Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments.
The overall structure of the device is as shown in figures 1 and 2, the main body of the three-station totally-enclosed cylinder sand blasting machine is divided into three stations, namely a sand blasting station and two feeding and discharging stations, wherein the two feeding and discharging stations are positioned on two sides of the sand blasting station. The three stations are specifically a left station 1, a middle station 2 and a right station 3. The left station 1 and the right station 3 are stations for taking and placing workpieces; the middle station 2 is a sand blasting cabin, and the parts of the left station 1 or the right station 3 enter the sand blasting cabin of the middle station 2 for sand blasting operation. A plurality of spray guns 4 arranged in a matrix manner are arranged in the sand blasting cabin 2, the spray guns 4 can swing left and right parallel to the axis of a cylindrical workpiece, the spray guns are in the prior art, and redundant description is omitted here.
As shown in fig. 3 to 4, a conveyor 5, a workpiece mounting rack 6, a cylindrical workpiece 7, a V-shaped guide rail 8, a gate 9, a cylinder 10, and a housing 11 are provided inside the left station 1 and the right station 2. Four corners of the tool mounting frame 6 are provided with four rollers 15, and the tool mounting frame 6 is provided with an electric roller 16 and a driven roller 17. The conveyor belt 5 is fixed on the left and right transmission shafts of the sand blasting machine, and the V-shaped guide rail 8 is fixed on the front and rear walls of the sand blasting machine. The tool mounting frame 6 is supported on the V-shaped guide rail through four rollers 15, is fixedly connected with the conveyor belt 5, and drives the workpiece mounting frame 6 to move linearly through the conveyor belt 5.
The tool mounting frame 6 is further provided with a motorized roller 16 and a driven roller 17, the cylindrical workpiece 7 is placed on the motorized roller 16 and the driven roller 17, and the motorized roller 16 rolls during sand blasting, so that the cylindrical workpiece 7 placed on the motorized roller is driven to roll, and the whole circumferential direction can be sprayed.
A gate 9 and an air cylinder 10 are respectively arranged at the left side and the right side of the sand blasting cabin, and the air cylinder 10 can drive the gate 9 to move up and down. When the sand blasting is started, the air cylinder 10 pushes the gate 9 to move downwards to completely close the sand blasting cabin 2.
As shown in figures 1-3, a left door 12 is arranged at the left station of the shell 11, a middle door 13 is arranged in the sand blasting cabin, and a right door 14 is arranged at the right station. The left door 12, the middle door 13, the right door 14 and the shell 11 form a totally-enclosed structure, so that dust can be prevented from coming out during sand blasting.
The working principle is as follows:
first, the left door 12 of the left station 1 is opened, the cylindrical workpiece 7 is placed on the workpiece mounting frame 6, and the left door 12 is closed. Then, the right door 14 of the right station 3 is opened, the cylindrical workpiece 7 is placed on the workpiece mounting frame 6, and the right door 14 is closed.
Starting a sand blasting machine, under the automatic program control, a left air cylinder 10 and a right air cylinder 10 of the sand blasting cabin 2 push a gate 9 to move upwards, then a left workpiece mounting rack 6 carries a cylindrical workpiece 7 to enter the sand blasting cabin 2 under the drive of a conveyor belt 5, and the gate 9 moves downwards to close the sand blasting cabin 2. The sand blasting machine starts sand blasting, the spray guns 4 arranged in a matrix shape swing left and right parallel to the axis of the cylindrical workpiece, and meanwhile the electric roller 16 drives the cylindrical workpiece 7 to roll.
After the left workpiece is subjected to sand blasting, under the automatic program control, a left air cylinder 10 and a right air cylinder 10 of the sand blasting cabin 2 push a gate 9 to move upwards, the sand blasting cabin 2 is opened, and a left workpiece mounting frame 6 carries a cylindrical workpiece 7 to come out of the sand blasting cabin 2 under the driving of a conveyor belt 5 and return to a left station 1; meanwhile, the right workpiece mounting bracket 6 carries the cylindrical workpiece 7 into the blasting chamber 2 under the drive of the conveyor 5, and then the gate 9 moves downward to close the blasting chamber 2. And starting the sand blasting operation of the workpiece on the right side.
During the sand blasting operation of the workpiece on the right side, the left door 12 of the left station 1 is opened, the cylindrical workpiece 7 which is subjected to sand blasting is taken out, a new workpiece to be subjected to sand blasting is put in, and the left door 12 is closed. After the right workpiece is subjected to sand blasting, under the automatic control of a program, the cylindrical workpiece 7 of the right station 3 returns to the right station 3, and meanwhile, a newly-installed workpiece of the left station 1 enters the sand blasting cabin 2 to perform sand blasting operation. The operation is circulated in this way.
The invention discloses a three-station totally-enclosed sand blasting machine, which is a sand blasting machine with a brand-new layout and structure. It has the following advantages:
1. the three stations are arranged on the left and right sides of the sand blasting cabin, the workpiece is loaded and unloaded, the middle sand blasting cabin can continuously blast sand, and the production efficiency is high.
2. The workpiece mounting frame is provided with the electric roller and the driven roller to support the workpiece, the electric roller drives the cylindrical workpiece to roll in the sand blasting process, the whole circumferential surface can be blasted well at one time, the sand blasting is uniform, and the quality is good.
3. Pneumatic gates are arranged on two sides of the sand blasting cabin, the sand blasting cabin gate is closed during sand blasting, and dust can be prevented from running to the left station and the right station.
4. The whole shell of the sand blasting machine is totally closed, so that dust can be prevented from coming out.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
