Description

Technical Field

[0001] This utility model relates to the field of hole reamer technology, and more specifically to a hole reamer for machining mechanical parts. Background Technology

[0002] In the machinery manufacturing industry, hole enlargement of metal sheets is a common processing procedure. It is usually used to increase the diameter of existing holes to meet design requirements or assembly needs. The traditional method of hole enlargement is to enlarge holes by manual filing, which is inefficient and cannot be used for large-scale processing of metal sheets. Therefore, in order to improve the efficiency and accuracy of hole enlargement, many factories usually use mechanical hole enlargers to enlarge holes by drilling, thereby improving the hole enlargement efficiency of mechanical parts.

[0003] While reaming is a highly efficient method, the high-speed rotating drill bit continuously drills into the metal sheet during the reaming process. This causes continuous vibration in the metal sheet during the reaming process, which can easily lead to a decrease in machining accuracy and also cause significant wear on the drill bit. Utility Model Content

[0004] The purpose of this invention is to provide a hole-reaming machine for machining mechanical parts, which solves the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hole reamer for machining mechanical parts, comprising;

[0006] Base;

[0007] A bracket symmetrically arranged on the base and slidingly fitted;

[0008] A pressure block that is slidably mounted at the bottom of the bracket;

[0009] The fixing blocks are arranged in a linear array at the top of the base, and the fixing blocks are arranged coaxially with the pressure block.

[0010] A fixing component, comprising at least a limiting block symmetrically disposed on the sidewall of the fixing block and driven by the pressure block.

[0011] Preferably, a hydraulic rod is fixedly installed at the top of the base, a bracket is fixedly connected to the telescopic end of the hydraulic rod, a groove is provided at the bottom of the bracket, a first spring is fixedly installed in the groove, and a pressure block is fixedly connected to the first spring.

[0012] Preferably, a drill bit is fixedly installed on the telescopic end of the hydraulic rod.

[0013] Preferably, a metal plate is movably mounted on the base, and the metal plate is arranged coaxially with the drill bit.

[0014] Preferably, the top of the fixing block is provided with a sliding groove, a second spring is fixedly installed in the sliding groove, and a slider is fixedly installed on the end face of the second spring.

[0015] Preferably, the driven part of the slider abuts against the limiting block, and the sidewall of the limiting block abuts against the metal plate.

[0016] In the above technical solution, the hole-reaming machine for machining mechanical parts provided by this utility model has the following beneficial effects:

[0017] (1) By setting a base, a bracket, a pressure block, a fixing block and a limiting block, this utility model can easily reduce the vibration generated when the metal plate is enlarged. When the metal plate is placed on the base, the bracket installed on the base is driven to slide down, so that the bracket drives the pressure block to move down to press the metal plate. In the process of the pressure block moving down, the limiting block installed in the fixing block is driven to resist the metal plate, so that the metal plate is fixed more stably. This not only improves the fixing effect of the metal plate, but also reduces the vibration generated when the metal plate is enlarged, and improves the accuracy of the enlargement.

[0018] (2) By setting up a hydraulic rod, a groove and a first spring, this utility model can improve the pressing effect of the pressure block on the metal plate.

[0019] (3) By setting a drill bit, this utility model can drill holes while the pressure block fixes the metal plate.

[0020] (4) By setting a sliding groove, a second spring and a slider, this utility model can facilitate the pressure block to push the limiting block to fix the metal plate. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-2 As shown, a reaming machine for machining mechanical parts includes:

[0028] Base 1;

[0029] The brackets 3 are symmetrically arranged on the base 1 and slide together;

[0030] The pressure block 6 is slidably set at the bottom end of the bracket 3;

[0031] The fixing blocks 8 are arranged in a linear array at the top of the base 1, and the fixing blocks 8 and the pressure blocks 6 are arranged on the same axis.

[0032] The fixing component includes at least a limiting block 12 symmetrically disposed on the side wall of the fixing block 8 and driven by the pressure block 6.

[0033] Specifically, when the metal plate 7 needs to be enlarged, the metal plate 7 is placed on the base 1 and the bracket 3 is driven to move downward. During the downward movement of the bracket 3, the pressure block 6 is driven to press and fix the metal plate 7 onto the base 1, thereby fixing the metal plate 7 onto the base 1. Furthermore, during the downward pressing process, the pressure block 6 drives the limiting block 12 installed in the fixing block 8 to slide, so that multiple limiting blocks 12 simultaneously abut against the side wall of the metal plate 7, thereby fixing the metal plate 7 more stably.

