Technical Field

[0001] The utility model relates to a novel and reliable clamp changing interlocking device, belonging to the technical field of clamp changing. Background Art

[0002] When the machine tool processes different workpieces, the fixture needs to be replaced with a molded part that matches the workpiece. The existing technology completely relies on the operator's experience to manually replace the molded parts, which has a high error rate due to human errors and poses a processing risk. Utility Model Content

[0003] In order to solve the defects existing in the prior art, the purpose of the utility model is to provide a novel and reliable fixture mold change interlocking device which can accurately identify mold change parts and avoid human errors.

[0004] The technical solution of the utility model is: a novel and reliable fixture changing interlocking device, a plurality of part placement positions are arranged on the mounting bracket, each part placement position is provided with a proximity sensor for detecting the presence or absence of a part, the proximity sensor is electrically connected to the machine tool controller, a limit column is arranged on the part placement position, a limit partition is arranged between adjacent part placement positions, and an anti-misinstallation unit is also arranged on the part placement position.

[0005] The mounting bracket is provided with two parts placement positions.

[0006] The limiting posts include limiting posts a and limiting posts b, and the limiting posts a and limiting posts b have different sizes and positions on the two parts placement positions.

[0007] The anti-misinstallation unit includes four screw holes a located on the mounting bracket, three of the four screw holes a are equipped with anti-misinstallation screws a, and the conversion part is provided with four screw installation positions corresponding to the four screw holes a, one of the four screw installation positions is equipped with an anti-misinstallation screw b, and the head of the anti-misinstallation screw b is used for detachable plug-in cooperation with the screw hole a at the corresponding position.

[0008] A protective cover is arranged on the periphery of the proximity sensor.

[0009] The beneficial effects of the utility model are as follows: the model of the mold changing part is detected by the sensor and the machine tool controller with high accuracy, and the interlocking between the mold changing part and the machine tool is realized; the setting of the anti-misinstallation unit makes it impossible to put the mold changing part into place after it is placed in the wrong place, and it is easier to be found manually, thereby reducing the error rate and improving the yield rate of workpiece processing.

[0015] The following is combined with Figure 1-4 The utility model is further described as follows:

[0016] A novel and reliable fixture change interlocking device, wherein two parts placement positions are arranged on a mounting bracket 1, namely, a part placement position a8 for placing part a10 and a part placement position b9 for placing part b11, a limit partition plate 4 is arranged between the two parts placement positions, the limit partition plate 4 is used to separate the part placement positions and limit the parts at the same time, each part placement position is provided with a proximity sensor 2 for detecting the presence or absence of a part, the proximity sensor is electrically connected to a machine tool controller, when the proximity sensor 2 on the part placement position a8 detects that there is a part in the placement position, a signal is sent to the machine tool controller, the machine tool controller is a single chip microcomputer or a PLC, when the proximity sensor 2 on the part placement position b9 detects that there is no part in the placement position, no signal is sent to the machine tool The controller sends a signal, and the machine tool controller determines whether the replacement part being used is correct based on the received signal. A protective cover 7 is provided on the periphery of the proximity sensor 2 to prevent the proximity sensor 2 from being touched and damaged during the part placement process. A limit column is provided on the part placement position, and the limit column includes a limit column a5 and a limit column b6. The sizes of the limit column a5 and the limit column b6 and the positions on the two part placement positions are different. Different parts have different shapes and different limit hole positions. The limit column a5 and the limit column b6 match different replacement parts respectively. If the part is placed in the wrong position, it cannot be placed normally. After each part is placed, it is manually checked whether the part has been correctly placed. An anti-misinstallation unit 3 is also provided on the part placement position.

[0017] The anti-misinstallation unit 3 includes four screw holes a located on the mounting bracket 1, which are the first screw hole a, the second screw hole a, the third screw hole a and the fourth screw hole a. Three of the four screw holes a are equipped with anti-misinstallation screws a, that is, one of the four screw holes a is empty and divided into four situations. The four situations correspond to the detection of four different types of replacement parts. The replacement parts are provided with four screw installation positions corresponding to the four screw holes a. One of the four screw installation positions is equipped with an anti-misinstallation screw b. The head of the anti-misinstallation screw b is used for detachable plug-in cooperation with the screw hole a at the corresponding position. The anti-misinstallation screw b is inserted into the empty screw hole a for correct assembly. If the assembly is wrong, the anti-misinstallation screw b will interfere with the anti-misinstallation screw a in the screw hole a, and the replacement part cannot be assembled in place, reminding the staff to handle it.

[0018] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
