Description

Technical Field

[0001] This utility model particularly relates to a clamping mechanism for coating spraying. Background Technology

[0002] When spraying paint on plate-shaped or frame-shaped workpieces (such as door panels and window frames) of different widths, the force application point of the clamping mechanism needs to be adjusted laterally accordingly to ensure that the clamping force acts on the effective load-bearing part of the workpiece and avoid the workpiece tipping over or deforming due to improper clamping point.

[0003] A common method for achieving lateral adjustment of the clamping point in existing technologies is to install a sliding pressure block on a horizontally positioned guide rod and lock the pressure block to the guide rod using bolts or other components. However, this structure has the following drawbacks: the locking bolt relies entirely on the friction between the bolt head and the pressure block to maintain its position. Under long-term vibration conditions, this friction may be insufficient, causing the pressure block to slip along the guide rod, resulting in unexpected displacement of the clamping point, posing a safety hazard and affecting processing quality.

The clamping assembly includes a handle assembly mounted on the base 1 via a rotating shaft 4, and the end of the handle assembly has a strip-shaped hole 5 along its length. A pressure hammer 6 passes through the strip-shaped hole 5, with an upper anti-dislodgement cap 7 threadedly connected to its upper part and a lower anti-dislodgement cap 8 threadedly connected to its lower part. The upper pressure seat 9 and the lower pressure seat 10 are slidably sleeved on the outer side of the pressure hammer 6 and the upper and lower sides of the strip hole 5, respectively, and the bearing surface of the lower anti-detachment cap 8 can press against the lower pressure seat 10; the upper pressure seat 9 and the lower pressure seat 10 are connected by at least one pair of first elastic elements 11 distributed on both sides of the handle assembly; after loosening the upper anti-detachment cap 7 and the lower anti-detachment cap 8, the upper pressure seat 9 and the lower pressure seat 10 are moved to make them move in opposite directions, so as to drive the pressure hammer 6 to slide along the strip hole 5 to the designated pressing position, and the pressure hammer 6 presses the sprayed part 1-1 onto the base 1 by pressing the auxiliary pressure plate 3.

[0022] Furthermore, the handle assembly is provided with a slide 51 that communicates with the strip hole 5, and the upper pressure seat 9 and the lower pressure seat 10 are provided with protrusions 510 that cooperate with the slide 51, so that the upper pressure seat 9 and the lower pressure seat 10 can slide along the length direction of the handle assembly.

[0023] Furthermore, a hinge seat 12 is fixedly provided on the base 1, and the handle assembly is rotatably connected to the hinge seat 12 through the rotating shaft 4; a second elastic element 13 is also connected between the hinge seat 12 and the handle assembly.

[0028] Furthermore, the cover plate 21 is fixed to the positioning plate 2 by screws.

[0029] The working principle of this utility model is as follows: As an embodiment 1, the coating spraying clamping mechanism of this application includes a base 1, a positioning plate 2 installed at the left end of the base 1, and an auxiliary pressure plate 3 rotatably connected to the right end via a hinge pin 1-2. Thus, the auxiliary pressure plate 3 and the positioning plate 2 together form a clamping station. It should be noted that a complete automated or semi-automated coating spraying equipment typically consists of multiple functional modules working together, mainly including: a workpiece conveying module, a clamping module, and a spraying execution module. This utility model is an improvement on the "clamping module." The spraying execution module is not shown in the figures. It can be selected using conventional methods such as a spray gun mounted on a robotic arm or a fixed spray gun array. Once a workpiece 1-1 is reliably fixed by the clamping mechanism described in this utility model, the spraying execution module can perform spraying operations on the surface of the workpiece in a static and stable state under the command of the control system. Since the main protection and core improvement of this utility model lie in the clamping mechanism itself, the accompanying drawings and the following embodiments will focus on showing the structural details of the clamping mechanism itself.

