Description

Technical Field

[0001] This application relates to the field of machining center technology, and in particular to a honeycomb hollow structure slide ram. Background Technology

[0002] With the rapid development of social production and science and technology, mechanical products are becoming increasingly precise and complex, and the demand is frequently changing. The required mechanical parts have high precision requirements, complex shapes, and small batch sizes.

[0003] The ram is the core component of the machine tool's motion mechanism. It is connected to the slide block via guide rails to form a linear motion mechanism, providing mounting support for the machine tool spindle system. It has guide rails that allow it to move vertically on the slide block.

[0004] When the ram is installed vertically, the overhang increases synchronously as the working stroke of the ram increases. Under the action of cutting force, this causes flexural deformation, resulting in tool angle and displacement errors. Compensation measures are needed to ensure machining accuracy, so improvements are required. Utility Model Content

[0005] To achieve the above objectives, this application proposes a honeycomb hollow structure ram. The upper end of the ram is recessed on both sides to form a first recessed area. The two first recessed areas are separated by a trapezoidal boss on the upper surface of the ram, and the two first recessed areas are symmetrical about the boss. The lower end of the ram is recessed on both sides to form a second recessed area. A first mounting groove is provided in the first recessed area, and a second mounting groove is provided in the second recessed area. The first mounting groove and the second mounting groove are used to install the slide rail. The bottom base surfaces of the two sets of first mounting grooves are coplanar, and the bottom base surfaces of the two sets of second mounting grooves are arranged face to face to form a lateral clamping of the ram. The plane containing the bottom base surface of the first mounting groove is perpendicular to the plane containing the bottom base surface of the second mounting groove.

[0006] In the above-mentioned technical means, a symmetrical first recessed area is set at the upper end of the ram and a second recessed area is set at the lower end. The recessed structure is used to reduce redundant materials and achieve weight reduction. At the same time, the layout of the first and second mounting grooves makes the load transmission path more reasonable after the slide rail is installed, avoiding stiffness loss caused by weight reduction due to the recess, and ensuring the overall stiffness of the ram on the basis of weight reduction.

[0007] Specifically, the length-to-width ratio of the slide block is 1:1, where the length of the slide block is the distance from the upper edge of the boss to the bottom surface of the lower end of the slide block, and the width of the slide block is the distance between the non-recessed areas on both sides of the slide block.

[0008] By limiting the length-to-width ratio of the ram to 1:1, this ratio ensures that the ram is subjected to symmetrical and uniform forces, maximizing the overall rigidity of the hollow ram under the premise of the same amount of material.

[0009] Specifically, the inner wall of the ram is provided with reinforcing ribs; the reinforcing ribs include cross-shaped and regular hexagonal reinforcing ribs.

[0010] Through the above technical solution, a cross-shaped and regular hexagonal reinforcing rib is set on the inner side wall of the ram. The cross-shaped structure can evenly distribute the load to the entire ram, while the regular hexagonal honeycomb structure itself has the characteristics of being lightweight and having high rigidity. The combination of the two reinforcing ribs maximizes the internal rigidity of the ram with the least amount of material, avoiding material redundancy or insufficient rigidity caused by a single reinforcing rib, and achieving a balance between lightweight and high rigidity of the ram.

[0011] Specifically, the inner wall of the ram also includes reinforcing plates, which are evenly spaced on the inner wall of the ram and connected to the reinforcing ribs.

[0012] Reinforcing plates are set at equal intervals on the inner sidewall of the slide block and connected to reinforcing ribs. The reinforcing plates and reinforcing ribs form a synergistic reinforcement structure. The equal-interval layout makes the stiffness distribution more uniform and avoids the problem of local stiffness weakness.

[0013] Specifically, the inner sidewalls of the slide at the first and second mounting slots extend toward the center of the slide, forming a first reinforcing zone and a second reinforcing zone, respectively.

[0014] The stiffness reinforcement is applied only to the critical stress-bearing area of ​​the slide rail installation, rather than thickening the entire slide block. This reduces the amount of material used in non-critical areas while ensuring the stiffness of the core stress-bearing area, achieving a balance between lightweight and high stiffness of the slide block.

[0015] Specifically, the sum of the cross-sectional areas of the first and second reinforced regions is greater than the sum of the areas of the first and second depressions.

[0016] The above technical solution ensures that the sum of the cross-sectional areas of the first and second reinforced regions is greater than the sum of the areas of the first and second recessed regions, thus ensuring that the stiffness reinforcement effect of the reinforced regions can cover the stiffness loss caused by the weight reduction of the recessed regions; and effectively increases the cross-sectional area of ​​the ram.

[0017] Specifically, the ram is also provided with connecting grooves for connecting the ram seat; the connecting grooves are respectively located close to the first recess and the second recess.

[0018] Specifically, the ram is made of gray cast iron.

[0019] Specifically, the circumferential height of the reinforcing plate is higher than the circumferential height of the reinforcing rib.

[0020] Specifically, a temperature sensor is installed on the side wall of the slide block to detect changes in the temperature of the guide rail.

