Specific embodiments

[0022] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0023] In the present application, unless otherwise stated, the orientation words such as "up and down, left and right, front and back, inside and outside" contained in the terms only represent the orientation of the terms in the conventional use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation on the terms.

[0024] Referring to Figs. 1-2 The positioning tool for spraying includes a base 1, one end of the base 1 is provided with a positioning groove 5, the outer end of the positioning groove 5 is inserted with a movable seat 10, the movable seat 10 is provided with a positioning boss 8, the inner end of the positioning groove 5 is provided with a notch groove 2, the bottom surface of the positioning groove 5 is provided with a guide groove 3 extending along the length direction of the base 1 and extending into the notch groove 2, the bottom surface of the guide groove 3 is provided with a vertical through rectangular port 12, the guide groove 3 is slidably provided with a pressing block 6, the bottom of the pressing block 6 is fixedly connected with a convex part 13 capable of sliding in the rectangular port 12, the lower end of the convex part 13 is provided with a screw hole, the bottom surface of the base 1 away from the one end of the positioning boss 8 is provided with a motor 14, the shaft body of the motor 14 is provided with a screw rod 17 screwed with the screw hole.

[0025] By implementing the above technical solution, when using this spraying positioning fixture, first, the base 1 is fixedly installed at the spraying station. Then, the movable seat 10 is inserted downwards from the inner end of the positioning groove 5, and then pushed outwards to insert and fix the movable seat 10 to the outer end of the positioning groove 5. Then, the motor 14 is started to rotate the screw 17 to push the pressure block 6 to press against the movable seat 10, so that the movable seat 10 is completely pressed. Finally, the workpiece to be sprayed is placed upside down on the positioning boss 8 and the spraying equipment is started to spray it. The notch 2 is used to store the pressure block 6 when placing and removing the movable seat 10. Due to this design, the positioning boss 8 in the spraying positioning fixture is detachable and can be replaced with different specifications and shapes according to different workpieces to be sprayed.

[0026] In this embodiment, guide grooves 11 are provided on both sides of the rectangular opening 12; sliding blocks 4 that can slide within the guide grooves 11 are provided on both sides of the protrusion 13. This arrangement allows the sliding blocks 4 on both sides of the protrusion 13 to slide within the guide grooves 11, increasing the compression stability of the pressure block 6.

[0027] In this embodiment, a bearing seat 18, which is rotatably connected to the end of the screw 17, is provided on the bottom surface of the base 1 at the same end position as the positioning boss 8. The bearing seat 18 provides support for the free end of the screw 17, allowing it to rotatably engage with the end of the screw 17, thereby improving the rotational stability of the screw 17.

[0028] In this embodiment, the base 1 is provided with a plurality of countersunk holes 16. The countersunk holes 16 are used to install the base 1 to the spraying station using corresponding bolts.

The support tube 15 allows the position of the base 1 to be raised, making it easier to expand the space for mounting the motor 14 at the bottom.

[0030] In this embodiment, the positioning boss 8 is a conical platform with multiple grooves 9 on its side. The grooves 9 prevent the workpiece from being pressed too tightly against the surface of the positioning boss 8, and also facilitate the emptying of the workpiece during placement, making it easier to pick up and put down the workpiece.

[0031] In this embodiment, in order to further provide a detachable connection method for the positioning boss 8, so as to facilitate the individual replacement of the positioning boss 8, a flange plate 7 is provided at the bottom of the positioning boss 8, and the flange plate 7 is bolted to the movable seat 10.

[0032] In this embodiment, the movable seat 10 is a T-shaped seat, and the outer end of the positioning groove 5 is a T-shaped groove that slides with the T-shaped seat. For example, the inner end of the positioning groove 5 is a rectangular groove, which allows the movable seat 10 to be inserted vertically downwards. After insertion, pushing the T-shaped seat outwards can insert the T-shaped seat into the T-shaped groove, and then pressing the T-shaped seat tightly by the pressure block 6.

[0033] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0034] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0035] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