[0034] In the above embodiment, by setting the base 1, bracket 3, pressure block 6, fixing block 8, and limiting block 12, the vibration generated during the enlargement of the metal plate 7 can be easily reduced. When the metal plate 7 is placed on the base 1, the bracket 3 installed on the base 1 is driven to slide down, causing the bracket 3 to drive the pressure block 6 to move down and press the metal plate 7. During the downward movement of the pressure block 6, the limiting block 12 installed in the fixing block 8 is driven to abut against the metal plate 7, thereby making the metal plate 7 more stable. This not only improves the fixing effect of the metal plate 7, but also reduces the vibration generated during the enlargement of the metal plate 7 and improves the accuracy of the enlargement.

[0035] As a further embodiment of this utility model, a hydraulic rod 2 is fixedly installed at the top of the base 1, a bracket 3 is fixedly connected to the telescopic end of the hydraulic rod 2, a groove 4 is provided at the bottom of the bracket 3, a first spring 5 is fixedly installed in the groove 4, and a pressure block 6 is fixedly connected to the first spring 5.

[0036] Specifically, the hydraulic rod 2 drives the bracket 3 to move downward, which in turn drives the pressure block 6 to move downward. When the pressure block 6 comes into contact with the end face of the metal plate 7, it slides into the groove 4 under pressure. This causes the first spring 5 in the groove 4 to be squeezed and continuously increase the thrust on the pressure block 6, thereby enabling the pressure block 6 to press and solidify the metal plate 7.

[0037] As another embodiment further provided in this utility model, a drill bit 13 is fixedly installed on the telescopic end of the hydraulic rod 2.

[0038] Furthermore, a metal plate 7 is movably mounted on the base 1, and the metal plate 7 is arranged coaxially with the drill bit 13.

[0039] Specifically, by installing the drill bit 13 at the bottom end of the hydraulic rod 2, the hydraulic rod 2 drives the pressure block 6 to press the metal plate 7 while simultaneously driving the drill bit 13 to move towards the metal plate 7 mounted on the base 1. This allows the drill bit 13 to directly enlarge the hole in the metal plate 7 after it has been pressed, thereby improving the hole enlargement efficiency of the metal plate 7.

[0040] As a further embodiment of this utility model, a groove 9 is provided at the top of the fixing block 8, a second spring 10 is fixedly installed in the groove 9, and a slider 11 is fixedly installed on the end face of the second spring 10.

[0041] Furthermore, the slider 11 is driven to abut against the limiting block 12, and the side wall of the limiting block 12 abuts against the metal plate 7.

[0042] Specifically, during the process of pressing and fixing the metal plate 7, the pressure block 6 pushes the slider 11 to slide into the fixing block 8, so that the slider 11 pushes the limiting block 12 to extend out of the fixing block 8 during the sliding process, thereby allowing the limiting block 12 to abut against the side wall of the metal plate 7, improving the fixing effect of the metal plate 7 and avoiding large vibrations of the metal plate 7 during the hole enlargement process. When the pressure block 6 disengages from the slider 11, the second spring 10 pushes the slider 11 to reset.

[0043] Working principle: When the metal plate 7 needs to be enlarged, the worker places the metal plate 7 on the base 1 and drives the support 3 to move down through the hydraulic rod 2. This causes the support 3 to push the pressure block 6 down onto the metal plate 7. When the pressure block 6 abuts against the end face of the metal plate 7, it slides into the groove 4 under pressure. This causes the first spring 5 to push the pressure block 6, thus enabling the pressure block 6 to press and fix the metal plate 7. At the same time, the hydraulic rod 2 pushes the drill bit 13 to move continuously towards the metal plate 7, allowing the drill bit 13 to enlarge the hole in the metal plate 7. The pressure block 6 also pushes the slider 11 to move into the groove 9, causing the slider 11 to push the limiting block 12 against the side wall of the metal plate 7, thereby increasing the fixing effect of the metal plate 7 and reducing the vibration generated by the metal plate 7 during drilling.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
