Description

Technical Field

[0001] The utility model relates to the technical field of vernier caliper processing, in particular to a special heat treatment device for full-automatic calipers. Background Technique

[0002] A vernier caliper is a measuring tool for measuring length, inner and outer diameters, and depth. A vernier caliper consists of a main scale and a vernier scale that can slide on the main scale. The main scale of the vernier caliper needs to have good wear resistance, and necessary surface treatment is indispensable. Heat treatment is one of the economical optional solutions.

[0003] When heat-treating the main scale of a vernier caliper, a heat treatment device is used. At present, most of the heat treatment devices can only heat-treat one main scale, that is, it is clamped by a fixture and then heat-treated by a heat treatment device. Although this method can complete the heat treatment work, the work efficiency is low and needs to be improved. Moreover, after the main scale is heat-treated, it needs to be manually unloaded to a designated position with tools, which is rather troublesome and further affects the processing efficiency of the main scale. Therefore, we propose a special heat treatment device for full-automatic calipers. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Embodiment 1

[0023] Please refer to the attached Figure 1 and the attached Figure 2

[0024] A full-automatic heat treatment device for calipers, including a C-shaped frame 1, and a pressing member 2 is provided on the C-shaped frame 1;

[0025] Among them, the pressing member 2 includes a bracket 21 and two groups of pressing parts respectively movably arranged on both sides of the bracket 21. The bracket 21 is in an I-shaped shape. The two groups of pressing parts are used to symmetrically press two main scales on the C-shaped frame 1. During use, two main scales are placed manually, and then the two groups of pressing parts are respectively pressed on the opposite ends of the two main scales to press the two main scales in a horizontal posture on the C-shaped frame 1. The above-mentioned main scale is a part of the vernier caliper in the art and will not be described in detail here; Heat treatment devices 4 are movably arranged on both sides of the C-shaped frame 1 for heat-treating the two main scales respectively. In view of the short time of this heat treatment process for the size specifications of the vernier caliper, only one end of the main scale needs to be clamped and gradually moved to its outside by the heat treatment device for heat treatment.

[0026] Preferably, the pressing part of this embodiment includes:

[0027] A stud 22 is vertically rotatably arranged in the bracket 21. An active plate 23 is threadedly sleeved on the outer wall of the stud 22. The active plate 23 is slidably connected to the outer wall of the bracket 21 to ensure that the active plate 23 is stably driven to move up and down by the stud 22. A pressing block 24 is arranged at the bottom of the active plate 23; and,

[0028] A rotating member is arranged on the bracket 21 for driving the stud 22 to rotate. The rotating member is, for example, a servo motor and a reducer, and of course it is not limited to this one;

[0029] Preferably, the two groups of heat treatment devices 4 of this embodiment are respectively arranged on two sliders of a bidirectional electric guide rail 3. The bidirectional electric guide rail 3 is arranged on one side of the C-shaped frame 1. The bidirectional electric guide rail 3 is a conventional device in the art and can drive the two groups of heat treatment devices 4 to approach or move away from each other.

[0030] Preferably, the heat treatment device 4 in this embodiment is a spiral tube heating device. The spiral tube heating end of the heat treatment device 4 corresponds exactly to the main scale after pressing and fixing. After one end of the main scale is pressed and fixed, the two groups of heat treatment devices 4 are driven to approach each other by the bidirectional electric guide rail 3. Then, the spiral tube heating end of the heat treatment device 4 can be gradually sleeved on the outer side of the main scale from the other end of the main scale to perform uniform heat treatment on the main scale.

[0031] Please refer to the appendix Figure 3

[0032] Preferably, notches 101 are formed at the top of both sides of the C-shaped frame 1 in this embodiment. Support plates 5 for supporting the main scale are arranged in the two groups of notches 101. That is, one end of the main scale is fixed by the support plate 5 and the pressing member 2. The outer end of the support plate 5 is rotatably connected to the inner wall of the notch 101 through a rotating shaft. One end of the rotating shaft is connected to the output end of a rotating device 6 arranged on one side of the C-shaped frame 1. The rotating device 6 is, for example, a servo motor, which is used to drive the inner end of the support plate 5 to flip so that the support plate 5 is in a horizontal state or the inner end is in a downward inclined state. A conveyor belt device 8 is arranged in the C-shaped frame 1 and below the notch 101. The conveyor belt device 8 is a conventional device in the art. After the main scale is heat-treated, by moving the pressing part upward to a specified position and moving the heat treatment device 4 outward to a specified position, and driving the support plate 5 to rotate to an inclined state by the rotating device 6, the main scale at its top can slide down to the conveyor belt device 8, and then the main scale is conveyed to a specified position by the conveyor belt device 8.

[0033] Preferably, a cavity (not shown in the figure) is formed in the support plate 5 in this embodiment. A plurality of groups of adsorption holes for communicating with the cavity are formed at the top of the support plate 5. An adsorption tube communicating with the cavity is arranged on the support plate 5. The other end of the adsorption tube is connected to the input end of a negative pressure device 7 arranged on the C-shaped frame 1. Considering that the pressing part only presses one end of the main scale, when it detaches from the main scale, the main scale may flip and detach from the support plate 5 due to the influence of the other end being suspended. Therefore, after the main scale is heat-treated, by turning on the negative pressure device 7, an adsorption force is generated at the adsorption holes, and the main scale is adsorbed on the support plate 5. Then, the pressing part is moved upward, the heat treatment device 4 is moved outward, and the rotating device 6 drives the support plate 5 to rotate to an inclined state. At this time, the negative pressure device 7 is turned off, and then the main scale can accurately fall on the conveyor belt device 8 through the guidance of the support plate 5 to complete the unloading after heat treatment.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
