[0002] Electric linear actuators, also known as linear drives, can be considered as an extension of the structure of rotating motors. Electric linear actuators are a new type of linear actuator mainly composed of motor linear actuators and control devices. Electric linear actuators are electric drive devices that convert the rotary motion of the motor into the linear reciprocating motion of the linear actuator. They can be used as actuators in various simple or complex process flows to achieve remote control, centralized control or automatic control. Electric linear actuators are general-purpose auxiliary drive devices that can be widely used in electricity, machinery, metallurgy, transportation, mining, petroleum, chemical industry, lifting, transportation, construction, grain and feed processing and other industries. They have the characteristics of reliable performance, sensitive action, smooth operation, equal push and pull force, and good environmental adaptability.

[0003] During the production and processing of electric push rods, a positioning device is required to fix them. However, the positioning device for electric push rod processing in the existing technical solution has a relatively simple structure and can only fix a single type of electric push rod, which leads to limitations in the use of the positioning device. Utility Model Content

[0004] The embodiment of the present application provides a positioning device for processing an electric push rod, thereby solving the technical problem that the positioning device for processing an electric push rod in the prior art solution can only fix a single type of electric push rod due to its relatively simple structure, which results in the positioning device being subject to limitations when in use.

[0005] The technical solution adopted in the embodiment of the present application is as follows:

[0006] A positioning device for electric push rod processing, comprising a base, a bending support frame for supporting the electric push rod, a positioning mechanism for fixing the electric push rod, and a sliding device for driving the bending support frame to move; the base is provided with a slide groove; the sliding device is arranged in the slide groove; two groups of the bending support frames symmetrically arranged are arranged on the sliding end of the sliding device; two groups of the positioning mechanisms symmetrically arranged are arranged on the two groups of the bending support frames;

[0007] The positioning mechanism includes a push plate, a baffle plate for abutting against the electric push rod, a buffer assembly for buffering the baffle plate, and a first threaded rod threadedly connected to the bending support frame; the push plate is arranged at one end of the first threaded rod; the buffer assembly is arranged between the push plate and the baffle plate.

[0008] A further technical solution is: the buffer assembly includes a spring for buffering the baffle and a telescopic rod for limiting the spring; the spring is arranged around the telescopic rod; the telescopic end of the telescopic rod is connected to the baffle; and the other end of the telescopic rod is connected to the push plate.

[0009] A further technical solution is: the sliding device includes a slider, a second threaded rod for driving the slider to slide, and a bearing seat for supporting the second threaded rod; two groups of symmetrically placed sliders are threadedly connected to the second threaded rod; the two groups of sliders are both provided with the bending support frame; the two groups of sliders slide in the slide groove; the bearing seats are provided at both ends of the second threaded rod; the two groups of bearing seats are both arranged in the slide groove.

[0010] A further technical solution is: the positioning mechanism also includes a rubber pad; the rubber pad is arranged on the baffle.

[0011] A further technical solution is: the positioning mechanism also includes a first threaded handle; the first threaded handle is arranged at the other end of the first threaded rod.

[0012] A further technical solution is: the sliding device also includes a second threaded handle; the second threaded handle is arranged at one end of the second threaded rod.

[0013] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0014] 1. Due to the use of the base, bending support frame, positioning mechanism, sliding device and slide groove, when the electric push rod needs to be processed and positioned, the staff first works through the sliding end of the sliding device to make the two sets of bending support frames slide close to each other or slide away from each other along the top of the base. When the two sets of bending support frames slide close to each other or away from each other to a certain distance, the electric push rod to be processed is placed on the top of the two sets of bending support frames, and then the first threaded rod in each set of positioning mechanism is rotated in turn, so that each set of first threaded rod drives the corresponding baffle to abut against the electric push rod, and the electric push rod can be firmly fixed on the two sets of bending support frames. When each set of baffles abuts against both sides of the electric push rod, the buffer assembly set between the baffle and the push plate will play a certain buffering role on the electric push rod, thereby preventing the baffle from causing unnecessary wear on the electric push rod, and thus playing a certain protective role on the electric push rod. Since the distance between the two groups of bending support frames can be adjusted according to the sliding of the sliding end of the sliding device, and the distance between each two groups of baffles can be automatically adjusted according to the rotation of the corresponding first threaded rod, the processing positioning device can fix electric push rods of different models, thereby greatly improving the practicability of the processing positioning device.