[0021] Temperature sensors are installed on the sidewalls of the slide to detect changes in the guide rail temperature. This allows for real-time monitoring of the thermal deformation trend caused by the guide rail temperature, avoiding the need to excessively increase the slide material to counteract unknown thermal deformation.

[0022] The advantages of this application compared to existing technologies are as follows: Increasing the profile significantly enhances structural rigidity by increasing the moment of inertia of the cross section, optimizing material distribution, and shortening the force flow path; It efficiently enhances rigidity within a limited space while adapting to dynamic load requirements, achieving a balance between lightweight and high rigidity.

In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0027] Figure 1 This is a schematic diagram of a honeycomb hollow structure slide block according to an embodiment of this application, as shown below. Figure 1As shown, a honeycomb hollow structure slide block 1 has two downward recessed areas on the upper end of the slide block 1 to form first recessed areas 101. The two first recessed areas 101 are separated by a trapezoidal boss on the upper surface of the slide block 1, and the two first recessed areas 101 are symmetrical about the boss. The two sides of the lower end of the slide block 1 are recessed inward to form second recessed areas 103. A first mounting groove 102 is provided in the first recessed area 101, and a second mounting groove 104 is provided in the second recessed area 103. The first mounting groove 102 and the second mounting groove 104 are used to install slide rails 3. The bottom base surfaces of the two sets of first mounting grooves 102 are coplanar, and the bottom base surfaces of the two sets of second mounting grooves 104 are arranged face to face to form a lateral clamping of the slide block 1. The plane where the bottom base surface of the first mounting groove 102 is located is perpendicular to the plane where the bottom base surface of the second mounting groove 104 is located.

[0028] Preferably, the ram 1 is also provided with a connecting groove 105, configured to connect the ram seat 2; the connecting groove 105 is respectively located close to the first recess and the second recess.

[0029] In a further preferred embodiment, the length-to-width ratio of the slide block 1 is 1:1, wherein the length of the slide block 1 is the distance from the upper edge of the boss to the bottom surface of the lower end of the slide block 1, and the width of the slide block 1 is the distance between the non-recessed areas on both sides of the slide block 1. This ratio makes the slide block 1 symmetrical and uniform in terms of force, and maximizes the overall rigidity of the hollow slide block 1 under the premise of the same amount of material. Figure 2 This is a cross-sectional view of a honeycomb hollow structure slide block according to an embodiment of this application, as shown below. Figure 2 As shown, the inner sidewalls of the slide block 1 at the first mounting groove 102 and the second mounting groove 104 extend toward the center of the slide block 1 and form the first reinforcing domain 106 and the second reinforcing domain 107 respectively. Preferably, the sum of the cross-sectional areas of the first reinforcing domain 106 and the second reinforcing domain 107 is greater than the sum of the areas of the first depression and the second depression.

[0030] Figure 3 This is a schematic diagram of the internal structure of a honeycomb hollow structure slide block according to an embodiment of this application, as shown below. Figure 3 As shown, the inner wall of the slide block 1 is provided with reinforcing ribs 108; the reinforcing ribs 108 include cross-shaped and regular hexagonal reinforcing ribs 108; Preferably, the inner sidewall of the slide block 1 also includes reinforcing plates, which are evenly spaced on the inner sidewall of the slide block 1 and connected to the reinforcing ribs 108.

[0031] In a further preferred embodiment, the circumferential height of the reinforcing plate is 108 times higher than the circumferential height of the reinforcing rib.

[0032] Meanwhile, in an optional scheme, a temperature sensor is provided on the side wall of the slide block 1 to detect changes in the guide rail temperature. In this embodiment, the temperature sensor is linked to the cooling system (not shown in the figure) to monitor the guide rail temperature rise in real time. When ΔT > 5°C, the cooling system sprays water.

[0033] Figure 4 This is a force diagram of a honeycomb hollow structure slide block according to an embodiment of this application, as shown below. Figure 4 As shown, in this embodiment, when the slide rails 3 located at the upper end and both sides of the slide ram 1 are subjected to force, it is obvious that the distance L1 from the resultant force of the two slide rails 3 to the center of the slide ram 1 is less than the torque in the traditional square / rectangular slide ram 1 (as shown by L2 in the figure).

[0034] In the above method, the installation of slide 1, slide rail 3 and slide seat 2 must meet the safe assembly limit; the safe assembly limit is determined by the nominal dimensions and manufacturing tolerances of each component.

[0035] Specifically, considering that the slide block 1, slide rail 3 and slide block seat 2 all have deviations from their standard dimensions in actual processing, the minimum distance reserved between slide block seat 2 and slide block 1 for installing slide rail 3 should be greater than the sum of the maximum limit thickness of slide rail 3 and the processing tolerances of each mating surface during assembly design.

[0036] In a preferred embodiment, a temperature sensor is provided on the side wall of the slide block 1 to detect changes in the guide rail temperature. The temperature sensor is linked to control the cooling system, and the cooling system sprays when ΔT > 5°C.

In this way, this application also aims to cover such modifications and alterations if they fall within the scope of the claims and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered limiting in scope.
