Technical Field

[0001] The utility model belongs to the technical field of automobile parts production, and in particular relates to a tooling error prevention device adopting a gas detection principle. Background Art

[0002] Aluminum alloy die-castings are widely used in automotive lubrication systems and cooling systems. Aluminum alloy die-castings are produced in large quantities and in many types. Similar products are prone to mixing when they are received, which requires screening of the mixed materials.

[0003] The existing machine tool product error prevention mainly relies on manual observation of the appearance and subsequent process verification. Although it can be identified, it is easy to miss the inspection. At the same time, it is inefficient and costly, and it is difficult to meet the needs of large-scale low-cost manufacturing. For this reason, we proposed a tooling error prevention device that uses the gas detection principle to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a tooling error prevention device adopting a gas detection principle, so as to solve the problems existing in the background technology.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Embodiment 1:

[0024] like Figure 1-Figure 3 As shown, a tool error prevention device using the gas detection principle includes a machine tool 100, a sensor 101 is arranged outside the machine tool 100, the sensor 101 is electrically connected to the machine tool 100, a first air inlet pipe 102 is connected to one side of the sensor 101, a workbench is placed on one side of the machine tool 100, a tool 103 is installed on the upper end of the workbench, a product 104 is installed on the upper end of the tool 103, a detection component is arranged on the upper end of the workbench, and the detection component is located below the product 104;

[0025] The detection component includes a base 200, which is installed on the upper end of the workbench. A mounting groove 201 is opened at the upper end of the base 200. A cylinder body 202 is sealed inside the mounting groove 201. A piston 203 is sealed and slid inside the cylinder body 202. A support rod 204 is fixed to the middle of the upper end of the piston 203. A lifting component that cooperates with the piston 203 is provided on the outer side of the base 200. A T-shaped bracket 205 is sleeved on the outer side of one end of the support rod 204 that passes through the cylinder body 202. A through groove is opened on one side of the upper end of the T-shaped bracket 205. A detection column 206 is slidably provided inside the through groove. The lower end of the detection column 206 is connected to an inflation tube 207. A vent 208 is opened on the upper outer side of the detection column 206, and the vent 208 is connected to the sensor 101 through an air pipe.

[0026] The lifting assembly includes a lower air pipe 300, which is fixedly connected to the outer side of the base 200 and communicated with the inside of the mounting groove 201. A vent hole 301 communicated with the mounting groove 201 is provided on the lower wall of the cylinder body 202, and an upper air hole 302 is provided on the upper outer side of the cylinder body 202. The lower air pipe 300 and the upper air hole 302 are commonly connected to a solenoid valve 303, and a second air intake pipe 304 is connected to one side of the solenoid valve 303.

[0027] The sensor 101 can detect the detection signal, so that the machine tool 100 can determine the difference of the product 104 to be tested according to the signal fed back by the sensor 101. The tooling 103 can more conveniently install the product 104. The product 104 is divided into multiple types due to different shapes. The piston 203 can slide up and down inside the cylinder 202, thereby indirectly pushing the support rod 204, the T-shaped bracket 205 and the detection column 206 to move, so that the air outlet of the detection column 206 can abut against the product 104. The second air inlet pipe 304 can pass gas, which can be divided into two paths when passing through the solenoid valve 303. The distribution allows the gas to pass into the cylinder 202 and the installation groove 201, and allows the piston 203 to move up and down under the push of the gas, thereby indirectly pushing the air outlet of the detection column 206 to abut against the product 104 to be tested, so that the sensor 101 can receive the signal, which is convenient for subsequent data comparison and distinguishing products 104 of different specifications.

[0028] When testing the product 104: the product 104 is installed on the upper end of the tooling 103, and gas is introduced into the first air inlet pipe 102 and the air pipe. The gas transported from the first air inlet pipe 102 directly enters the sensor 101 to generate a signal P1, and the gas transported from the air pipe enters the detection column 206. Since the product 104 has various specifications, when it is installed on the tooling 103, some products 104 will be tightly abutted against the air outlet of the detection column 206 to prevent the internal gas of the detection column 206 from leaking. Therefore, these gases will be transported to the sensor 101 through the air pipe through the air vent 208 to generate a signal P2. In this way, the sensor 101 can detect the relationship between the signal P1 and the signal P2, and then feed it back to the machine tool 100, so that the staff can more conveniently select products 104 of different specifications;

[0029] When signal P1 = signal P2: the machine tool 100 will judge OK, which means that the product 104 to be tested blocks the air outlet of the testing column 206, so that after the testing mechanism is retracted, the machine tool 100 can continue to operate normally;

[0030] When signal P1 < signal P2: the machine tool 100 will determine NG, which means that the product 104 to be tested does not block the air outlet of the testing column 206. In this way, after the testing mechanism is retracted, the machine tool 100 will stop, allowing the staff to quickly remove the product 104.

[0031] In this embodiment, by utilizing the appearance difference of the detection product 104, the signal of the product 104 is detected by relying on the detection column 206 that can float up and down, so as to quickly identify the product 104, thereby improving the efficiency of manual sorting and preventing missed detection.

[0032] Embodiment 2:

[0033] Based on the first embodiment, other structures of the misplacement device are further described, such as Figure 1-Figure 3 As shown, a stopper 305 is provided on the outer side of the detection column 206 , a spring 306 is provided between the lower end of the stopper 305 and the upper end of the T-shaped bracket 205 , and the spring 306 is sleeved on the outer side of the detection column 206 .

[0034] A guide column 307 is fixed to the upper end of the base 200 , and the T-shaped bracket 205 is slidably sleeved on the outer side of the guide column 307 .

[0035] Two bolts 308 are threadedly connected to the outer side of the support rod 204 , and the two bolts 308 are respectively abutted against the upper and lower ends of the T-shaped bracket 205 .

[0036] In this embodiment, the block 305 can more conveniently install the spring 306 so that the spring 306 is located at the upper end of the T-shaped bracket 205, so that the detection column 206 can slide up and down inside the through groove, thereby achieving a close contact between the air outlet of the detection column 206 and the lower end of the product 104, thereby ensuring the accuracy of the detection data of the sensor 101 and preventing malfunctions.

[0037] When the piston 203 drives the support rod 204 to move up and down, the guide column 307 can limit the shaking of the T-shaped bracket 205, thereby ensuring that the up and down movement is vertical, and further ensuring that there is no gap when the air outlet of the detection column 206 abuts against the product 104, thereby affecting the data detected by the sensor 101.

[0038] By tightening the lower bolt 308, the position of the T-shaped bracket 205 on the support rod 204 can be limited. Then, by tightening the upper bolt 308 and cooperating with the lower bolt 308, the T-shaped bracket 205 can be fixed, thereby facilitating the subsequent movement of the detection column 206.