[0015] 2. Due to the use of springs and telescopic rods, when the baffle is against the electric push rod, the electric push rod will exert a certain extrusion force on the baffle, causing the baffle to compress the spring and telescopic rod. At this time, the spring in a compressed state will exert a certain reaction force on the baffle, thereby enabling the baffle to be firmly against the electric push rod. When the spring is in a compressed state, the telescopic rod can prevent the spring from deforming, thereby providing a certain protection for the spring. At the same time, the spring in a compressed state can provide a certain buffering effect on the electric push rod.

[0016] 3. Due to the arrangement of the slider, the second threaded rod and the bearing seat, by rotating the second threaded rod, since the second threaded rod is threaded with two sets of symmetrically placed sliders, and both sets of sliders are slidably connected in the slide groove, when the second threaded rod rotates, the two sets of sliders can slide close to each other or slide away from each other in the slide groove at the same time. Since the two sets of sliders are fixedly connected with the bending support frame, the two sets of bending support frames can slide close to each other or slide away from each other at the same time.

[0017] 4. Due to the setting of the rubber pad, when the baffle is against the electric push rod, the rubber pad on the baffle will contact the electric push rod, thereby providing a certain degree of protection for the electric push rod.

[0018] 5. Due to the setting of the first threaded handle, the first threaded rod can be driven to rotate together by rotating the first threaded handle, thereby making it more convenient for the staff to operate.

[0019] 6. Due to the setting of the second threaded handle, the second threaded rod can be driven to rotate together by rotating the second threaded handle, thereby making it more convenient for the staff to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The embodiment of the present application provides a positioning device for processing an electric push rod, thereby solving the technical problem that the positioning device for processing an electric push rod in the prior art solution can only fix a single type of electric push rod due to its relatively simple structure, which results in the positioning device being subject to limitations when in use.

[0026] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] A positioning device for electric push rod processing, such as Figure 1 and Figure 2 As shown, it includes a base 1, a bending support frame 2 for supporting an electric push rod, a positioning mechanism 3 for fixing the electric push rod, and a sliding device 4 for driving the bending support frame 2 to move. The base 1 is provided with a slide groove 11. The sliding device 4 is arranged in the slide groove 11. Two groups of symmetrically placed bending support frames 2 are arranged on the sliding end of the sliding device 4. Two groups of symmetrically placed positioning mechanisms 3 are arranged on the two groups of bending support frames 2.

[0029] The positioning mechanism 3 includes a push plate 31, a baffle plate 32 for abutting against the electric push rod, a buffer assembly 33 for buffering the baffle plate 32, and a first threaded rod 34 threadedly connected to the bending support frame 2. The push plate 31 is arranged at one end of the first threaded rod 34. The buffer assembly 33 is arranged between the push plate 31 and the baffle plate 32.

[0030] A slide groove 11 is provided on the top of the base 1. The sliding device 4 is fixedly connected in the slide groove 11. Two groups of symmetrically placed bending support frames 2 are fixedly connected to the sliding end of the sliding device 4. Through the operation of the sliding end of the sliding device 4, the two groups of bending support frames 2 can slide close to each other or slide away from each other along the top of the base 1 at the same time. Two groups of symmetrically placed positioning mechanisms 3 are fixed on both groups of bending support frames 2. The push plate 31 is fixedly connected to one end of the first threaded rod 34. One end of the buffer assembly 33 is fixedly connected to the push plate 31, and the other end of the buffer assembly 33 is fixedly connected to the baffle 32.

[0031] Due to the use of the base 1, the bending support frame 2, the positioning mechanism 3, the sliding device 4 and the slide groove 11, when the electric push rod needs to be processed and positioned, the staff first works through the sliding end of the sliding device 4, so that the two groups of bending support frames 2 slide close to each other or slide away from each other along the top of the base 1. When the two groups of bending support frames 2 slide close to each other or slide away from each other to a certain distance, the electric push rod to be processed is placed on the top of the two groups of bending support frames 2, and then the first threaded rod 34 in each group of positioning mechanisms 3 is rotated in turn, so that each group of first threaded rods 34 drives the corresponding baffle 32 to abut against the electric push rod, and the electric push rod can be firmly fixed on the two groups of bending support frames 2. When each group of baffles 32 abuts against both sides of the electric push rod, the buffer assembly 33 set between the baffle 32 and the push plate 31 will play a certain buffering role on the electric push rod, thereby preventing the baffle 32 from causing unnecessary wear to the electric push rod, so as to play a certain protective role on the electric push rod. Since the distance between the two groups of bending support frames 2 can be adjusted according to the sliding end of the sliding device 4, and the distance between each two groups of baffles 32 can be automatically adjusted according to the rotation of the corresponding first threaded rod 34, the processing positioning device can fix electric push rods of different models, thereby greatly improving the practicability of the processing positioning device.

