Detailed Implementation
[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.
[0018] This utility model provides a device for measuring the diameter of the injection-molded drum of a washing machine, such as... Figure 1-3 As shown, it includes a base 1 and a support plate 2, both of which are square. The support plate 2 is detachably installed on the top surface of the base 1. A positioning device 4 is provided in the center of each of the four sides of the support plate 2. The four positioning devices 4 move synchronously to push the mold on the top of the support plate 2 to the center position of the support plate 2. A bracket 6 is fixedly installed at the rear end of the base 1. An assembly area 7 is provided on the top of the bracket 6, which is vertically aligned with the center of the support plate 2. A pull rod 8 is elastically inserted into the center of the assembly area 7. A measuring ruler 9 is connected to the bottom of the pull rod 8, and the center of the measuring ruler 9 corresponds to the center of the support plate 2.
[0019] Place the tube mold to be tested on the top surface of the support plate 2. Use the four positioning devices 4 inside the base 1 to push the tube mold synchronously so that the roller mold is positioned in the center of the base 1, so that the roller corresponds to the measuring ruler 9 set on the top. Pull the pull rod 8 down to make the measuring ruler 9 fit against the top of the roller mold for measurement. This makes it easier for the measuring ruler 9 to find the midpoint of the roller mold, thereby improving the accuracy of the measurement.
[0020] In one embodiment, the top of the positioning device 4 is provided with a cross-shaped groove 41, and each side of the cross-shaped groove 41 extends out of the outer side of the positioning device 4. A four-connector air valve 42 is provided in the middle of the cross-shaped groove 41. Each side of the cross-shaped groove 41 can be detachably connected to a cylinder 43. The piston end of the cylinder 43 points to the outer side of the positioning device 4 and is connected to a connecting block 44. The top of the connecting block 44 is connected to a horizontal plate 45, and one end of the horizontal plate 45 is connected to a push plate 46.
[0021] The four-connector air valve 42 is an electronic valve. The four-connector air valve 42 is connected to four air cylinders 43 and is used to synchronously control the movement of the opening air cylinders 43. In this way, the roller mold is pushed to the middle of the support plate 2 for positioning and fixing by using the connecting block 44, the horizontal plate 45 and the push plate 46.
[0022] Furthermore, a number of balls 3 arranged in a rectangular array are movably installed on the top of the support plate 2. The balls 3 provide rolling support for the roller mold, avoiding friction between the roller mold and the support plate 2, and facilitating the positioning device 4 to push the roller mold.
[0023] Furthermore, a support roller 5 is provided around the top surface of the support plate 2. The support roller 5 corresponds to and slides in contact with the horizontal plate 45. The support roller 5 is used to support the horizontal plate 45 to prevent the horizontal plate 45 from tilting due to one end of the horizontal plate 45 and the push plate 46 being too far apart, thereby improving the stability of the horizontal plate 45 and the push plate 46.
[0024] Furthermore, a spring 10 is sleeved on the top of the pull rod 8 in the assembly area 7. A stop block 11 is fixedly connected to the top of the pull rod 8. The two ends of the spring 10 abut against the stop block 11 and the assembly area 7, respectively. In the initial state, under the elastic action of the spring 10, most of the pull rod 8 is located at the top of the assembly area 7. When measuring with the measuring ruler 9, the pull rod 8 or the measuring ruler 9 can be pulled down directly. At this time, the spring 10 is compressed by the tension until the measuring ruler 9 contacts the roller, and the inner diameter of the measuring roller mold can be observed. After the measurement is completed, the pull rod 8 or the measuring ruler 9 can be released to reset the measuring ruler 9 under the elastic force.
[0025] Furthermore, a control switch 12 is provided in the middle of one side of the bracket 6, and the control switch 12 is electrically connected to the four-connector air valve 42 to control the opening / closing of the four-connector air valve 42, which is connected to the external source.
[0026] The working principle of this utility model is as follows: The roller mold to be tested is placed on the top of the support plate 2. At this time, the four-joint air valve 42 is opened by the control switch 12 to make the cylinder 43 move synchronously. The piston end of the cylinder 43 extends and drives the horizontal plate 45 to move downward through the connecting block 44, so that the push plate 46 pushes the roller mold to move on the top surface of the support plate 2 until the four 46s abut against the roller mold. At this time, the roller mold is located in the center of the support plate 2. During measurement, the pull rod 8 or the measuring ruler 9 can be pulled downward. At this time, the spring 10 is compressed by the tension until the measuring ruler 9 contacts the roller, and the inner diameter of the roller mold can be observed and measured. After the measurement is completed, the pull rod 8 or the measuring ruler 9 is released to allow the measuring ruler 9 to return to its original position under the elastic force.
