Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery parts processing, and in particular to a clamp for processing agricultural machinery parts. Background Technology

[0002] The harrow blade is a key component in agricultural tillage machinery (such as disc harrows). It is usually a thin-walled disc-shaped structure with a certain concavity and sharp cutting edges for cutting and breaking up soil.

[0003] The manufacturing process of rake blades typically involves multiple steps, including turning, drilling, heat treatment, and grinding the cutting edges. Among these, the performance of the fixture directly determines the machining accuracy, efficiency, and yield in the turning, drilling, and especially the grinding of the cutting edges processes.

[0004] Currently, the commonly used clamping methods for processing rake blades in the industry mainly have the following problems: Rake blades vary in diameter and center hole size depending on their model and application. Existing fixtures are mostly specialized fixtures, typically only suitable for one or a few specifications of rake blades. When producing multiple models of rake blades, frequent fixture changes and adjustments are required, leading to extended production preparation time, reduced equipment utilization, and increased production costs.

[0005] Traditional clamps (such as a simple three-jaw chuck with a flat pressure plate) are prone to workpiece deformation when clamping thin-walled rake blades due to uneven or concentrated clamping force, which seriously affects the final machining accuracy, especially the symmetry and straightness of the cutting edge. Furthermore, when spraying wear-resistant coatings onto the rake blades, the fixed rake blades are easily sagged by gravity, forming "sags" that result in excessive thickness in some areas, leading to the "orange peel" phenomenon. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0007] Therefore, one objective of this utility model is to provide a clamp for processing agricultural machinery parts. The clamping mechanism drives the support arm to move, thereby opening the support arm. This enables the clamping of different types of rake blades with uniform clamping force and self-centering clamping. After clamping, the support mechanism can drive the rake blade to rotate, so that the wear-resistant coating will not drip when it is sprayed.

[0008] To achieve the above objectives, the first aspect of this utility model provides a jig for processing agricultural machinery parts, comprising: a support mechanism, a transmission structure, and clamping plates, wherein the transmission structure includes a sleeve and a threaded rod, wherein the sleeve is sleeved on one end of the support mechanism; one end of the threaded rod is rotatably disposed on the support mechanism, and the other end passes through the sleeve and extends thereto; a plurality of clamping plates are respectively movably disposed on the support mechanism, and the inner walls of the plurality of clamping plates are respectively hinged to the outer wall of the sleeve.

[0009] In addition, the jig for processing agricultural machinery parts proposed above according to this utility model may also have the following additional technical features: Specifically, the support mechanism includes a support rod, a support base, and a limiting block. The support rod is rotatably mounted on the support base, and multiple transmission grooves are formed on the outer wall of the support rod. The sleeve is fitted onto the end of the support rod where the transmission grooves are formed. The limiting block is fixedly mounted on the support rod on one side of the sleeve, and multiple sliding grooves are formed at equal intervals on the limiting block.

[0010] Specifically, one end of the sleeve is provided with a threaded hole; one end of the threaded rod extends through the threaded hole; multiple transmission blocks are provided on the inner wall of the sleeve; the multiple transmission blocks are respectively located inside the transmission groove.

[0011] Specifically, the extended end of the threaded rod is provided with a rectangular block and a throttle, wherein the rectangular block is fixedly mounted on the threaded rod; and the throttle is sleeved on the rectangular block.

[0012] Specifically, each clamping plate includes an arc-shaped wall and a hinge rod, wherein an arc-shaped block and a slider are respectively provided on the arc-shaped wall; the arc-shaped block is fixedly disposed on the outer wall of the arc-shaped wall; the slider is fixedly disposed on one end of the arc-shaped wall and is located in the groove; one end of the plurality of hinge rods is respectively hinged to the inner wall of the arc-shaped wall, and the other end is respectively inclinedly hinged to the outer wall of the sleeve.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The clamp for processing agricultural machinery parts of the present invention can move the hinge rod of the movable sleeve to move the arc wall along the slide groove, thereby enabling it to self-center and clamp different types of rake blades with uniform clamping force, without damaging the thin wall of the rake blade. Furthermore, by rotating the support rod, the sleeve and the arc wall can be rotated together, thus preventing dripping when spraying the wear-resistant layer.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] The following describes a jig for processing agricultural machinery parts according to an embodiment of the present invention, with reference to the accompanying drawings.

[0019] like Figures 1-6 As shown, the jig for processing agricultural machinery parts according to this utility model embodiment may include: a support mechanism 1, a transmission structure 2, and a clamping plate 3.

[0020] The transmission structure 2 includes a sleeve 21 and a threaded rod 22.

