Description

Technical Field

[0001] This utility model relates to a horizontal steel ball grinding machine, specifically to an installation structure of a movable seat on a fixed seat in a horizontal steel ball grinding machine. Background Technology

[0002] Horizontal steel ball grinding machines include a fixed base and a movable base that is slidably mounted on a slide rail (see Publication No. CN221185973U, a propulsion mechanism for the movable base in a horizontal grinding machine). Currently, the movable base is slidably mounted on the fixed base via guide rail assemblies located symmetrically on both sides below it, such as Publication No. CN214559996U, a balance box type double-moving gantry for a linear guide grinding machine and a linear guide grinding machine. This causes the center of gravity of the movable base to be much higher than the guide rail assembly, making the connection structure between the movable base and the fixed base susceptible to the influence of horizontal force, resulting in poor stability of the movable base and thus preventing the grinding accuracy from being improved. Utility Model Content

The purpose is to change the force relationship of the connection structure between the movable seat and the fixed seat, thereby improving the stability of the movable seat and the grinding accuracy of the steel balls.

[0015] The present invention will now be described in detail with reference to the accompanying drawings. Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. The directional terms such as left, center, right, top, and bottom in the embodiments of the present invention are only relative concepts or referenced to the normal use state of the product, and should not be considered restrictive.

[0016] An installation structure for a movable seat on a fixed seat in a horizontal steel ball grinding machine, such as... Figure 1As shown, the system includes a fixed base 1, a movable base 3 on the top surface of the fixed base 1, the movable base 3 having a horizontal bottom surface and top surface, and vertical left and right side surfaces and end surfaces. A guide rail assembly 4 is provided on the fixed base 1, and the movable base 3 is slidably mounted on the fixed base 1 via the guide rail assembly 4. A first drive mechanism for driving the movable base 3 is fixedly provided on the fixed base 1. A pressure plate 2 and a second drive mechanism for driving the pressure plate 2 to rotate are rotatably mounted on the movable base 3 (the first and second drive mechanisms are not shown in the figure; both the first and second drive mechanisms are prior art, and for specific structures, please refer to CN221185973U, "A Servo Motor and its Components, Drive Motor and its Components in the Propulsion Mechanism of a Movable Base in a Horizontal Grinding Machine"). A first support platform 11 and a second support platform 12 are fixedly provided on the top surface of the fixed base 1. The first support platform 11 and the second support platform 12 are both strip-shaped and located on both sides of the movable base 3, and the length direction of the first support platform 11 and the second support platform 12 are both... Along the moving direction of the movable seat 3, the top surface of the first support platform 11 is higher than the top surface of the second support platform 12 and corresponds to the middle of the movable seat 3. To improve the stability of the first support platform 11, the lower part of the first support platform 11 is a conical structure with a smaller top and a larger bottom. The top surface of the second support platform 12 corresponds to the bottom of the movable seat 3. The guide rail assembly 4 is fixedly installed on the top surface of the first support platform 11 and the top surface of the second support platform 12. To facilitate the fixed connection between the movable seat 3 and the guide rail assembly 4, a first connecting platform 31 and a second connecting platform 32 are fixedly connected to both sides of the movable seat 3 along its moving direction. The first connecting platform 31 and the second connecting platform 32 are both strip-shaped and are located directly above the first support platform 11 and the second support platform 12, respectively. The guide rail assembly 4 includes a slide rail 41 and a slide block 42 that slide against each other. The slide rail 41 is fixedly connected to the corresponding first support platform 11 and the second support platform 12, and the slide block 42 is fixedly connected to the corresponding first connecting platform 31 and the second connecting platform 32, thereby facilitating assembly and maintenance.

[0017] To improve the stability of the connection structure between the first connecting platform 31 and the movable seat 3, a connecting part 33 is integrally provided between the side of the first connecting platform 31 along its length and the side of the movable seat 3 along its axial direction. The top surface of the connecting part 33 is an inclined surface that slopes upward from the first connecting platform 31 to the movable seat 3. To avoid the connecting part 33 affecting the center of gravity of the movable seat 3, the first connecting platform 31 and the second connecting platform 32 as a whole, multiple first weight-reducing grooves 331 are distributed on the bottom surface of the connecting part 33. Adjacent first weight-reducing grooves 331 are separated by partitions 332, which can both ensure the structural strength of the connecting part 33 and reduce the impact of the connecting part 33 on the center of gravity height of the movable seat and its components as a whole. The bottom surface of the first connecting platform 31 is horizontally arranged and is located in the same plane as the axis of the pressing plate 2.

[0018] To improve the stability of the connection structure between the second connecting platform 32 and the movable seat 3, the side of the second connecting platform 32 along its length is integrally connected to the lower part of the side of the movable seat 3 along its axial direction, and the top surface of the second connecting platform 32 and the side of the movable seat 3 are integrally connected by a vertical reinforcing rib plate 34; the height of the slide rail 41 located below the second connecting platform 32 is lower than the height of the bottom surface of the movable seat 3.

[0019] In use, the first drive mechanism drives the movable seat 3 to move, thereby pressing the pressing plate 2 and the fixed plate (not shown in the figure, installed on the fixed seat and corresponding to the pressing plate 2) together. The steel ball is located between the pressing plate 2 and the fixed plate. After the second drive mechanism drives the pressing plate 2 to rotate, the pressing plate 2 cooperates with the fixed plate to grind the steel ball. When the fixed plate and the pressing plate 2 are working, the movable seat 3 is subjected to force. Since the force between the first support platform 11 and the first connecting platform 31 is mainly downward gravity, the connection structure between the first support platform 11 and the second connecting platform 32 has a large tolerance to the horizontal component force and is not easy to be displaced. At the same time, the tapered structure at the bottom of the first support platform 11 can further improve the tolerance of the connection structure to the horizontal component force. Combined with the supporting and limiting effect of the connection structure between the second support platform 12 and the second connecting platform 32, the movable seat 3 as a whole has higher shock resistance, thereby improving the grinding accuracy of the steel ball.
