Measuring device for processing iron handicrafts

Abstract

This utility model discloses a measuring device for processing iron crafts, including a base and a ring-shaped workpiece. A ring-shaped positioning seat is fixed in the middle of the base. Positioning members are hinged to both sides of the bottom of the positioning seat, and a control member is located in the middle of the positioning member. Two movable members are hinged to the bottom of the control member, with one end of the movable member hinged to the positioning member. A first measuring caliper is also provided on both sides of the positioning seat, with one end of the first measuring caliper hinged to the positioning seat. A second measuring caliper is slidably mounted inside the first measuring caliper. When measuring the ring-shaped workpiece, pressing down on the control member causes the positioning member that first contacts the ring-shaped workpiece to push it outwards until the other positioning member also contacts the ring-shaped workpiece. Since the inner wall of the ring-shaped workpiece is arc-shaped, when the positioning member can no longer be pressed down, it indicates that the positioning member is now on the center line of the ring-shaped workpiece, and the dimensions of the ring-shaped workpiece can then be measured.

Description

Technical Field

[0001] This utility model relates to the technical field of iron craft processing equipment, and in particular to a measuring device for iron craft processing. Background Technology

[0002] Iron handicrafts are handicrafts or ornaments made primarily of iron through forging, welding, and surface treatment processes. They combine practicality and artistry. During the processing, it is usually necessary to measure the dimensions of the handicrafts.

[0003] For ring-shaped iron handicrafts, the main focus is on measuring their inner and outer diameters. Existing measurement methods typically involve using vernier calipers, which require manual adjustment of the measuring heads at both ends. However, this method necessitates manually locating the center line of the handicraft, and any deviation in the center line will prevent accurate diameter measurement. Utility Model Content

[0004] The purpose of this invention is to provide a measuring device for processing iron crafts in order to solve the above-mentioned problems.

[0005] The technical solution of this utility model is implemented as follows:

[0006] This utility model provides a measuring device for processing iron crafts, including a base and an annular workpiece. An annular positioning seat is fixed in the middle of the base, and the annular workpiece is sleeved on the outside of the positioning seat. Positioning members for abutting the annular workpiece are hinged on both sides of the bottom of the positioning seat, and a control member is slidably arranged in the middle of the positioning member. Two movable members are hinged at the bottom of the control member. The movable members are hinged to the end facing the positioning member. A first measuring caliper is slidably arranged on both sides of the positioning seat. The end of the first measuring caliper connected to the positioning seat is hinged. A second measuring caliper is slidably arranged inside the first measuring caliper.

[0007] In one embodiment, a limit knob is rotatably provided on the top of the control member, and limit members are fixed on both sides of the limit knob. The limit members are slidably abutted against the top of the positioning seat, and the control member has a groove for the limit members to slide downward.

[0008] In one embodiment, the movable element is tilted towards the outside.

[0009] In one embodiment, a first magnetic absorbing piece is fixed inside the first measuring caliper, and a second magnetic absorbing piece is fixed at one end of the second measuring caliper facing the first measuring caliper, wherein the second magnetic absorbing piece and the first magnetic absorbing piece are attracted to each other by opposite polarities.

[0010] In one embodiment, a plurality of annularly distributed anti-slip strips are fixed on the outer surface of the limiting knob.

[0011] In one embodiment, the end of the positioning member facing the movable member is wrapped with a silicone pad.

[0012] The advantages or beneficial effects of the above technical solutions include at least the following:

[0013] When measuring a ring-shaped workpiece, this invention involves placing the workpiece on the outside of the positioning seat and pressing down on the control component. This causes the movable component to rotate the positioning component outward. Since both the movable and positioning components rotate outward symmetrically, as the control component slides down, the positioning component that first contacts the ring-shaped workpiece will push it outward until the positioning component on the other side also contacts the ring-shaped workpiece. At this point, the control component continues to slide down. Because the inner wall of the ring-shaped workpiece is arc-shaped, if the positioning component is not at the center line of the ring-shaped workpiece at this time, the ring-shaped workpiece will shift and adjust its position under the pressure of the positioning component. When the positioning component can no longer be pressed down, it indicates that the positioning component is now at the center line of the ring-shaped workpiece. Then, the first and second measuring calipers can be flipped and unfolded to measure the dimensions of the ring-shaped workpiece. Attached Figure Description

