Description

Technical Field

[0001] This utility model relates to a diamond grinding and polishing machine, and more particularly to a indexing double guide rail device for a diamond grinding and polishing machine. Background Technology

[0002] The indexing device is a key component in a diamond grinding and polishing machine. It is used to precisely position and rotate the diamond workpiece to be processed, ensuring that each crystal facet can be accurately ground and polished at a predetermined angle. Common indexing devices usually use a slide structure to realize the linear feed motion of the indexing fork and connect with the worm gear on the water drill chuck. The slide is usually guided and supported by a single slide rail.

[0003] For example, Chinese Patent No. CN201820459283.X discloses a face-changing transmission docking mechanism for a water-drilling and polishing machine. By movably mounting a sliding plate 5 on a frame 4, a slider 6 is connected to the bottom of the sliding plate 5. The slider 6 is connected to a slide rail 3 mounted on the frame 4 to guide the movement of the sliding plate. In this technical solution, the slide block is guided and supported by a single slide rail. However, in high-precision machining scenarios, many shortcomings are exposed. For example, the contact area between the slide block and the slide rail is limited, resulting in the motion load (including the weight of the fixture, dynamic inertial force, and grinding reaction force) being concentrated on a small contact surface. Under high-frequency reciprocating motion, the pressure per unit area increases significantly, accelerating the fatigue and wear of the contact surface between the slide rail and the slider. At the same time, relying on only a single slide rail for bearing and guiding, all friction and impact are applied to this single path. After long-term high-frequency use, scratches, pitting, or corrugated wear are prone to appear on the surface of the slide rail, leading to increased sliding resistance, poor movement, and even crawling. This not only affects the accuracy of motion, but also directly shortens the service life of the slide rail and slide block assembly.

[0004] Therefore, how to improve the stability of slider movement has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a indexing double guide rail device for a diamond grinding and polishing machine, which is equipped with double slide rails to increase the contact area of ​​the slider and thus improve the movement stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a frame, a slide rail on the frame, a sliding plate, and a slider on the sliding plate connected to the slide rail on the frame. The sliding plate moves along the slide rail by cooperating with the slide rail on the frame through the slider on it. The frame includes a mounting frame, and the slide rails are two pieces that are vertically parallel to each other and mounted on the mounting frame.

[0007] The present invention is further configured such that: each slider includes an upper mounting block and a lower mounting block for inserting the upper and lower sides of the middle of the slider; the upper mounting block and the lower mounting block are the same in shape and size and are symmetrically arranged; each slide rail is provided with an upper mounting slot corresponding to each upper mounting block.

[0008] The present invention is further configured such that each upper mounting block includes a bottom contact surface, and the area of ​​each contact surface is smaller than the opening area at the top of the upper mounting slot.

[0009] The present invention is further configured such that: each of the slide rails has a front limiting part and a rear limiting part on the front and rear sides of the corresponding mounting slot, the front limiting part and the rear limiting part have the same shape and size and are symmetrically arranged, the upper mounting block also includes a front contact surface, and the rear end face of each front limiting part abuts against the corresponding contact surface.

[0010] The present invention is further configured such that: the mounting frame also includes a baffle located on the front side, the mounting frame is made of waterproof material, and each slide rail is fixedly and detachably connected to the baffle.

[0011] The present invention is further configured such that the mounting frame is made of stainless steel.

[0012] The present invention is further configured such that: each of the slide rails is provided with a plurality of screw holes along the left-right direction, and the baffle is provided with a socket corresponding to each screw hole.

[0013] By adopting the above technical solution, the design of double slide rails forms a stable four-point or more-point support, effectively suppressing the pitch, sway, and tilt of the sliding plate during movement. This increases the contact area of ​​the sliding surface of the slider during sliding, providing a stable and durable motion foundation for subsequent high-frequency forward and backward movements. It reduces maintenance frequency and thus reduces wear on the slide rails caused by high-frequency movements. Furthermore, the load is shared by the two slide rails, reducing the load and wear per unit slide rail, extending the service life of the slider and guide rail, and consequently extending the service life of the slide rails.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-7 As shown, this utility model discloses a double-guide rail indexing device for a diamond grinding and polishing machine, including a frame (not shown in the figure), a slide rail 11 located on and fixed to the frame, a sliding plate 2, and a slider 21 located on the sliding plate 2 and connected to the slide rail 11 on the frame. The movement of the slider 21 is usually driven by a sliding drive component (such as a servo motor + ball screw, cylinder, etc., which is prior art, see CN202221385371.2). A clamping indexing device for a diamond grinding and polishing machine describes a sliding plate 2 that engages with a slide rail 11 on a frame via a slider 21, enabling movement along the slide rail 11. The frame includes a mounting frame 1, and two slide rails 11 are fixedly mounted on the mounting frame 1 in a vertically parallel configuration. The double slide rail design forms a stable four-point or more-point support, effectively suppressing the pitch, sway, and tilt of the sliding plate 2 during movement. This increases the contact area of ​​the sliding surface of the slider 21 during sliding, providing a stable and durable motion foundation for subsequent high-frequency forward and backward movements. It reduces maintenance frequency and thus reduces wear on the slide rail 11 from high-frequency movements. Furthermore, the load is shared by the two slide rails 11, reducing the load and wear per unit slide rail 11, extending the service life of the slider 21 and the guide rail, and consequently extending the service life of the slide rail 11.

