed and used to ensure the stability and rigidity of the workpiece during processing, thereby guaranteeing processing quality and efficiency. However, existing material clamping devices still encounter some problems in actual use.

[0003] For example, patent application number CN202323425050.8 relates to a clamping device for turning the outer diameter of parts with a large length-to-diameter ratio. It includes: a machine tool chuck, a center, and a reverse center; the center is a cone with a coaxial threaded hole inside; the reverse center is a stepped shaft with a tapered hole inside, the tapered hole having a clearance fit with the outer shape of the cone; one end of the part with a large length-to-diameter ratio is fixed by the machine tool chuck, and the other end is screwed into the center, providing a quick clamping function. Existing material clamping devices often use a single clamping mechanism to fix materials with a large length-to-diameter ratio, which is inconvenient when transferring materials of different specifications according to actual needs.

[0004] To address the aforementioned problems, a flexible, adjustable material clamping device with a large length-to-diameter ratio is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a flexible adjustable material clamping device for materials with a large length-to-diameter ratio. By using this device, the problem of inconvenience in operation is solved when existing material clamping devices often use a single clamping mechanism to fix materials with a large length-to-diameter ratio, and when it is necessary to transfer materials of different specifications according to actual conditions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexible adjustable material clamping device with a large length-to-diameter ratio, comprising a clamping device body and a sliding platform slidably connected to the top of the clamping device body. The clamping device body is provided with a conveying mechanism, which serves to convey materials with a large length-to-diameter ratio. The conveying mechanism includes a sliding platform fixedly connected to one end of the clamping device body. A fixed frame is fixedly connected to the top of the sliding platform. A telescopic cylinder is fixedly connected inside the fixed frame. The output end of the telescopic cylinder is fixedly connected to the sliding frame.

[0007] Preferably, the output end of the motor is fixedly connected to a transmission screw, the transmission screw is threadedly connected to a sliding block, and the sliding block is fixedly connected to a sliding table.

[0008] The above-mentioned structure is designed so that the transmission screw is driven by a motor to rotate, and the sliding block drives the sliding table to move along the body of the clamping device by using the thread transmission principle. This allows the horizontal position of the conveying mechanism to be adjusted to adapt to different material conveying paths and working scenarios.

[0009] Preferably, a second motor is fixedly connected to one side of the sliding frame, and a telescopic rod is rotatably connected between the fixed frame and the sliding frame. Both ends of the telescopic rod are fixedly connected to a first bevel gear.

[0010] With the above-mentioned structural design, the second motor drives the telescopic rod to rotate, which in turn causes the first bevel gears at both ends to rotate synchronously. This lays the foundation for the subsequent transmission of power to the first screw rod with positive and negative threads through the meshing of the bevel gears, realizing the transmission and conversion of power and providing a power source for adjusting the spacing between the connecting platforms.

[0011] Preferably, a set of bevel gear one is fixedly connected to the output end of motor two, bevel gear two is meshed on one side of bevel gear one, and a positive and negative thread screw one is fixedly connected to one side of bevel gear two.

[0012] The above-mentioned structure is designed so that the rotation direction of the telescopic rod is changed and transmitted to the positive and negative thread screws through the meshing transmission of bevel gear one and bevel gear two. By utilizing the thread characteristics of the positive and negative thread screws, the connecting platforms at the left and right ends can slide towards or away from each other on the top of the fixed frame, thereby realizing the adjustment of the distance between the connecting platforms to adapt to materials with large length-to-diameter ratios of different lengths.

[0013] Preferably, both ends of the positive and negative threaded screw are threadedly connected to a connecting platform, and the connecting platform is slidably connected to the top of the fixing frame.

[0014] With the above-mentioned structural design, when the positive and negative thread screws rotate, the threads at the left and right ends rotate in opposite directions, causing the connecting platform to slide on the top of the fixed frame. This enables precise adjustment of the distance between the connecting platforms, thereby allowing the clamping frame to adapt to the clamping requirements of materials of different specifications, and improving the flexibility and versatility of the device.

[0015] Preferably, a clamping frame is fixedly connected to the top of the connecting platform, a motor three is fixedly connected inside the clamping frame, and a positive and negative thread screw two is fixedly connected to the output end of the motor three.

[0016] With the above-mentioned structural design, the connecting platform supports the clamping frame, and the three motors drive the two positive and negative thread screws to rotate. Through the thread transmission, the contact platform moves up and down inside the clamping frame, thereby driving the clamping block to clamp the material. This structural design provides power and transmission for material clamping, ensuring the smooth operation of the clamping operation.

[0017] Preferably, both ends of the positive and negative threaded screw are threadedly connected to contact platforms, the contact platforms are slidably connected inside the clamping frame, and a clamping block is fixedly connected to one side of the contact platform.

