Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining, and more specifically, to a burr removal and grinding mechanism for machining holes in hydraulic valve blocks. Background Technology
[0002] In the manufacturing process of hydraulic valve blocks, hole machining is a crucial step. The internal structure of a hydraulic valve block contains multiple precision channels used to control the flow path of hydraulic oil. However, during hole machining, burrs often form at the edges of the holes due to factors such as tool wear, improper cutting parameters, or material properties. These burrs not only affect the appearance quality of the hydraulic valve block, but more importantly, they can interfere with the smooth flow of hydraulic oil and may even lead to hydraulic system malfunctions. Therefore, grinding away the burrs after hole machining in hydraulic valve blocks is of paramount importance.
[0003] Traditional deburring methods rely heavily on manual operation, which is not only inefficient but also makes it difficult to guarantee the quality of the deburring. With the development of automation technology, some automated deburring equipment has begun to be used for deburring hydraulic valve block holes after machining. However, these devices are often complex in structure, expensive, and have poor adaptability to hydraulic valve block holes of different sizes and shapes. Furthermore, some equipment is prone to interference between the instrument inserted into the hydraulic valve block hole and the hole wall during the deburring process, leading to uneven deburring or damage to the hydraulic valve block. Utility Model Content
[0004] The purpose of this invention is to provide a burr removal and grinding mechanism for hydraulic valve block holes, which solves the problem that existing grinding equipment is prone to interference with the hole wall during the grinding process, resulting in uneven grinding or even damage to the hydraulic valve block.
[0005] The embodiments of this utility model are achieved through the following technical solutions:
[0006] A burr removal and grinding mechanism for machining holes in a hydraulic valve block includes:
[0007] A grinder, comprising a grinding head and a rotating shaft;
[0008] A sleeve is provided with a through hole and several anti-interference components. The through hole is located inside the sleeve along its axial direction and extends through both ends of the sleeve. Several anti-interference components are arranged around the outer wall of the sleeve along its axial direction. Each anti-interference component includes two rotating seats, a sliding groove, a slider, an elastic element, two connecting rods, and a rolling ball. The sliding groove is located on the outer wall of the sleeve and is arranged along its axial direction. The slider is slidably disposed in the sliding groove. One end of the elastic element is connected to one end of the sliding groove, and the other end is connected to the slider. The two rotating seats are respectively located on the outer wall of the sleeve and on the slider. One end of each of the two connecting rods is hinged to the two rotating seats, and the other end is hinged to both sides of the rolling ball.
[0009] The grinding head is located at one end of the rotating shaft, and the other end of the rotating shaft is connected to the driving device, which drives the rotating shaft to rotate.
[0010] The two ends of the through hole are respectively provided with mounting grooves; the mounting grooves are provided with bearings and retaining rings; the bearings are located in the mounting grooves; the retaining rings are located on the outside of the bearings.
[0011] The rotating shaft passes sequentially through the inner rings of the bearings located at both ends of the through hole.
[0012] The slide groove is also provided with a limiting rod along its axial direction; the two ends of the limiting rod are respectively connected to the two ends of the slide groove; the slider is provided with a limiting hole, and the limiting rod passes through the limiting hole.
[0013] The elastic element is a spring, which is arranged around the limiting rod.
[0014] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:
[0015] 1. This utility model discloses a deburring and grinding mechanism for hydraulic valve block holes. Through a simple sleeve design and anti-interference components, this device ensures that during normal grinding operation, the rotating seat, connecting rod, and rolling ball work together. When the grinder rotates within the hole, the rolling ball flexibly conforms to the outer surface of the hydraulic valve block, effectively preventing interference with other parts of the hydraulic valve block. This not only ensures the uniformity of grinding but also prevents damage to the hydraulic valve block due to interference, thus guaranteeing the stability and safety of the grinding process.
[0016] 2. The present invention relates to a burr removal and grinding mechanism for machining holes in hydraulic valve blocks. Compared with some automated grinding equipment, this device has a simpler structure, reduces manufacturing costs, and is also easier to maintain and service.
[0017] 3. The present invention relates to a hydraulic valve block hole deburring and grinding mechanism. This device can also adapt to hydraulic valve block holes of different sizes. When the rolling ball contacts the hole wall, the slider in the anti-interference component slides simultaneously, so that the device can adapt to hydraulic valve block holes of different sizes and shapes. This design makes the device more widely applicable in practical applications and can meet the needs of different customers. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the 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.
