Description

Technical Field

[0001] This invention relates to the field of auxiliary production equipment for alloy steel, and in particular to a clamping device for the production and processing of high-strength alloy steel. Background Technology

[0002] Alloy steel is steel in which alloying elements other than iron and carbon are added. It is an iron-carbon alloy formed by adding appropriate amounts of one or more alloying elements to ordinary carbon steel. Depending on the added elements and appropriate processing techniques, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low-temperature resistance, high-temperature resistance, and non-magnetic properties can be obtained. Alloy steel is widely used in various industries.

[0003] Existing clamping devices can only clamp specific types of alloy steel. When producing alloy steel of different sizes, the clamping device needs to be changed, which increases production costs. At the same time, in the production and processing of alloy steel pipes, it is often necessary to move the position of the steel pipe. Generally, the alloy steel pipe is clamped and transferred by a clamping device. The jaws of existing clamping devices are mostly in a vertical position, and the steel pipe is held in a horizontal state. This means that the steel pipe can only be transferred horizontally. In some cases, it is necessary to change the angle and direction of the steel pipe. To address this, we propose a clamping device for the production and processing of high-strength alloy steel.

The rear end of the rotating shaft passes through the outer wall of the rotating arm and extends into it to be fixedly connected to a gear. The bottom end of the gear is meshed with a turntable. The bottom end of the turntable is fixedly connected to the connecting cylinder via a connecting plate.

[0010] As a preferred embodiment of the clamping device for high-strength alloy steel production and processing described in this invention, the slide groove is provided with two parts, namely a first part and a second part. The first part is an upwardly sloping arc groove, and the second part is a horizontal arc groove. The slider is slidably connected in the second part.

[0011] As a preferred embodiment of the clamping device for high-strength alloy steel production and processing described in this invention, the bottom end of the connecting cylinder is provided with a first slot and a second slot, with the first slot located at the center and the second slot located outside the first slot.

[0012] In a preferred embodiment of the clamping device for high-strength alloy steel production and processing described in this invention, the insertion assembly includes a plug and a rod adapted to the first slot and the second slot, the plug being inserted into the first slot, and the top end of the plug abutting against the telescopic sleeve.

[0013] In a preferred embodiment of the clamping device for high-strength alloy steel production and processing described in this invention, the connecting cylinder has a rotating groove inside, and one end of the rotating groove is connected to the second slot.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0032] Reference Figures 1-8 This embodiment provides a clamping device for the production and processing of high-strength alloy steel, including an installation module 100, a drive module 200, a connection module 300, and a gripping module 400. The installation module 100 provides the necessary conditions for the installation of the drive module 200, the connection module 300, and the gripping module 400. The drive module 200 provides the necessary conditions for the rotation, lifting, and movement of the electric gripper 401. The connection module 300 facilitates the installation and disassembly of the electric gripper 401.

[0033] Specifically, the mounting module 100 includes a base 101, a mounting column 102 fixedly connected to the top of the base 101, a mounting plate 103 provided at the top of the mounting column 102, and a rotating arm 104 provided at the top of the mounting plate 103. The electric cylinder 201 in the drive module 200 is located inside the mounting column 102, the servo motor 202 is located inside the mounting plate 103, and the rotating motor 203 is located outside the rotating arm 104.

[0034] like Figure 1 and 2 As shown, the output end of the electric cylinder 201 is movably connected to a telescopic rod 204. The top end of the telescopic rod 204 penetrates the inner top wall of the mounting column 102 and extends to the outside, where it is fixedly connected to the bottom end of the mounting plate 103. The output end of the servo motor 202 is connected to a drive shaft 205 via a coupling. The top end of the drive shaft 205 penetrates the inner top wall of the mounting plate 103 and extends to the outside, where it is fixedly connected to the bottom end of the rotating arm 104.

[0035] In this device, the electric cylinder 201, servo motor 202, and rotary motor 203 are all existing technologies, and their specific structures will not be described in detail. When the electric cylinder 201 is started, the telescopic rod 204 inside the electric cylinder 201 can perform piston movement. The telescopic rod 204 can drive the mounting plate 103, the rotating arm 104, and the electric gripper 401 to move up and down. When the servo motor 202 is started, it can drive the drive shaft 205 to rotate. The drive shaft 205 can drive the rotating arm 104 and the electric gripper 401 to rotate. This structure allows the electric gripper to perform alloy steel gripping work in a wider range, improving the practicality of the device.

[0036] Furthermore, the output end of the rotating motor 203 is connected to the rotating shaft 206 via a coupling. The rear end of the rotating shaft 206 passes through the outer wall of the rotating arm 104 and extends into it, where a gear 207 is fixedly connected. The bottom end of the gear 207 is meshed with a turntable 208. The bottom end of the turntable 208 is fixedly connected to the connecting cylinder 301 via a connecting plate. When the rotating motor 203 starts, it can drive the rotating shaft 206 and the gear 207 to rotate. Then, through the turntable 208, which has transmission teeth at the connection between the turntable 208 and the gear 207, it can drive the turntable 208 to rotate at a certain angle. The turntable 208, through the connecting plate at its bottom end, can drive the connecting module 300 and the electric gripper 401 below to rotate at a certain angle, thereby improving the applicability of the electric gripper 401 and enabling it to grip alloy steel more accurately.