[0018] With the above-mentioned structural design, when the two screws rotate, the contact platforms at the upper and lower ends move synchronously under the action of the threads, driving the clamping block to clamp the material. The spring between the clamping block and the contact platform plays a buffering role, ensuring firm clamping while effectively preventing damage to the material due to excessive clamping force, thus improving the practicality and reliability of the device.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This application achieves flexible adjustment of the overall structure by setting up a motor, telescopic cylinder, sliding table and connecting table, which facilitates the transportation operation of materials with large length-to-diameter ratio by the staff. It solves the problem that the existing material clamping device often fixes materials with large length-to-diameter ratio by a single clamping mechanism, which is inconvenient when it is necessary to transfer materials of different specifications according to the actual situation.

[0021] 2. This application, through the setting of motor three, positive and negative threaded screw two, contact table and clamping block, can effectively prevent damage to materials with large length-to-diameter ratio, improve the use effect, and solve the problem that existing material clamping devices generally use cylinders to clamp materials with large length-to-diameter ratio, which is not convenient to control the clamping force of the cylinder and is prone to damage to materials with large length-to-diameter ratio.

[0030] Combination Figures 1-3 A flexible adjustable material clamping device with a large length-to-diameter ratio includes a clamping device body 1 and a sliding table 11 slidably connected to the top of the clamping device body 1. The clamping device body 1 is provided with a conveying mechanism, which is used to convey materials with a large length-to-diameter ratio. The conveying mechanism includes a sliding table 11 fixedly connected to one end of the clamping device body 1. A fixed frame 12 is fixedly connected to the top of the sliding table 11. A telescopic cylinder 121 is fixedly connected inside the fixed frame 12. A sliding frame 122 is fixedly connected to the output end of the telescopic cylinder 121.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the problem that existing material clamping devices often rely on a single clamping mechanism to hold materials with large length-to-diameter ratios, leading to operational inconvenience when transferring materials of different specifications as needed, this embodiment discloses the following technical solution, specifically as follows: Figures 1-4As shown, the output end of motor 111 is fixedly connected to a transmission screw 112, and the transmission screw 112 is threadedly connected to a sliding block 113. The sliding block 113 is fixedly connected to the sliding table 11. Motor 2 13 is fixedly connected to one side of the sliding frame 122. A telescopic rod 131 is rotatably connected between the fixed frame 12 and the sliding frame 122. Both ends of the telescopic rod 131 are fixedly connected to bevel gears 132. A set of bevel gears 132 is fixedly connected to the output end of motor 2 13. One side of bevel gears 132 is meshed with bevel gear 2 133. One side of bevel gear 2 133 is fixedly connected to a screw 134 with reverse threads. Both ends of the screw 134 with reverse threads are threaded to a connecting platform 135. The connecting platform 135 is slidably connected to the top of the fixed frame 12. A clamping frame 14 is fixedly connected to the top of the connecting platform 135. When it is necessary to clamp materials during use, motor 2 13 located inside the sliding frame 122 can be started first. 3 drives the telescopic rod 131 to rotate, which in turn causes the two sets of bevel gears 132 to rotate. The bevel gears 132 drive the bevel gears 133 to rotate, which in turn causes the positive and negative thread screws 134 to rotate. The positive and negative thread screws 134 can adjust the distance between the connecting platforms 135, thus adapting to materials of different lengths. After the clamping frame 14 has clamped the material, the motor 111 located on one side of the clamping device body 1 can be started. The motor 111 drives the transmission screw 112 to rotate, which in turn causes the sliding block 113 to move. The sliding block 113 drives the sliding table 11 to move, thus transferring the material to the designated position. The operator can also start the telescopic cylinder 121 located inside the sliding table 11. The telescopic cylinder 121 drives the sliding frame 122 to move, thus changing the transmission direction of the sliding frame 122, thus adapting to different working environments and realizing the ability to flexibly adjust the overall structure, which facilitates the operation of transporting materials with large length-to-diameter ratios.

[0034] Example 2:

[0035] To address the problem that existing material clamping devices generally rely on cylinders to hold materials with large length-to-diameter ratios, which makes it difficult to control the clamping force and can easily damage such materials, this embodiment discloses the following technical solution, specifically as follows: Figure 4 and Figure 5As shown, a motor 141 is fixedly connected inside the clamping frame 14. A threaded screw 142 is fixedly connected to the output end of the motor 141. Both ends of the threaded screw 142 are threadedly connected to contact platforms 143. The contact platforms 143 are slidably connected inside the clamping frame 14. A clamping block 144 is fixedly connected to one side of the contact platform 143. When it is necessary to clamp materials with a large length-to-diameter ratio through the clamping frame 14, the motor 141 inside the clamping frame 14 can be activated. The motor 141 drives the threaded screw 142 to rotate, thereby causing the contact platform 143 to move. The contact platform 143 drives the clamping block 144 to move, thereby achieving the clamping effect on materials with a large length-to-diameter ratio. The spring between the clamping block 144 and the contact platform 143 provides a certain buffering effect, which can effectively prevent damage to materials with a large length-to-diameter ratio and improve the usage effect.