[0019] In addition, it is worth noting that the entire indexing dual guide rail device in this technical solution is mounted on the side plate of the frame as a functional module, which can effectively utilize vertical space, freeing up space for the workbench or other components, and making it easier for operators to observe and approach the indexing and docking area.

[0020] By inserting the slider 21, which is fixed to the sliding plate 2, from the front side of the mounting frame 1 and then fixing it to the sliding plate 2 from the rear side by bolts or other means, the sliding drive can move the slider 21 to move the sliding plate 2.

[0021] Each slider 21 includes an upper mounting block 211 and a lower mounting block 212 for inserting the upper and lower sides of the middle of the slider 21. The upper mounting blocks 211 and the lower mounting blocks 212 are the same in shape and size and are symmetrically arranged. Each slide rail 11 is provided with an upper mounting slot 111 corresponding to each upper mounting block 211. Through the cooperation of the upper mounting blocks 211 and the corresponding upper mounting slots 111, the slider 21 located on the sliding plate 2 can be quickly and accurately aligned during installation after being installed on the frame, avoiding misalignment or tilting, improving assembly efficiency and consistency. At the same time, the presence of the upper mounting blocks 211 and the upper mounting slots 111 can provide guidance for the movement path of the slider 21 on the corresponding slide rail 11.

[0022] Each upper mounting block 211 includes a bottom contact surface 2111. The area of ​​each contact surface is smaller than the opening area at the top of the upper mounting slot 111. After the left or right end face of the slide rail 11 is aligned with the opening at one end of the mounting slot and inserted, the contact surface 2111 of each mounting block is smaller than the opening area at the top of the upper mounting slot 111. This makes it easier for the upper mounting block 211 of the slider 21 to align with the upper mounting slot 111 during the process of mate between the slider 21 and the slide rail 11. Similarly, the lower mounting block 212 can also enter the corresponding position more smoothly.

[0023] Each slide rail 11 has a front limiting part 112 and a rear limiting part 113 on the front and rear sides of the corresponding mounting slot, respectively. The front limiting part 112 and the rear limiting part 113 are the same in shape and size and are symmetrically arranged. The upper mounting block 211 also includes a front contact surface 2112. The rear end face of each front limiting part 112 abuts against the corresponding contact surface 2112. After the slider 21 is installed into the corresponding slide rail 11, the presence of the front limiting part 112 and the rear limiting part 113 on the front and rear sides of the slide rail 11 in the mounting slot means that the rearward movement of the front limiting block is restricted by the upper mounting block 211 and the lower mounting block 212 on the slide rail 11. Similarly, when the rear limiting part 113 moves forward, it is also restricted by the upper mounting block 211 and the lower mounting block 212 on the slide rail 11. Thus, without the action of external force, the cooperation stability between the slide rail 11 and the corresponding slider 21 is further improved.

[0024] In addition, the mounting frame 1 also includes a baffle 12 located on the front side. The mounting frame 1 is made of waterproof material. Each slide rail 11 is detachably connected to the baffle 12 by bolts or other means. Since each slide rail 11 is detachably connected to the baffle 12, after the slider 21 is engaged with the corresponding slide rail 11, the baffle 12 is fixed to the slide rail 11, preventing external moisture from directly entering the front of the mounting frame 1. The side is restricted by the side plate of the mounting frame 1, thus achieving waterproofing. Furthermore, the slide rail 11 can be separated from the baffle 12, which facilitates the slider 21 entering the mounting frame 1 and engaging with the slide rail 11.

[0025] Preferably, the mounting frame 1 is made of stainless steel. Since there is a chromium oxide passivation film on the surface of stainless steel, it can effectively isolate oxygen, water vapor and corrosive media (such as acids, alkalis and salts), preventing the internal metal from being further oxidized and corroded.

[0026] Each of the slide rails 11 has a number of screw holes 114 arranged in the left-right direction. The baffle 12 is provided with a socket 121 corresponding to each screw hole 114. The bolts that are compatible with each screw hole 114 are inserted into the socket 121 to complete the thread engagement with the corresponding screw hole 114, thereby fixing the slide rail 11 and the baffle 12. Rotating the bolts in the opposite direction can separate the baffle 12 from the mounting frame 1.

[0027] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
