Description

Technical Field

[0001] This utility model relates to the technical field of assisting in the spraying of paint onto saw blades, and in particular to a quick-install saw blade spraying fixture. Background Technology

[0002] The structure of saw blade 1 produced in a certain workshop is as follows: Figures 1-2 As shown, multiple tooth seats 2 are fixed on the outer edge of the saw blade 1 along its circumference. The tooth seats 2 are evenly distributed on the saw blade 1 and integrally formed with the saw blade 1. An alloy cutter head 3 is welded to the end face of each tooth seat 2. A central hole 4 is opened in the center of the saw blade 1, and a keyway 5 is opened on the inner wall of the central hole 4. The alloy cutter heads 3 on the saw blade 1 can alternately cut metal profiles. In order to improve the service life of the saw blade 1, the process requires that a layer of paint be sprayed on the top and bottom surfaces of a batch of saw blades 1, and it is also required that the paint not be sprayed onto the alloy cutter heads 3 and tooth seats 2.

[0003] The method used by the workers in the workshop to spray paint the top and bottom surfaces of the saw blade 1, without spraying the alloy cutter head 3 and the tooth holder 2, is as follows: S1. The worker takes out a saw blade 1 that is to be painted and wraps multiple layers of plastic film around the outside of the first alloy blade head 3 and tooth holder 2 that are connected as one piece. That is, the alloy blade head 3 and tooth holder 2 are wrapped with the plastic film. S2. The worker repeats step S1 once to wrap multiple turns of plastic film around the outside of the second integrated alloy cutter head 3 and tooth holder 2. S3. Repeat step S2 multiple times to wrap plastic film around the outside of each of the alloy blade head 3 and tooth holder 2 that are connected as one piece in the first saw blade 1. S4. The worker sprays a layer of paint onto the top surface of the saw blade 1 using a spray gun. After spraying, the worker flips the saw blade 1 so that the bottom surface of the saw blade 1 faces upward. Then, the worker sprays a layer of paint onto the bottom surface of the saw blade 1 using a spray gun, thus achieving the final result of spraying a layer of paint onto both the top and bottom surfaces of the saw blade 1. Since the alloy cutter head 3 and the tooth holder 2, which are connected as one piece, are both wrapped with plastic film, the paint will not be sprayed onto the alloy cutter head 3 and the tooth holder 2 during the painting process, thus meeting the process requirements. S5. The worker tears off all the plastic films on the saw blade 1. S6. Workers can repeat steps S1 to S5 multiple times to spray paint on the top and bottom surfaces of a batch of saw blades 1.

[0004] However, although the method used in the workshop is able to spray paint the top and bottom surfaces of the saw blade 1 without spraying paint onto the alloy cutter head 3 and tooth holder 2, the workers still reported the following technical defects: Since a saw blade 1 has as many as 22 alloy cutting heads 3, it is necessary to perform the plastic film wrapping operation 22 times to completely cover the 22 alloy cutting heads 3 connected as one piece and the tooth holder 2. The entire operation is done manually by the workers, which not only increases the workers' workload, but also prolongs the spraying time of the saw blade 1, thereby reducing the spraying efficiency of the saw blade.

[0005] Therefore, there is an urgent need for a spraying fixture that can greatly reduce the workload of workers and greatly improve the efficiency of spraying saw blades. Utility Model Content

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description: like Figures 3-9As shown, a quick-assembly saw blade spraying fixture includes a pad 6, a support column 7 fixed on the top surface of the pad 6, a positioning column 8 fixed on the top surface of the support column 7, the positioning column 8 cooperating with the center hole 4 of the saw blade 1, a strip key 9 fixed along its axial direction on the column surface of the positioning column 8, the strip key 9 cooperating with the keyway 5 of the saw blade 1, a plurality of columns 10 distributed outside the support column 7 fixed on the top surface of the pad 6, a fixing ring 11 coaxial with the positioning column 8 fixed between the top surfaces of each column 10, a plurality of radially distributed rods 12 slidingly passing through the fixing ring 11, each rod 12 corresponding to the tooth seat 2 of the saw blade 1, a protective shell 13 fixed on the inner end of the rod 12, and a connecting rod 14 hinged to the outer end of the rod 12 via a first pin, the rod 12 and the connecting rod 14 forming an obtuse angle.

