Description

Technical Field

[0001] The invention relates to a mechanical processing equipment, in particular to a spray processing equipment for producing a jack chassis. Background Art

[0002] A jack is a small and light lifting device that uses a rigid lifting piece as a working device to lift heavy objects through a small stroke of the top support or bottom claws. In order to ensure the stability of the jack, a relatively large disc-shaped chassis is usually set at the bottom of the jack. In the actual production and processing of the jack chassis, in order to ensure that its surface is not easily oxidized and corroded, it is necessary to add a layer of paint on its large surface in the form of spraying, but due to its relatively large area, it is difficult to complete the traditional spraying processing mode. Summary of the invention

[0024] like Figures 1 to 6 As shown, a spray processing equipment for jack chassis production includes a workbench 1 and a hanger 2 fixed on the workbench 1; a placement groove 1a is set in the center of the workbench 1.

[0025] A main control component is installed on the upper part of the hanger 2; the main control component is respectively connected to a reversing component and a driving component; the reversing component is connected to a guide rod 21; the driving component includes a large disc 4, and a slot 2a slidably matched with the large disc 4 is opened in the middle of the hanger 2, and a slide groove 4a is provided on the left and right parts of the large disc 4, and a slider 5 is slidably installed in each slide groove 4a, and a spray gun 6 is installed at the bottom of each slider 5.

[0026] The main control component includes a motor 7 installed on the hanger 2, the motor 7 is connected to an incomplete gear 8, and the incomplete gear 8 is respectively meshed with a left gear 9 and a right gear 10; the left gear 9 and the right gear 10 are respectively connected to a left shaft 11 and a screw 12 installed on the hanger 2 through bearings.

[0027] The reversing assembly includes a second incomplete gear 13 installed on the left shaft 11 and a first sub-shaft 14 and a second sub-shaft 15 installed on the hanger 2 through bearings; the first sub-shaft 14 is respectively installed with a third incomplete gear 16 and a sub-gear 17; the sub-gear 17 is meshed with the left gear 9; the second sub-shaft 15 is installed with an output gear 28 that can mesh with both the second incomplete gear 13 and the third incomplete gear 16.

[0028] The reversing assembly includes a No. 1 bevel gear 18 installed at the lower part of the No. 2 split shaft 15 and a guide frame 27 installed on the workbench 1; the No. 1 bevel gear 18 is meshed with a No. 2 bevel gear 19, and the front end surface of the No. 2 bevel gear 19 is provided with a protrusion 19a at an eccentric position; a movable frame 20 is vertically slidably installed on the guide frame 27, and a matching groove 20a for horizontally sliding the protrusion 19a is opened on the left part of the movable frame 20, and a guide rod 21 is connected to the right side of the movable frame 20.

[0029] The second bevel gear 19 is connected to a side shaft 22 mounted on the hanger 2 through a bearing seat.

[0030] The bottom of the lead screw 12 is mounted on the large disc 4 through a bearing; the reversing assembly also includes a movable column 23 mounted on the lead screw 12 through a thread, and a turning frame 24 is fixedly connected to the upper part of the movable column 23. The turning frame 24 has a slot 24a adapted to the guide rod 21.

[0031] The left and right sides of the movable column 23 are both hingedly connected with a pair of connecting rods 25 ; each pair of connecting rods 25 is hingedly connected with a follower frame 26 connected with the corresponding slider 5 on the side away from the movable column 23 .

[0032] In the present invention, an upper cover 29 is also installed on the upper part of the hanger 2. The placement groove 1a is circular and its diameter corresponds to the diameter of the jack chassis to be sprayed. The two connecting rods 25 of each pair are parallel to each other, that is, each pair of connecting rods 25, the movable column 23 and the corresponding follower frame 26 can form a parallelogram mechanism.

[0033] During specific use, the jack chassis needs to be placed in the placement groove 1a on the workbench 1 with the large surface facing upward.

[0034] When in use, the motor 7 drives the incomplete gear 8 to rotate at a constant speed, so that the incomplete gear 8 is alternately meshed with the left gear 9 and the right gear 10, and the following four steps can be performed cyclically and sequentially:

[0035] In the first step, when the incomplete gear 8 and the right gear 10 are meshed for the first time, the right gear 10, the movable column 23, the large disc 4 and the two spray guns 6 can all rotate 180 degrees, that is, the two spray guns 6 are controlled to spray an inner ring area on the large surface of the jack chassis.

[0036] In the second step, when the incomplete gear 8 and the left gear 9 are meshed for the first time, the second incomplete gear 13 and the output gear 28 are meshed for transmission, and the third incomplete gear 16 and the output gear 28 are not meshed. In this state, the second bevel gear 19 rotates 180 degrees clockwise and the protrusion 19a rotates from the upper limit position to the lower limit position on the second bevel gear 19, so that the movable frame 20 and the guide rod 21 can slide downward, so that the guide rod 21 is inserted into the slot 24a; that is, the guide rod 21 and the turning frame 24 are vertically slidably matched.

[0037] In the third step, when the incomplete gear 8 and the right gear 10 are meshed for the second time, under the transmission action of the screw nut, the turning frame 24 and the movable column 23 slide vertically downward, and under the transmission action of the connecting rod 25, the follower frame 26, the slider 5 and the spray gun 6 can slide in the direction away from the center of the movable column 23, so that the spray gun 6 slides a distance from the radial inner side of the jack chassis to the radial outer side of the jack chassis.

[0038] Step 4: When the incomplete gear 8 and the left gear 9 are meshed for the second time, the second incomplete gear 13 and the output gear 28 are not meshed, and the third incomplete gear 16 and the output gear 28 are meshed for transmission. In this state, the second bevel gear 19 rotates 180 degrees counterclockwise and the protrusion 19a rotates from the lower limit position to the upper limit position on the second bevel gear 19, so that the movable frame 20 and the guide rod 21 can slide upward, so that the guide rod 21 slides out of the slot 24a; that is, the guide rod 21 and the turning frame 24 are released from the sliding fit; so as to facilitate the next control of the spray gun 6 for rotation spraying.

[0039] By executing the above four steps in a loop, the spraying process on all areas on the large surface of the jack chassis can be effectively achieved.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