[0025] Reference Figures 1-3A measuring device for processing iron handicrafts includes a base 1 and an annular workpiece 2. An annular positioning seat 3 is fixedly mounted in the middle of the base 1. The annular workpiece 2 is sleeved on the outside of the positioning seat 3. Positioning members 4 for abutting the annular workpiece 2 are hinged to both sides of the bottom of the positioning seat 3. A control member 5 is slidably mounted in the middle of the positioning member 4. Two movable members 6 are hinged to the bottom of the control member 5. The ends of the movable members 6 facing the positioning members 4 are hinged. First measuring calipers 7 are slidably mounted on both sides of the positioning seat 3. The end of the first measuring caliper 7 connected to the positioning seat 3 is hinged. The ruler 7 has a sliding second measuring caliper 8. With this configuration, when measuring the dimensions of a ring-shaped workpiece 2 (i.e., a ring-shaped iron craft), the ring-shaped workpiece 2 is placed on the outside of the positioning seat 3. At this point, there is no need to specifically adjust the position of the ring-shaped workpiece 2; that is, there is no need to specifically position the positioning seat 3 at the exact center of the ring-shaped workpiece 2. Then, pressing down on the control element 5 causes the two movable parts 6 to flip outwards. At this time, the movable parts 6 can drive the positioning element 4 to flip outwards at one end, forming a triangle with the movable parts 6, the positioning element 4, and the positioning seat 3. If the positioning seat 3 is not located at the exact center of the ring-shaped workpiece 2, one side of the positioning element 4 will be affected. First, the control member 5 touches the inner wall of the annular workpiece 2. At this time, the positioning member 4 on the other side is still a certain distance from the inner wall of the annular workpiece 2. Since the control member 5 can only slide in the longitudinal direction, the moving parts 6 and the positioning members 4 on both sides rotate outward in a symmetrical manner when the control member 5 slides. Therefore, as the control member 5 continues to press down, the positioning member 4 that is abutting against the annular workpiece 2 will push the annular workpiece 2 until the positioning member 4 on the other side also abuts against the inner wall of the annular workpiece 2. Since the inner wall of the annular workpiece 2 is arc-shaped, if the positioning member 4 is not at the center line of the annular workpiece 2 at this time, the annular workpiece 2 will be pressed by the positioning member 4. The position will be adjusted downwards. When the control piece 5 can no longer be pressed down, it means that the positioning piece 4 is now on the center line of the annular workpiece 2. That is, when the two positioning pieces 4 can no longer be flipped outwards, the two positioning pieces 4 are already on the center line of the annular workpiece 2. At this time, slide and flip the first measuring caliper 7, which is on the same longitudinal plane as the positioning piece 4. If the length is not enough, slide and unfold the second measuring caliper 8 to measure the size of the annular workpiece 2 on the center line. In this way, the unfolded length of the first measuring caliper 7 and the second measuring caliper 8 on both sides plus the distance between the two first measuring calipers 7 is the size that needs to be measured.

[0026] In one specific embodiment, the mass of the positioning member 4, the movable member 6, and the control member 5 decreases sequentially, and the hinge joint between the positioning member 4 and the movable member 6 is damped. In this way, the center of gravity of the entire connecting mechanism is at the bottom, and the control member 5 will not slide down due to the center of gravity and press against the movable member 6 and the positioning member 4 in a natural state, which is convenient to use.

[0027] In one specific embodiment, the outer side of the positioning seat 3 is provided with a mounting groove for mounting the first measuring caliper 7. When the measuring device is not in use, the first measuring calipers 7 on both sides are attached to the outer side of the positioning seat 3, with one end of the first measuring caliper 7 connected to the positioning seat 3 facing downward and the other end facing upward. The first measuring caliper 7 is embedded in the mounting groove. This not only prevents the second measuring caliper 8 from sliding out due to gravity, but also prevents the first measuring caliper 7 from being unable to unfold due to insufficient distance between the positioning seat 3 and the annular workpiece 2 when in use. When the annular workpiece 2 is positioned and ready for measurement, the first measuring caliper 7 is first slid upward, so that the end of the first measuring caliper 7 hinged to the positioning seat 3 slides to the top of the positioning seat 3. At this time, the first measuring caliper 7 extends upward, and then flips downward to unfold the first measuring caliper 7. The length is used to determine whether the second measuring caliper 8 has slid out. Then the first measuring caliper 7 is slid downward, so that the first measuring caliper 7 or the second measuring caliper 8 abuts against the top of the annular workpiece 2, which facilitates the measurement of dimensions.