[0037] Furthermore, the connecting module 300 includes a connecting cylinder 301 located at the bottom right side of the rotating arm 104. A rotating sleeve 302 is rotatably connected inside the connecting cylinder 301. A sliding groove 303 is provided on the outer side of the rotating sleeve 302. A telescopic component 304 is provided at the top of the rotating sleeve 302. A snap-fit ​​component 305 is provided on the outer side of the rotating sleeve 302. The rotating sleeve 302 can rotate within the connecting cylinder 301. The telescopic component 304 can both drive the rotating sleeve 302 to rotate and return the rotating sleeve 302 to its original position before rotation.

[0038] Specifically, the telescopic component 304 includes a telescopic sleeve 304a disposed inside the rotating sleeve 302, sliders 304b disposed on both sides of the telescopic sleeve 304a, a telescopic spring 304c fixedly connected to the top of the telescopic sleeve 304a, and the top of the telescopic spring 304c fixedly connected to the inner top wall of the connecting cylinder 301. The slide groove 303 is provided with two parts, namely a first part s and a second part n. The first part s is an upwardly sloping arc groove, and the second part n is a horizontal arc groove. The sliders 304b are slidably connected in the second part n.

[0039] More specifically, the gripping module 400 includes an electric gripper 401 positioned directly below the connecting cylinder 301. A plug-in assembly 402 is fixedly mounted on the top of the electric gripper 401. The bottom of the connecting cylinder 301 has a first slot 301a and a second slot 301b, with the first slot 301a located at the center and the second slot 301b located outside the first slot 301a. The plug-in assembly 402 includes a plug cylinder 402a and a plug rod 402b adapted to the first and second slots 301a and 301b, respectively. The plug cylinder 402a is inserted into the first slot 301a, and its top abuts against the telescopic sleeve 304a. A rotating groove 301c is formed inside the connecting cylinder 301, and one end of the rotating groove 301c is connected to… The second slot 301b is connected to the locking assembly 305, which includes a locking block 305a fixedly installed on the outside of the rotating sleeve 302. A return spring 305b is provided on one side of the locking block 305a. Both the locking block 305a and the return spring 305b are located in the rotating groove 301c. One side of the return spring 305b is fixedly connected to the inner wall of the connecting cylinder 301. A lever 305c is fixedly connected to the outside of the locking block 305a. One end of the lever 305c penetrates the inner wall of the connecting cylinder 301 and extends to its outside. The top of the insertion rod 402b is provided with a locking groove 402b1 that matches the locking block 305a. The insertion rod 402b is inserted into the second slot 301b, and the locking end of the locking block 305a is locked in the locking groove 402b1.

[0040] Combination Figures 4-8 As shown, at this time, the gripping module 400 and the connecting module 300 are in a connected state (i.e., the electric gripper 401 is installed on the whole device). When the electric gripper 401 needs to be replaced, the operator only needs to move the lever 305c. The lever 305c can drive the locking block 305a to release the locking and fixing of the insertion rod 402b. At the same time, the locking block 305a can drive the rotating sleeve 302 to achieve a certain rotation. At this time, the slider 304b can move to the connection between the first part s and the second part n. And because the telescopic spring 304c is at this time... In the compressed state, and without the locking block 305a limiting and fixing the insertion rod 402b, the telescopic spring 304c can push the insertion cylinder 402a out of the connecting cylinder 301 through the telescopic sleeve 304a, thereby separating the electric gripper 401 from the connecting module 300 and completing the disassembly of the electric gripper 401. This structure is reasonably designed, simple to operate, and convenient to use, saving workers a lot of replacement time and improving work efficiency. At the same time, it solves the problem that traditional gripping devices cannot meet gripping needs and saves production costs.

[0041] When a new electric gripper 401 needs to be installed, the operator aligns the insert 402a and the insert rod 402b with the first slot 301a and the second slot 301b, and then pushes them upwards. After the insert 402a abuts against the telescopic sleeve 304a inside the connecting cylinder 301, it can push the telescopic sleeve 304a to move upwards. The telescopic sleeve 304a can drive the slider 304b to move upwards. Since the first part s of the slide groove 303 is an upwardly sloping arc groove, when the slider 304b moves vertically upwards, it can drive the rotating sleeve 302 to deflect. As a result, the locking end of the locking block 305a on the outside of the rotating sleeve 302 can move away from the second slot 301b, thereby releasing the blockage of the second slot 301b and ensuring that the insert rod 402b can smoothly enter and be inserted into the second slot. Inside slot 301b, the rotation of the locking block 305a compresses the return spring 305b. When the telescopic sleeve 304a moves the slider 304b to the junction of the first part s and the second part n, the insertion rod 402b can be fully inserted into the second slot 301b. At this time, without the obstruction of the side wall of the first part s, and under the rebound force of the return spring 305b, the locking block 305a can spring back to its initial position. Thus, the locking block 305a can pass into the second slot 301b and be inserted into the slot 402b1 of the insertion rod 402b, thereby limiting and fixing the insertion rod 402b and preventing it from falling off. This completes the installation of the electric gripper 401. The entire installation process is simple and convenient, further improving the overall work efficiency.
