Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a metal rod thermal spraying clamp. Background Technology

[0002] Metal rods are widely used in daily life, so thermal spraying is necessary on their surfaces during actual processing.

[0003] Chinese utility model patent CN210994904U discloses a precision alloy bar surface treatment device, including: a power supply box, a drive motor, a gearbox, a main shaft, a clamping plate, a bar clamp, a spraying tank, a spraying material tank, and a spraying device. When surface treatment of precision alloy bars is required, the bar clamp can be used to fix the bar, and the drive motor drives the main shaft to rotate through the gearbox. The main shaft is coaxially connected to the bar clamp through the clamping plate, thereby driving the bar to rotate around the axis. The spraying device can spray the material in the spraying material tank downwards onto the surface of the bar, and evenly spray it on the outer circumference of the bar as it rotates.

[0004] Although the aforementioned patent can spray coating on the surface of rods, it uses a clamping plate and rod clamp to hold and fix the rods, which is a relatively complex structure. Moreover, the rod clamp requires rotating each adjusting stud during the clamping process, which is cumbersome, time-consuming and labor-intensive. This makes it difficult to quickly and conveniently replace the rods after spraying, affecting the speed of rod replacement and reducing spraying efficiency. Utility Model Content

[0023] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figure 1-2As shown, an embodiment of this utility model provides a metal rod thermal spraying fixture, including: a base plate 1, which is horizontally arranged; and a clamping mechanism, which includes two support parts arranged facing each other on the upper part of the base plate 1, two rotating parts correspondingly arranged on the two support parts, two limiting parts correspondingly arranged on the two support parts, and a driving part arranged on one of the support parts; wherein, the two rotating parts are arranged linearly, and the rotation direction of the two rotating parts is perpendicular to their arrangement direction, each limiting part includes a plurality of rolling elements, the plurality of rolling elements are arranged vertically on the upper part of the corresponding support part in an arc-shaped trajectory, the plurality of rolling elements are evenly distributed on both sides of the rotating part and are elastically slidably connected to the upper part of the support part along the radial direction of their arc-shaped trajectory, and the power output end of the driving part is connected to one of the rotating parts;

[0025] The metal rod is placed on two rotating parts, and several rolling elements on each support part roll against the side wall of the metal rod. Then, the drive unit is activated to rotate one of the rotating parts, so that the metal rod rotates synchronously. Then, thermal spraying is performed on the surface of the metal rod. The operation is simple and convenient, and the metal rod can be quickly clamped and replaced, which improves the spraying efficiency. Moreover, since the several rolling elements are elastically slidably connected to the upper part of the support part along their arc-shaped trajectory, the several rolling elements can be used to clamp and limit metal rods of different specifications, which improves the applicability of the fixture.

[0026] like Figure 1-2 As shown, according to another embodiment of the present invention, the metal rod thermal spraying fixture further optimizes its supporting part, rolling elements, rotating part, and driving part. Each supporting part includes a supporting column 2 vertically fixedly installed on the base plate 1 and a clamping seat 3 fixedly connected to the end of the supporting column 2 away from the base plate 1. The clamping seat 3 is an arc structure bent towards the base plate 1. Each rotating part is disposed on the bottom inner wall of the corresponding clamping seat 3. A plurality of rolling elements are evenly distributed circumferentially along the inner wall of the corresponding clamping seat 3 and elastically slidably connected to it along the radial direction of the clamping seat 3. The driving part is disposed on the side of one clamping seat 3 away from the other clamping seat 3. The arc structure of the clamping seat 3 can better place the metal rod, and the plurality of rolling elements can also perfectly fit with the side wall of the metal rod, ensuring clamping stability.

[0027] Each of the aforementioned rolling elements includes a plurality of sliding rods 51 that slide radially through the clamping seat 3, a mounting seat 5 fixedly connected to one end of the plurality of sliding rods 51 located inside the clamping seat 3, and a limiting roller 6 rotatably connected to the mounting seat 5. A limiting plate 53 is fixedly installed on the end of each sliding rod 51 located outside the clamping seat 3 to prevent the sliding rod 51 from disengaging from the clamping seat 3. A spring 52 is sleeved on each sliding rod 51, and the spring 52 is elastically connected between the inner wall of the clamping seat 3 and the mounting seat 5. The limiting roller 6 is arranged along the axial direction of the clamping seat 3. During the rotation of the metal rod by the rotating part, the plurality of limiting rollers 6 on each clamping seat 3 can roll and abut against the side wall of the metal rod, so that while clamping and limiting the metal rod, the rotational stability and smoothness of the metal rod can also be guaranteed. Preferably, each mounting seat 5 is fixedly connected with two sliding rods 51, which reduces costs while ensuring the sliding stability of the mounting seat 5.

[0028] Each of the rotating parts includes two rotating components arranged in opposite directions parallel to the axial direction of the clamping seat 3, wherein one of the rotating components of one rotating part is connected to the power output end of the driving part; each of the rotating components includes two opposing brackets 31 fixedly mounted on the inner wall of the bottom of the clamping seat 3 perpendicular to the axial direction of the clamping seat 3, and a driving roller 4 rotatably mounted between the two brackets 31 via a rotating shaft 41. The driving roller 4 is arranged along the axial direction of the clamping seat 3, wherein one rotating shaft 41 freely passes through the bracket 31 and is connected to the power output end of the driving part; the rotating shaft 41 is driven to rotate by a motor 44 to drive the metal rod to rotate synchronously.

[0029] A fixing plate 32 is horizontally fixedly installed on the side wall of one of the clamping seats 3 away from the other clamping seat 3. The driving unit includes a motor 44 fixedly installed on the upper part of the fixing plate 32. The power output shaft of the motor 44 is coaxially and fixedly connected to the corresponding rotating shaft 41.

[0030] like Figure 1 As shown, according to another embodiment of the present invention, the metal rod thermal spraying fixture preferably includes a transmission component between two rotating shafts 41 arranged near the motor 44. The motor 44 drives the two rotating shafts 41 and two drive rollers 4 to rotate synchronously and in the same direction through the transmission component. The transmission component includes two pulleys 42 and a belt 43 connected between the two pulleys 42. The two rotating shafts 41 near the motor 44 freely pass through the bracket 31 and are coaxially fixedly connected to the two pulleys 42. One rotating shaft 41 passes through the pulley 42 and is coaxially fixedly connected to the power output shaft of the motor 44. The motor 44 drives one of the rotating shafts 41 to rotate. Through the transmission of the two pulleys 42 and the belt 43, the two rotating shafts 41 drive the two drive rollers 4 to rotate synchronously and in the same direction, thereby driving the metal rod to rotate for thermal spraying.

[0031] The working principle of this utility model is as follows: When using this utility model, the metal rod is placed between two clamping seats 3 and placed on the two driving rollers 4 in the corresponding two clamping seats 3. At the same time, the metal rod rolls against the side wall of several limiting rollers 6 on each clamping seat 3, so that the several limiting rollers 6 push the corresponding mounting seat 5 and sliding rod 51 to slide radially along the clamping seat 3 and compress the spring 52. Through the elastic action of each spring 52, the several limiting rollers 6 clamp and limit the metal rod. Then, the motor 44 is started to drive the corresponding rotating shaft 41 to rotate. Through the transmission of the two pulleys 42 and the belt 43, the two rotating shafts 41 drive the two driving rollers 4 to rotate synchronously and in the same direction, thereby driving the metal rod to rotate, so as to facilitate thermal spraying on the surface of the metal rod.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