[0028] Reference Figure 1 and Figure 3 The top of the control component 5 is provided with a limit knob 9, and limit components 10 are fixed on both sides of the limit knob 9. The limit components 10 are slidably abutted against the top of the positioning seat 3. The control component 5 is provided with a groove 11 for the limit components 10 to slide downward. With this setting, the sliding of the control component 5 can be further restricted to prevent it from sliding downward on its own due to gravity. When the measuring device is not in use, the limit components 10 abut against the top of the positioning seat 3. At this time, the control component 5 cannot slide down. When it is necessary to position the annular workpiece 2, the limit knob 9 is rotated so that the limit components 10 slide to the groove 11. At this time, the control component 5 can be pressed down, and the limit components 10 slide downward in the groove 11.

[0029] Reference Figure 3 The movable part 6 is tilted towards the outside. With this setting, when the control part 5 is pressed down, the movable part 6 will flip directly outward due to the tilted guide, so as to drive the positioning part 4 to flip outward, thus avoiding the movable part 6 and the positioning part 4 from getting stuck when the control part 5 is pressed down because they are on the same straight line.

[0030] Reference Figure 4 The first measuring caliper 7 has a first magnetic absorbing piece 12 fixed inside, and the second measuring caliper 8 has a second magnetic absorbing piece 13 fixed at the end facing the first measuring caliper 7. The second magnetic absorbing piece 13 and the first magnetic absorbing piece 12 are attracted by opposite polarities. With this setting, when the second measuring caliper 8 is not manually slid out, it will be fixed inside the first measuring caliper 7 due to the attraction between the first magnetic absorbing piece 12 and the second magnetic absorbing piece 13, which further improves the stability of the connection between the first measuring caliper 7 and the second measuring caliper 8 and prevents the second measuring caliper 8 from sliding out on its own when the first measuring caliper 7 is flipped.

[0031] In one specific embodiment, when the first magnetic attractant 12 and the second magnetic attractant 13 attract each other, the tail of the second magnetic attractant 13 protrudes beyond the tail of the first magnetic attractant 12 by a certain distance. In this way, when the second magnetic attractant 13 slides out, its protruding tail can be used as the force point, making it convenient to pull out the second magnetic attractant 13.

[0032] Reference Figure 1 and Figure 3 The outer surface of the limit knob 9 is provided with several ring-shaped anti-slip strips 14, which prevent slippage when rotating the limit knob 9.

[0033] Reference Figure 2 and Figure 3 The end of the positioning component 4 facing the movable component 6 is wrapped with a silicone pad 15. This setting reduces the pressure on the annular workpiece 2 when it is pressed by the positioning component 4, and prevents the inner wall of the annular workpiece 2 from being damaged by friction from the positioning component 4.

[0034] In one specific embodiment, after measuring the dimensions of the annular workpiece 2, the second measuring caliper 8 is first slid into the interior of the first measuring caliper 7, so that the first magnetic accumulator 12 and the second magnetic accumulator 13 are attracted. Then, the first measuring caliper 7 is flipped upward so that it is flush with the mounting groove on the outside of the positioning seat 3. Then, the first measuring caliper 7 is slid downward and stored in the mounting groove. Then, the control member 5 is slid upward to completely store the movable member 6 and the positioning member 4. The limiting knob 9 is just located at the top of the positioning seat 3. At this time, the limiting knob 9 is rotated so that the limiting member 10 is disengaged from the slide groove 11 and abuts against the top of the positioning seat 3, thus completing the storage process of the entire measuring device. Finally, the annular workpiece 2 is taken out.

[0035] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
