Description

Technical Field

[0001] The utility model relates to the technical field of counters, and particularly relates to a heat-insulating counter. Background Art

[0002] A counter is an instrument that makes a measured object move horizontally to drive a detection wheel to rotate. After the detection wheel drives the rotating shaft to rotate, the rotation angle of the rotating shaft is detected to calculate the length of the measured object. It has high measurement accuracy and is widely used in various production fields.

[0003] In the rolling production process that requires heating, after rolling and forming, it needs to be cut according to the length. To ensure the accuracy of the cutting length, the counter needs to be directly attached to the surface of the high-temperature workpiece to be processed for measurement. However, since the measurement accuracy of the counter highly depends on the shape of the rotating shaft and the detection accuracy of the electronic components, long-term contact with high-temperature objects will cause heat to be transferred along the contact surface to the rotating shaft and the electrical components, changing the performance of the electronic components inside the electronic components and affecting the accuracy of the electrical signal transmission. Therefore, a heat-insulating counter is needed. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a heat-insulating counter, which can avoid heat transfer to the electrical components.

[0005] The technical solution of the utility model is realized as follows:

[0006] A heat-insulating counter includes a mounting frame, a counting wheel, a rotating shaft, a coupling and a heat-insulating mechanism. The middle part of the rotating shaft is rotatably installed on the mounting frame. The counting wheel is installed at one end of the rotating shaft. The other end of the rotating shaft is axially connected to the measuring shaft of the electrical component through the coupling. The counting wheel rolls on the surface of the workpiece to be measured. The heat-insulating mechanism is sleeved outside the coupling, and the heat-insulating mechanism is a hollow structure.

[0007] Preferably, the heat-insulating mechanism includes a cylindrical side wall, and a plurality of through holes are provided on the side wall.

[0008] Preferably, the heat-insulating mechanism further includes spokes protruding from one end of the side wall and a connecting ring protruding from the other end of the side wall. The spokes are fixed on the mounting frame, and the connecting ring is fixed on the electrical component.

[0013] Preferably, the flange seat is made of aluminum material.

[0014] Preferably, the connecting bar is pivotally connected to the fixed seat.

[0015] Preferably, heat dissipation holes are provided in the middle of the connecting bar.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] The heat-insulating counter includes a mounting bracket, a counter wheel, a rotating shaft, a coupling, and a hollow heat-insulating mechanism. During use, the translating workpiece drives the counter wheel to rotate, the counter wheel drives the measuring rotating shaft to rotate, the rotating shaft drives the measuring shaft of the electrical component to rotate through the coupling, and the electrical component measures by reading the motion state of the measuring shaft to obtain the moving distance of the workpiece during this process. During this process, the heat of the counter wheel is transferred to the rotating shaft, and the heat of the rotating shaft is transferred to the coupling.

[0025] See Figure 1 and Figure 2 , a heat-insulating length counter, which includes a mounting bracket 1, a length measuring wheel 2, a rotating shaft 3, a coupling 4, and a heat-insulating mechanism 5. The middle part of the rotating shaft 3 is rotatably installed on the mounting bracket 1. The length measuring wheel 2 is installed at one end of the rotating shaft 3. The other end of the rotating shaft 3 is axially connected to the measuring shaft 61 of the electrical component 6 through the coupling 4. The length measuring wheel 2 rolls on the surface of the workpiece to be measured. The heat-insulating mechanism 5 is sleeved outside the coupling 4, and the heat-insulating mechanism 5 is a hollow structure. During use, the translated workpiece drives the length measuring wheel 2 to rotate. The length measuring wheel 2 drives the measuring rotating shaft 3 to rotate. The rotating shaft 3 drives the measuring shaft 61 of the electrical component 6 to rotate through the coupling 4. The electrical component 6 measures by reading the motion state of the measuring shaft 61, thereby obtaining the moving distance of the workpiece during this process, which is convenient for cutting according to the length. During this process, the heat of the length measuring wheel 2 is transferred to the rotating shaft 3, and the heat of the rotating shaft 3 is transferred to the coupling 4. Since the hollow heat-insulating mechanism 5 is sleeved outside the coupling 4, the coupling 4 dissipates heat by itself and dissipates heat through the hollow space of the heat-insulating mechanism 5, thereby blocking the heat transferred from the workpiece from reaching the electrical component 6 and avoiding the heat from being transferred into the electrical component 6, achieving the effect of heat insulation.