[0015] A movable ring 15 is provided on the outside of the fixed ring 11. Multiple hinge seats 16, corresponding to the connecting rod 14, are fixed on the inner wall of the movable ring 15 along its circumference. A second pin 17 is hinged between the hinge seat 16 and the outer end of the connecting rod 14. Multiple guide holes, corresponding to the rod 12, are opened inside the fixed ring 11, and the rod 12 is slidably installed within the guide holes.

[0016] Four uprights 10 are fixed on the pad 6 and distributed outside the positioning post 8. The inner end face of the protective shell 13 is an arc-shaped surface 18 that matches the outer cylindrical surface of the saw blade 1.

[0017] The working process of this utility model is as follows: S1, the worker takes out a... Figures 1-2 The saw blade 1 shown is to be painted. S2. Place the center hole 4 of the saw blade 1 onto the outside of the positioning post 8 from top to bottom, and place the keyway 5 of the saw blade 1 onto the outside of the strip key 9 from top to bottom. Then place the bottom surface of the saw blade 1 on the top surface of the support post 7. Since the positioning post 8 and the center hole 4 are engaged, and the strip key 9 and the keyway 5 are engaged, the positioning of the saw blade 1 is achieved. Figure 10 As shown, at this time, each tooth seat 2 on the saw blade 1 is opposite to each protective shell 13; S3. The worker manually rotates the movable ring 15 to make it rotate counterclockwise around the axis of the support column 7. The direction of rotation of the movable ring 15 is as follows: Figure 11 As shown by the middle arrow, the movable ring 15 drives the connecting rods 14 to move synchronously. The connecting rods 14 drive the rods 12 to move radially toward the axis of the support column 7. The rods 12 drive the protective shell 13 to move toward the toothed seat 2 opposite to it. When the worker can no longer move the movable ring 15, the saw blade 1 enters the painting station, as shown. Figure 12As shown, at this time, the inner cavity 19 of the protective shell 13 fits perfectly over the outside of the alloy blade head 3 and the tooth seat 2 that are connected as one piece, and the arc-shaped surface 18 of the protective shell 13 just abuts against the outer cylindrical surface of the saw blade 1. S4. The worker points the paint spray gun nozzle toward the top surface of the saw blade 1 and then turns on the paint spray gun so that the paint sprayed from the nozzle is applied to the top surface of the saw blade 1. After spraying for a period of time, a layer of paint can be applied to the top surface of the saw blade 1. Since the protective shell 13 is fitted over the alloy cutter head 3 and tooth holder 2 which are connected as one piece, the paint will not be applied to the alloy cutter head 3 and tooth holder 2. S5. The worker manually reverses the direction of rotation of the movable ring 15, causing it to rotate clockwise around the axis of the support column 7. The direction of rotation of the movable ring 15 is as follows: Figure 13 As shown by the middle arrow, the movable ring 15 drives each link 14 to move synchronously. The link 14 drives the rod 12 to move away from the support column 7. The rod 12 drives the protective shell 13 to move away from the tooth seat 2. The protective shell 13 gradually separates from the tooth seat 2. When it is observed that the protective shell 13 is completely separated from the tooth seat 2, the worker stops turning the movable ring 15. S6. The worker removes the saw blade 1 from the positioning post 8, then flips the saw blade 1 so that the top surface of the saw blade 1 faces upward; then the worker repeats the operation of steps S2 to S4 once to spray a layer of paint on the bottom surface of the saw blade 1. S7. Workers repeat steps S1 to S6 multiple times to spray a layer of paint on the top and bottom surfaces of multiple saw blades 1.

[0018] As can be seen from steps S2 to S4, the worker only needs to first position the saw blade 1 on the positioning post 8, and then the worker turns the movable ring 15 counterclockwise. Within a short period of time, a protective shell 13 is fitted onto the outside of the integrated alloy blade head 3 and tooth holder 2, allowing the saw blade 1 to quickly enter the painting station. Therefore, compared to the painting method in the workshop, this painting fixture eliminates the need for workers to wrap plastic film around the integrated alloy blade head 3 and tooth holder 2 one by one. This not only greatly reduces the worker's workload but also shortens the painting time of the saw blade 1, thus significantly improving the painting efficiency of the saw blade.

[0019] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
