Abstract
Description
Technical Field
[0001] This utility model relates to the field of machine tools, and in particular to a large machine tool tailstock moving device. Background Technology
[0002] In modern industrial production, the tailstock is a crucial component of machine tools, and the ease and safety of its movement and positioning are paramount. Currently, tailstock movement mechanisms primarily rely on center lifting and roller pushing. This method performs exceptionally well with small tailstocks due to its simple structure, quick operation, and the ability for a single person to easily complete the movement task.
[0003] However, existing moving devices have significant limitations for large tail carriages. Due to their large size and weight, simply lifting them from the center is insufficient to maintain overall balance. This causes the tail carriage to easily tilt to one side during movement, especially on steps, where it can easily get stuck, making movement difficult. Therefore, moving large tail carriages often requires the cooperation of two people: one to hold the carriage upright and the other to push it. In some cases, even heavy equipment such as overhead cranes are needed to complete the movement, which undoubtedly increases the complexity and danger of the operation. Utility Model Content

Detailed Implementation
[0031] The present invention will now be described in further detail. The embodiments described below are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0033] To address the problem of difficulty in moving large tailstocks with existing tailstock moving devices, this utility model provides a large machine tool tailstock moving device. The tailstock moving device 2 is fixedly installed in parallel on the tailstock support 1. The tailstock support 1 has several square holes 11 and is fixedly installed on the platform 3. The platform 3 has several sliding grooves 31. The square holes 11 and the sliding grooves 31 are interconnected.
[0034] Tail frame moving device 2 includes:
[0035] Pressure bar 21;
[0036] Two transmission components 22 are arranged in parallel on both sides of the pressure rod 21;
[0037] Each transmission component 22 includes:
[0038] Eccentric wheel 23 is fixedly connected in series with pressure rod 21;
[0039] The fixed base 24 is fixedly installed on the tailstock support base 1; the fixed base 24 has a connecting hole 241 through which the pressure rod 21 can pass; the fixed base 24 has a through hole 242 for the eccentric wheel 23 to be placed.
[0040] The bearing component 25 passes through the square hole 11 and is placed in the slide groove 31, and the bearing component 25 abuts against the eccentric wheel 23.
[0041] Specifically, depending on the actual needs, different sizes of eccentric wheels 23 can be selected and replaced to achieve different heights of lifting the tailstock support 1; at the same time, the starting point of pressing down can be adjusted by replacing eccentric wheels 23 with different eccentricities, thereby improving the convenience and adaptability of operation.
[0042] The preferred bearing component 25 of this utility model includes a bearing seat 251, a bearing column 252, and a bearing 253. The bearing 253 is fixed to the bearing seat 251 via the bearing column 252. The bearing 253 is in contact with the bottom of the slide groove 31. This achieves stable fixing and efficient load bearing of the bearing 253, ensuring the stability and accuracy of the tailstock support 1 during movement, thereby improving the stability and reliability of the tailstock moving device 2 of this utility model.
[0043] Furthermore, depending on actual needs, the load-bearing capacity of the tailstock moving device 2 of this utility model can be increased by replacing the bearing housing 251, bearing column 252, and bearing 253.
[0044] The preferred slide groove 31 of this utility model is a T-shaped groove, which, when used in conjunction with a T-shaped screw, effectively allows the tailstock support 1 to slide smoothly relative to the platform.
[0045] To enhance the stability and durability of the structure of this utility model, the pressure rod 21 preferably includes a long rod 211, a connecting rod 212, and a short rod 213; wherein the long rod 211 passes through two connecting holes 241.
[0046] The pressure bar 21 of this utility model is preferably in the shape of an I-beam. Compared with the original component with the same function, the I-beam shape improves the ease of use; and when the tailstock is too heavy, the I-beam pressure bar 21 of this utility model can be pressed down by stepping on it, thereby reducing the labor intensity.
[0047] In addition, depending on the specific actual needs, different platforms 3 can be adapted by replacing the pressure rods 21 of different lengths.
[0048] The present invention preferably has two tailstock moving devices 2, which are symmetrically installed on the tailstock support 1. This symmetrical layout provides better balance and stability, ensuring that the force can be evenly distributed when lifting the tailstock support 1, reducing the possibility of tilting or deflection, thereby achieving smooth lifting and sliding operations.
[0049] The preferred tailstock moving device 2 of this utility model also includes a plurality of fixing pins 26, and fixing pin holes 243 that match the fixing pins 26 are provided on the fixing base 24. After being pressed down to the fixed position, the position can be quickly and securely locked by the cooperation of the fixing pins 26 and the fixing pin holes 243, preventing the tailstock support 1 from falling back or shifting due to external force, thereby enhancing the safety and reliability of the tailstock moving device 2 of this utility model.
[0050] The present invention preferably has two fixing pins 26 on each fixing base 24; this makes the fixing more secure, reduces the risk caused by the failure of a single fixing pin hole 243, and at the same time, it makes it easier for the operator to fix from different angles, improving the convenience of installation and adjustment.
[0051] The steps of using this utility model are as follows: by pressing down the pressure rod 21, the eccentric wheel 22 presses down the bearing seat 251, and then the tail support seat 1 is lifted by the bearing and makes it slide smoothly with the platform 3.
[0052] First, the operator presses down the pressure rod 21, causing the eccentric wheel 22 to act downward on the bearing component 25, thereby lifting the tail support 1. With the support of the bearing 253, the tail support 1 can slide smoothly with the platform 3, ensuring the stability and safety of the large tail frame during movement.
[0053] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