[0030] A hinge seat 12 is fixed to the base 1 by screws. The handle assembly is rotatably connected to the hinge seat 12 via a rotating shaft 4. The linkage part 141 of the handle assembly is rotatably engaged with the rotating shaft 4, and the grip part 142 extends downward. A strip-shaped hole 5 is provided at the end of the linkage part 141. The upper end of the pressure hammer 6 is machined with external threads and screwed with an upper anti-slip cap 7, and the lower end is also machined with external threads and screwed with a lower anti-slip cap 8. An upper pressure seat 9 and a lower pressure seat 10 are respectively fitted on the upper and lower sides of the strip-shaped hole 5. Both are block structures, and their backs are provided with protrusions 510 that cooperate with the slide rail 51, so that the upper and lower pressure seats can slide stably along the length of the handle assembly without deflection. The upper pressure seat 9 and the lower pressure seat 10 are connected by two springs distributed on the left and right sides of the strip-shaped hole 5.

[0031] During operation, first loosen the upper anti-dislodgement cap 7 and the lower anti-dislodgement cap 8. Simultaneously, the operator pulls the upper pressure seat 9 upward and the lower pressure seat 10 downward, moving them away from the linkage part 141. Then, move along the direction of the strip hole 5, causing the pressure hammer 6, which passes through it, to slide freely along the strip hole 5. After moving the pressure hammer 6 to the designated position corresponding to the auxiliary pressure plate 3, tighten the upper and lower anti-dislodgement caps 8 to lock the pressure hammer 6 in that position. The handle assembly is pressed down, causing it to rotate around the pivot 4. Since the pressure hammer 6 is fixed to the handle assembly via a structure such as an anti-detachment cap, it moves upwards accordingly. Then, the sprayed part 1-1 is placed on the clamping station, and the handle assembly is lifted upwards. Under the action of leverage, the handle assembly rotates around its hinge point with the base 1, thereby causing the pressure hammer 6 to press against the auxiliary pressure plate 3. The auxiliary pressure plate 3 then presses the sprayed part 1-1 against the base 1. The first elastic elements 11 are symmetrically distributed on both sides of the handle assembly. This symmetrical layout ensures that the forces acting on the upper pressure seat 43 and the lower pressure seat 44 are always in a balanced state. When the pressure hammer 6 transmits the pressing force to the lower pressure seat 44 through the lower anti-detachment cap 8, the first elastic elements 11 on both sides are compressed synchronously and uniformly, and the resulting reaction force also acts symmetrically on the upper and lower pressure seats. This symmetrical force system structure fundamentally eliminates the tendency for the pressure seat and pressure hammer 6 to deflect laterally or slide due to unilateral force. The second elastic element 13 is connected between the hinge seat 12 and the linkage part 141 of the handle, and the reset torque it provides is transmitted to the entire handle assembly through the rotating shaft 51. This torque is ultimately converted into the vertical pressing force of the pressure hammer 6 on the auxiliary pressure plate 3.

[0032] Based on the above technical solution, this application provides a limiting boss 121 on the hinge seat 12. When the handle assembly is raised downward to the near-horizontal maximum opening position, its grip portion 142 end will abut against the limiting boss 121, thereby preventing the handle assembly from over-reversing.

[0033] Based on the above technical solution, this application provides a limiting part 20 on the side of the positioning plate 2 for positioning the edge of the sprayed part 1-1. A cover plate 21 is detachably fixed to the upper end of the positioning plate 2 by screws, and the cover plate 21 is used to press the sprayed part 1-1.

[0034] This invention replaces the traditional single bolt friction locking method with a combination of structures including an upper anti-detachment cap 7, a lower anti-detachment cap 8, an upper pressure seat 9, a lower pressure seat 10, and a first elastic element 11. The pressure hammer 6 is firmly clamped between the upper pressure seat 9 and the lower pressure seat 10, effectively eliminating the risk of accidental slippage of the clamping point under long-term vibration conditions, and fundamentally solving the safety hazards and unstable processing quality problems existing in the prior art.

[0035] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