[0032] like Figure 3 As shown, the buffer assembly 33 includes a spring 331 for buffering the baffle 32 and a telescopic rod 332 for limiting the spring 331. The spring 331 is arranged around the telescopic rod 332. The telescopic end of the telescopic rod 332 is connected to the baffle 32. The other end of the telescopic rod 332 is connected to the push plate 31.

[0033] The telescopic end of the telescopic rod 332 is fixedly connected to the baffle 32. The other end of the telescopic rod 332 is fixedly connected to the push plate 31. One end of the spring 331 is fixedly connected to the baffle 32. The other end of the spring 331 is fixedly connected to the push plate 31.

[0034] Due to the arrangement of the spring 331 and the telescopic rod 332, when the baffle 32 abuts against the electric push rod, the electric push rod will exert a certain extrusion force on the baffle 32, so that the baffle 32 compresses the spring 331 and the telescopic rod 332. At this time, the spring 331 in a compressed state will exert a certain reaction force on the baffle 32, thereby enabling the baffle 32 to abut firmly against the electric push rod. When the spring 331 is in a compressed state, the telescopic rod 332 can prevent the spring 331 from deforming, thereby providing a certain protection for the spring 331. At the same time, the spring 331 in a compressed state can provide a certain buffering effect on the electric push rod.

[0035] like Figure 4As shown, the sliding device 4 includes a slider 41, a second threaded rod 42 for driving the slider 41 to slide, and a bearing seat 43 for supporting the second threaded rod 42. Two groups of sliders 41 are threadedly connected to the second threaded rod 42 and are symmetrically placed. The two groups of sliders 41 are both provided with a bending support frame 2. The two groups of sliders 41 slide in the slide groove 11. The two ends of the second threaded rod 42 are provided with a bearing seat 43. The two groups of bearing seats 43 are both arranged in the slide groove 11.

[0036] The tops of the two sets of sliders 41 are fixedly connected to the bending support frame 2. The two ends of the second threaded rod 42 are provided with bearing seats 43, and the two ends of the second threaded rod 42 are respectively fixedly connected to the inner rings of the bearings in the two sets of bearing seats 43. The two sets of bearing seats 43 are fixedly connected in the slide groove 11.

[0037] Due to the arrangement of the slider 41, the second threaded rod 42 and the bearing seat 43, by rotating the second threaded rod 42, since two groups of sliders 41 symmetrically placed are threadedly connected to the second threaded rod 42, and both groups of sliders 41 are slidably connected to the slide groove 11, when the second threaded rod 42 rotates, the two groups of sliders 41 can slide close to each other or slide away from each other in the slide groove 11 at the same time. Since the two groups of sliders 41 are fixedly connected to the bending support frame 2, the two groups of bending support frames 2 can slide close to each other or slide away from each other at the same time.

[0038] like Figure 2 As shown, the positioning mechanism 3 further includes a rubber pad 35. The rubber pad 35 is arranged on the baffle 32.

[0039] The rubber pad 35 is fixedly connected to the baffle 32 .

[0040] Due to the provision of the rubber pad 35 , when the baffle 32 abuts against the electric push rod, the rubber pad 35 on the baffle 32 will contact the electric push rod, thereby being able to provide a certain degree of protection for the electric push rod.

[0041] like Figure 2 As shown, the positioning mechanism 3 further includes a first threaded handle 36. The first threaded handle 36 is arranged at the other end of the first threaded rod 34.

[0042] The first threaded handle 36 is fixedly connected to the other end of the first threaded rod 34 .

[0043] Due to the provision of the first threaded handle 36 , the first threaded rod 34 can be driven to rotate together by rotating the first threaded handle 36 , thereby making it more convenient for the staff to operate.

[0044] like Figure 4 As shown, the sliding device 4 further includes a second threaded handle 44. The second threaded handle 44 is arranged at one end of the second threaded rod 42.

[0045] The second threaded handle 44 is fixedly connected to one end of the second threaded rod 42 .

[0046] Due to the provision of the second threaded handle 44, the second threaded rod 42 can be driven to rotate together by rotating the second threaded handle 44, thereby making it more convenient for the staff to operate.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.