[0021] Among them, the sleeve 21 is sleeved on one end of the support mechanism 1, one end of the threaded rod 22 is rotatably mounted on the support mechanism 1, and the other end passes through the sleeve 21 and extends thereto. Multiple clamping plates 3 are respectively movably mounted on the support mechanism 1, and the inner walls of the multiple clamping plates 3 are respectively hinged to the outer wall of the sleeve 21.

[0022] Specifically, when staff need to clamp the rake blade, they only need to fit the center hole of the rake blade onto the outer wall of the clamping plate 3.

[0023] At this time, by rotating the threaded rod 22, the sleeve 21 is moved along the support mechanism 1. The moving sleeve 21 will drive the multiple clamping plates 3 hinged on it to move along the support mechanism 1, thereby abutting against the rake blade and forming the purpose of clamping the rake blade.

[0024] At this time, the rotating support mechanism 1 can drive the transmission structure 2 and multiple clamping plates 3 to rotate together, thereby causing the rake blades clamped on the multiple clamping plates 3 to rotate together.

[0025] like Figure 3 As shown, the jig for processing agricultural machinery parts according to this utility model embodiment may include: a support mechanism 1 including a support rod 11, a support base 12 and a limiting block 13.

[0026] The support rod 11 is rotatably mounted on the support base 12, and multiple transmission grooves 111 are provided on the outer wall of the support rod 11. The sleeve 21 is sleeved on the end of the support rod 11 where the transmission grooves 111 are provided. The limiting block 13 is fixedly mounted on the support rod 11 on one side of the sleeve 21, and multiple sliding grooves 131 are provided on the limiting block 13 at equal intervals.

[0027] It should be noted that the support base 12 described in this embodiment is provided with mounting holes, through which the support base 12 can be fixed on the workbench, thereby enabling the support base 12 to perform its supporting function.

[0028] Specifically, rotating the support rod 11 will cause the limiting block 13 mounted on it to rotate together, thereby causing its sliding groove 131 and transmission groove 111 to drive multiple clamping plates 3 and sleeves 21 to rotate respectively.

[0029] It should be noted that the rotation of the support rod 11 can be achieved by a drive device such as a drive motor (not shown in the figure).

[0030] like Figure 4 and Figure 5 As shown, the jig for processing agricultural machinery parts according to this utility model embodiment may include: a threaded hole 211 at one end of a sleeve 21, a threaded rod 22 extending through the threaded hole 211 at one end, and a plurality of transmission blocks 212 provided on the inner wall of the sleeve 21, with the plurality of transmission blocks 212 respectively located inside the transmission groove 111.

[0031] The threaded rod 22 has a rectangular block 221 and a throttle 222 respectively at its extended end. The rectangular block 221 is fixedly mounted on the threaded rod 22, and the throttle 222 is sleeved on the rectangular block 221.

[0032] It should be noted that the threaded rod 22 described in this embodiment is threadedly connected in the threaded hole 211, so that when the threaded rod 22 rotates, it can drive the sleeve 21 to move along the threaded rod 22.

[0033] Specifically, when the support rod 11 rotates, it will drive the sleeve 21 to rotate together through the transmission block 212 located inside the transmission groove 111.

[0034] The handle 222, which is fitted onto the rectangular block 221, can be removed when the rake blade is fitted onto the multiple clamping plates 3, thereby preventing the handle 222 from obstructing the rake blade.

[0035] like Figure 6 As shown, the jig for processing agricultural machinery parts according to this utility model embodiment may include: each clamping plate 3 includes an arc-shaped wall 31 and a hinge rod 32.

[0036] Among them, the arc-shaped wall 31 is provided with an arc surface block 311 and a slider 312. The arc surface block 311 is fixedly installed on the outer wall of the arc-shaped wall 31, and the slider 312 is fixedly installed on one end of the arc-shaped wall 31, and the slider 312 is located in the slide groove 131. One end of the multiple hinge rods 32 is respectively hinged to the inner wall of the arc-shaped wall 31, and the other end is respectively inclinedly hinged to the outer wall of the sleeve 21.

[0037] It should be noted that the number of each set of hinge rods 32 shall not be less than two, so as to prevent the arc-shaped wall 31 from tilting during transmission.

[0038] Specifically, when the sleeve 21 moves, it pushes or pulls the arc-shaped wall 31 in the slide groove 131 through the hinge rod 32, thereby clamping and releasing the rake blade. The arc-shaped block 311 set on the arc-shaped wall 31 can support the concave surface of the rake blade and prevent the edge of the rake blade from contacting the support mechanism 1.

[0039] In summary, the clamp for processing agricultural machinery parts of this utility model can move the sleeve so that its hinge rod drives the arc wall to move along the slide groove, thereby enabling it to self-center and clamp different types of rake blades with uniform clamping force, without damaging the thin wall of the rake blade. Furthermore, by rotating the support rod, the sleeve and the arc wall can be rotated together, thus preventing dripping when spraying the wear-resistant layer.