[0025] like Figure 1 As shown, a burr-removing mechanism for machining holes in a hydraulic valve block includes a grinder and a sleeve 1. The grinder includes a grinding head 301, a rotating shaft 302, and a driving device. The grinding head 301 is located at one end of the rotating shaft 302, and the other end of the rotating shaft 302 is connected to the driving device, which drives the rotating shaft 302 to rotate, thereby driving the grinding head 301 to rotate for grinding burrs. The sleeve 1 is sleeved on the rotating shaft 302 of the grinder, allowing the rotating shaft 302 to rotate relative to the sleeve 1. It should be noted that the grinder is existing technology and is not an improvement in this embodiment, so it will not be described in detail here.
[0026] like Figure 1-4 As shown, the sleeve 1 is preferably triangular prism-shaped, and has a through hole 105 and 6 sets of anti-interference components. The through hole 105 is located inside the sleeve 1 along the axial direction of the sleeve 1 and extends through both ends of the sleeve 1. There are 3 chamfers at the corners of the outer wall of the sleeve 1. The anti-interference components are located at the chamfers of the outer wall of the sleeve 1.
[0027] Specifically, six sets of anti-interference components are arranged around three chamfers on the outer wall of sleeve 1, and two are arranged along the axial direction of sleeve 1;
[0028] More specifically, the anti-interference component includes two rotating seats 201, a sliding groove 101, a limiting rod 102, a slider 103, an elastic element, two connecting rods 202, and a rolling ball 203; the sliding groove 101 is located at the chamfer of the outer wall of the sleeve 1 and is arranged along its axial direction; the two ends of the limiting rod 102 are respectively connected to the two ends of the sliding groove 101; the slider 103 is provided with a limiting hole, through which the limiting rod 102 passes, so that the slider 103 can slide along the limiting rod 102; the elastic element is preferably a spring 104, which is arranged around the limiting rod 102, and its two ends are respectively connected to the sliding groove 101. One end of 01 is on the slider 103, so that after the slider 103 slides along the limiting rod 102, it can be reset under the action of the spring 104; two rotating seats 201 are respectively located at the chamfer of the outer wall of the sleeve 1 and the top of the slider 103; one end of the two connecting rods 202 is respectively hinged to the two rotating seats 201, and the other end is hinged to both sides of the rolling ball 203; when the slider 103 slides along the limiting rod 102, the distance between the two rotating seats 201 is increased or decreased, so that the rolling ball 203 moves closer or further away from the sleeve 1, thereby adapting to hydraulic valve block holes of different sizes;
[0029] More specifically, the connecting rod 202 has a rotating shaft 2021 and a rotating frame 2022 at both ends, and the rolling ball 203 has a mounting plane parallel to both sides; the rotating shaft 2021 is set perpendicular to the connecting rod 202 and is rotatably mounted on the rotating seat 201; the rotating frame 2022 is n-shaped, and its two ends are rotatably connected to the mounting planes on both sides of the rolling ball 203, so that the rolling ball 203 can rotate relative to the rotating frame 2022;
[0030] More specifically, mounting grooves are provided at both ends of the through hole 105; a bearing 106 and a retaining ring 107 are provided in the mounting groove; the bearing 106 is located in the mounting groove, its outer ring is in contact with the inner sidewall of the mounting groove, and its axis coincides with the axis of the through hole 105 on the sleeve 1; the retaining ring 107 is located on the outside of the bearing 106; the outer sidewall of the retaining ring 107 is also provided with threads; the inner sidewall of the mounting groove, except for the part in contact with the bearing 106, is also provided with threads; the retaining ring 107 is connected to the mounting groove by threads to restrict the axial movement of the bearing 106; the rotating shaft 302 passes through the inner rings of the bearing 106 located at both ends of the through hole 105 in sequence, so that the rotating shaft 302 can rotate more flexibly relative to the sleeve 1.
[0031] The working principle of this embodiment is as follows:
[0032] This utility model discloses a burr-removing and grinding mechanism for machining hydraulic valve block holes. During grinding, the sleeve 1 of this device is first fitted onto the rotating shaft 302 of the grinder. The rotating shaft 302 is then connected to the drive device. When the sleeve 1 and the grinder are simultaneously inserted into the hydraulic valve block hole, multiple rolling balls 203 contact the hole wall, causing the rolling balls 203 to move closer to or further away from the sleeve 1. Simultaneously, the slider 103 slides along the limiting rod 102, widening or narrowing the distance between the two rotating seats 201, thus adapting to hydraulic valve block holes of different sizes. The grinding head 301 of the grinder is then moved to the position to be processed, and the drive device is activated, causing the grinding head 301 to rotate. At this time, the position or angle of the grinder can be adjusted appropriately, ensuring the rolling balls 203 remain in contact with the hole wall. The sliders 103 around the sleeve 1 can move simultaneously. Under the action of the anti-interference component, the rotating shaft 302 of the grinder is protected by the sleeve 1, limiting its range of movement and thus avoiding interference with the hydraulic valve block body.
[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
