Description

Technical Field

[0001] This utility model relates to the field of dial indicator printing technology, and in particular to a mechanism for improving the printing accuracy of dial indicators. Background Technology

[0002] The spindle head machine, widely used in the machining field, is renowned for its high precision and efficiency. In its structure, the Z-axis lead screw plays a crucial role, driving the spindle's vertical movement to achieve precise workpiece machining.

[0003] When assembling the Z-axis lead screw, the dial indicator base is usually fixed directly to the end of the lead screw for accuracy calibration. The top of the lead screw is usually located inside the motor housing, meaning the dial indicator base needs to be installed inside the motor housing. If there is insufficient space inside the motor housing, it cannot be fixed, and the dial indicator cannot be used for accuracy calibration, affecting the normal use of the device. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a mechanism for improving the accuracy of dial indicator marking, so as to solve the current technical problem that the motor base cannot be fixed due to insufficient internal space, and thus cannot mark the accuracy of the dial indicator.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A mechanism for improving the printing accuracy of a dial indicator includes a Z-axis bearing housing and a Z-axis motor housing, wherein a lead screw is rotatably arranged between the Z-axis bearing housing and the Z-axis motor housing.

[0008] A motor plate is provided at the end of the Z-axis motor housing away from the Z-axis bearing housing. A coupling is provided at the end of the lead screw located in the inner cavity of the Z-axis motor housing. A mandrel is fixedly connected to the end of the coupling away from the lead screw. A dial indicator is fixed to the end of the mandrel away from the coupling. A dial indicator is installed at the mounting end of the dial indicator.

[0009] As an improved technical solution, the Z-axis bearing housing is rotatably connected to the lead screw through a bearing installed in its inner cavity, the Z-axis motor housing is rotatably connected to the lead screw through a bearing installed in the lower part of its inner cavity, and a bearing cover for shielding the bearing is installed at the end of the Z-axis motor housing away from the motor plate.

[0010] As an improved technical solution, a Z-axis anti-collision adhesive is fixed at one end of the Z-axis bearing housing near the lead screw, and a notch is provided on the peripheral surface of the Z-axis anti-collision adhesive.

[0011] As an improved technical solution, the bearing cover is fixed with a Z-axis anti-collision adhesive II on one end face away from the Z-axis motor seat, and a circular hole for the lead screw to pass through is provided at the center of the Z-axis anti-collision adhesive II.

[0012] As an improved technical solution, the dial indicator base includes a base mounted on the end of the mandrel away from the coupling, a vertical frame fixed on the base, a swing arm mounted on the front side of the vertical frame, and a dial indicator fixed at the bottom end of the swing arm.

[0013] As an improved technical solution, the lead screw, coupling, and mandrel are coaxial.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. This utility model mounts the dial indicator base on the mandrel, and the mandrel and the lead screw are linked by a coupling. This increases the number of couplings and the mandrel. If the internal space of the Z-axis motor base is insufficient to mount the dial indicator base, the dial indicator base can be fixed on the coupling to measure the dial indicator accuracy. This solves the problem of insufficient internal space of the Z-axis motor base to mount the dial indicator base. Furthermore, the lead screw, coupling, and mandrel are in a coaxial state, which is equivalent to the dial indicator base being directly mounted on the top of the lead screw, ensuring the accuracy of the dial indicator measurement.

[0016] 2. In this utility model, Z-axis anti-collision rubber II installed at the bottom of the bearing cap and Z-axis anti-collision rubber I installed at the top of the Z-axis bearing seat are both installed on the moving area of ​​the lead screw, which plays a protective role and prevents damage caused by collision between objects.

[0028] like Figures 1 to 4As shown in the figure, this embodiment provides a mechanism for improving the dial indicator printing accuracy. This mechanism for improving the dial indicator printing accuracy includes a Z-axis bearing seat 1 and a Z-axis motor seat 3. An observation window is provided on the Z-axis motor seat 3. A lead screw 2 is rotatably arranged between the Z-axis bearing seat 1 and the Z-axis motor seat 3.

[0029] A motor plate 4 is provided at the end of the Z-axis motor housing 3 away from the Z-axis bearing housing 1. A coupling 32 is provided at the end of the lead screw 2 located in the inner cavity of the Z-axis motor housing 3. A mandrel 33 is fixedly connected to the end of the coupling 32 away from the lead screw 2. A dial indicator 5 is fixed to the end of the mandrel 33 away from the coupling 32. A dial indicator 6 is installed at the mounting end of the dial indicator 5.

[0030] like Figure 1 and Figure 3 As shown in the figure, in this embodiment, the Z-axis bearing housing 1 is rotatably connected to the lead screw 2 through the bearing installed in its inner cavity, and the Z-axis motor housing 3 is rotatably connected to the lead screw 2 through the bearing installed in the lower part of its inner cavity. A bearing cover for shielding the bearing is installed at the end of the Z-axis motor housing 3 away from the motor plate 4.

[0031] The addition of coupling 32 and mandrel 33 allows the gauge base 5 to be fixed on coupling 32 for accuracy measurement even if the internal space of Z-axis motor base 3 is insufficient to install gauge base 5, thus solving the problem of insufficient internal space for gauge base 5 installation.

[0032] like Figures 1 to 2 As shown in the figure, in this embodiment, a Z-axis anti-collision rubber 11 is fixed at one end of the Z-axis bearing seat 1 near the lead screw 2, and a notch is opened on the peripheral surface of the Z-axis anti-collision rubber 11.

[0033] like Figure 1 and Figure 3 As shown in the figure, in this embodiment, the bearing cap is fixed with a Z-axis anti-collision adhesive 31 on one end face away from the Z-axis motor seat 3, and a circular hole for the lead screw 2 to pass through is provided at the center of the Z-axis anti-collision adhesive 31.

[0034] The Z-axis anti-collision rubber 2 31 installed at the bottom of the bearing cap and the Z-axis anti-collision rubber 11 installed at the top of the Z-axis bearing seat 1 are both installed on the moving area of ​​the lead screw 2, which plays a protective role and prevents damage caused by collision between objects.

[0036] like Figures 1 to 3 As shown in the figure, in this embodiment, the lead screw 2, coupling 32 and mandrel 33 are in a coaxial state. The coaxial state of the lead screw 2, coupling 32 and mandrel 33 is also equivalent to the dial indicator base 5 being directly installed on the top of the lead screw 2, which ensures the accuracy of the dial indicator.

[0037] In use, the base 5 is installed on the mandrel 33, and the mandrel 33 and the lead screw 2 are linked together by the coupling 32 to drive the dial indicator 6 to rotate, so that the measuring end of the dial indicator 6 rotates around the upper surface of the motor plate 4 once, and the flatness of the upper surface of the motor plate 4 is detected by the dial indicator 6.

[0038] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.
