Technical Field

[0001] The utility model relates to the technical field of tripod arm processing, in particular to a processing and clamping process device for a tripod arm of an agricultural machinery. Background Art

[0002] The tripod of agricultural machinery is made of aluminum alloy. Aluminum alloy has the characteristics of light texture, high hardness and not easy to deform. It has been widely used in agricultural machinery production. It fixes the suspension and wheel position and plays a role in stability.

[0003] The tripod needs to be fixed during the processing, and further processing can be carried out after it is fixed. In the current existing technology, a clamp is matched with a screw and a slide rod. By shaking the screw, the clamps are brought closer to each other to clamp the tripod. This operation is convenient and fast, but due to its special structure, ordinary clamps cannot wrap its concave and convex surfaces when clamping, which causes the tripod to be offset in the clamp during processing and production.

[0004] Therefore, it is particularly important to improve the existing agricultural machinery tripod processing and clamping process device, design a new agricultural machinery tripod processing and clamping process device to solve the above-mentioned technical defects, and improve the practicability of the overall agricultural machinery tripod processing and clamping process device.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0025] A processing and clamping device for a tripod arm of an agricultural machine, comprising an operating platform 1, and further comprising:

[0026] The processing unit is used to clamp the tripod arm during processing, and the processing unit includes a clamping assembly 2, and the clamping assembly 2 is located on the top of the operating table 1.

[0027] For further information, see Figure 1-Figure 5 In this embodiment, the clamping assembly 2 includes a fixing plate 201, a fixing seat 202, a threaded rod 203, a supporting plate 204, a connecting rod 205 and a clamping plate 206. The fixing plate 201 is installed on the top of the operating table 1, the fixing seat 202 is installed on the top of the fixing plate 201, the threaded rod 203 is installed inside the fixing seat 202, the supporting plate 204 is installed on one end of the threaded rod 203 away from the fixing seat 202, the connecting rod 205 is installed on the outside of the supporting plate 204, and the clamping plate 206 is installed on one side of the connecting rod 205 away from the supporting plate 204. When the tripod arm needs to be processed, the tripod arm is placed on the top of the operating table 1, and the threaded rod 203 is rotated to achieve a threaded reaction between the threaded rod 203 and the fixed seat 202, so that the threaded rod 203 can move inside the fixed seat 202, and at the same time drive the support plate 204 to approach the tripod arm, so that the splint 206 and the tripod arm are fitted together, and when the splint 206 contacts the uneven surface, it drives the connecting rod 205 to swing, thereby driving the splint 206 to tilt, so that the splint 206 clamps the tripod arm.

[0028] Among them, see Figure 1-Figure 5 In this embodiment, a mounting platform 207 is installed on the top of the fixing plate 201 and outside the fixing seat 202, and slide grooves 208 are provided on the left and right sides of the mounting platform 207. A slide bar 209 is installed on the side of the support plate 204 away from the connecting rod 205. The support plate 204 is connected to the mounting platform 207 through the slide bar 209. The movement of the support plate 204 simultaneously drives the slide bar 209 to slide inside the slide groove 208, wherein the slide bar 209 is limited by the slide groove 208, so that the support plate 204 moves in a straight line when moving, thereby preventing the support plate 204 from deflecting.

[0029] Second, see Figure 1-Figure 5 In this embodiment, a first connecting seat 210 is installed on the front and rear sides of the side close to the support plate 204, a second connecting seat 211 is installed between the first connecting seats 210, and a third connecting seat 212 is installed on the outside of the connecting rod 205 away from the support plate 204. Through the design of the first connecting seat 210, the second connecting seat 211 and the third connecting seat 212, the connecting rod 205 can be rotated, thereby enhancing the linkage between the support plate 204 and the splint 206.

[0030] Furthermore, please see Figure 1-Figure 5 In this embodiment, grooves are symmetrically opened inside the second connecting seat 211, and a slider is installed inside the groove. The connecting rod 205 is connected to the second connecting seat 211 through the slider. The connecting rod 205 swings, thereby driving the slider to slide in the groove, so that the second connecting seat 211 cooperates with the connecting rod 205 to swing.

[0031] For further information, see Figure 1-Figure 5 In the present embodiment, a comb strip 213 is installed on the side close to the splint 206, and the comb strip 213 is slidably connected to the inside of the splint 206. A baffle 214 is installed in the middle of the inside of the splint 206, and a ball 215 is installed on the side of the baffle 214 away from the comb strip 213. When the splint 206 fits the trident, the splint 206 squeezes the trident, and the comb strip 213 slides inside the splint 206, so that the comb strip 213 wraps the uneven surface of the trident, and the baffle 214 is driven to squeeze the ball 215, and the ball 215 reacts on the baffle 214, so that the comb strip 213 can wrap the trident steadily.

[0032] For further information, see Figure 1-Figure 5In this embodiment, a clamping column 216 is installed at the front end of the baffle 214, and a waist groove 217 is opened at the front end of the clamping plate 206 at a position corresponding to the clamping column 216. The clamping column 216 and the waist groove 217 are adapted for use. When the tripod arm needs to be released, the clamping column 216 is pressed and slid in the waist groove 217, so that the comb strip 213 is squeezed through the baffle 214 to achieve the reset of the comb strip 213.

[0033] In this embodiment, the implementation scenario is specifically as follows: when the tripod arm needs to be processed, the tripod arm is placed on the top of the operating table 1, and the threaded rod 203 is rotated to achieve a threaded reaction between the threaded rod 203 and the fixed seat 202, so that the threaded rod 203 is moved inside the fixed seat 202, and at the same time drives the support plate 204 to approach the tripod arm, and at the same time drives the slide bar 209 to slide inside the slide groove 208, wherein the slide bar 209 is limited by the slide groove 208, so that the support plate 204 moves in a straight line when moving, preventing the support plate 204 from moving. 204 is offset, so that the splint 206 and the trident are fitted together, and when the splint 206 contacts the uneven surface, it drives the connecting rod 205 to swing, thereby driving the splint 206 to tilt, so that the splint 206 squeezes the trident, and the comb strip 213 slides inside the splint 206, so that the comb strip 213 wraps the uneven surface of the trident, and drives the baffle 214 to squeeze the ball 215, and the ball 215 reacts on the baffle 214, so that the comb strip 213 stably wraps the trident.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