[0026] In this embodiment, the electrical component 6 is a decoder, and the decoder measures by reading the motion state of the measuring shaft 61, thereby obtaining the moving distance of the workpiece during this process.

[0027] Specifically, refer to Figure 3 , the heat insulation mechanism 5 includes a cylindrical side wall 51, and a plurality of through holes 511 are provided on the side wall 51. The cylindrical side wall 51 is sleeved outside the coupling 4, and the plurality of through holes 511 on the side wall 51 form a hollow structure of the heat insulation mechanism 5, and the heat of the coupling 4 is dissipated through the plurality of through holes 511, so as to avoid heat transfer to the electrical component 6.

[0028] Furthermore, refer to Figure 3 , the heat insulation mechanism 5 further includes spokes 52 protruding from one end of the side wall 51 and a connecting ring 53 protruding from the other end of the side wall 51. The spokes 52 are fixed on the mounting bracket 1, and the connecting ring 53 is fixed on the electrical component 6. The spokes 52 and the connecting ring 53 are respectively used to connect the mounting bracket 1 and the electrical component 6, so that the heat insulation mechanism 5 is located between the mounting bracket 1 and the electrical component 6, playing a role in blocking heat transfer.

[0029] Preferably, the length measuring wheel 2 is made of aluminum material, and the heat absorbed by the length measuring wheel 2 from the surface of the workpiece can be naturally dissipated through the aluminum characteristics of the length measuring wheel 2 itself, reducing the heat transferred from the length measuring wheel 2 to the rotating shaft 3, and can further improve the heat insulation effect.

[0030] Preferably, refer to Figure 2 , a plurality of weight reduction holes 21 are provided on the hub of the length measuring wheel 2. As an accurate measuring instrument, the length measuring device needs to avoid errors as much as possible. The greater the mass of the length measuring wheel 2, the greater the inertia, and it is more likely to generate errors when starting or stopping. The setting of the weight reduction holes 21 can reduce the mass of the length measuring wheel 2, thereby reducing the error caused by inertia. Furthermore, the plurality of weight reduction holes 21 are evenly distributed on the hub of the length measuring wheel 2, which can maintain the balance of the length measuring wheel 2 while reducing the inertia error. In this embodiment, four weight reduction holes 21 are evenly distributed on the hub of the length measuring wheel 2. In fact, the number and size of the weight reduction holes 21 can be adjusted according to needs.

[0031] In this embodiment, refer to Figure 2 , the mounting bracket 1 includes a fixed seat 11, a connecting strip 12 and a flange seat 13. The fixed seat 11 and the flange seat 13 are respectively installed at both ends of the connecting strip 12, and the rotating shaft 3 is rotatably installed on the mounting bracket 1 through the flange seat 13. After the length measuring wheel 2 transfers heat to the rotating shaft 3, the rotating shaft 3 transfers heat to the flange seat 13 and the coupling 4, and dissipates heat to the outside through the flange seat 13 and to the connecting strip 12, thereby reducing the heat transfer amount from the rotating shaft 3 to the coupling 4.

[0032] Preferably, the flange base 13 is made of aluminum material. The aluminum flange base 13 is more conducive to heat dissipation of the flange base 13. During the measurement process, the heat absorbed by the length measuring wheel 2 from the surface of the workpiece is first dissipated naturally through the aluminum characteristics of the length measuring wheel 2 itself. Part of the heat of the length measuring wheel 2 is transferred to the rotating shaft 3, and the heat of the rotating shaft 3 is transferred to the flange base 13 and the coupling 4. The flange base 13 dissipates heat externally and to the connecting bar 12. The coupling 4 dissipates heat through its own structure and through the hollow space of the heat insulation mechanism 5, thereby isolating the heat transferred by the workpiece from the electrical component 6 and preventing the heat from being transferred to the electrical component 6, achieving the effect of heat insulation.

[0033] Preferably, the connecting bar 12 is pivotally connected to the fixed seat 11, which facilitates disengaging the contact between the length measuring wheel 2 and the workpiece to be measured to stop the measurement. By rotating the connecting bar 12, the connecting bar 12 rotates around the fixed seat 11, and the length measuring wheel 2 can be driven to rotate away from the workpiece to be measured, and the measurement stops.

[0034] Preferably, the middle part of the connecting bar 12 is provided with heat dissipation holes 121. When the flange base 13 transfers heat to the connecting bar 12, the heat dissipation holes 121 in the middle of the connecting bar 12 are conducive to accelerating the heat dissipation of the connecting bar 12.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
