Description

Technical Field

[0001] This utility model relates to the field of hydraulic casting inspection and positioning technology, and in particular to a hydraulic casting processing inspection and positioning mechanism. Background Technology

[0002] Hydraulic castings refer to hydraulic system components produced through casting processes. They are typically used to withstand the transmission or control of high-pressure fluids. Common classifications of hydraulic castings include hydraulic valve bodies, hydraulic pump / motor housings, and auxiliary support components. Among these, bearing housings are used to mount bearings in hydraulic pumps, motors, or hydraulic cylinders, ensuring the rotational accuracy of the shaft system (e.g., bearing housings for gear pumps and end cap bearing housings for piston motors).

[0003] Existing bearing machining and inspection positioning mechanisms are placed with the bottom of the bearing housing as the reference plane. The two sides of the bearing housing are directly clamped by clamping parts that move in opposite directions or in one direction. For example, a bearing housing machining precision inspection device with publication number CN222211462U clamps and fixes the two sides of the bearing housing by two positioning plates that move in opposite directions and a detachable and replaceable clamping plate. This clamping method does not limit the degree of freedom of the bearing housing enough, which affects the machining stability of the bearing housing. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a hydraulic casting processing inspection and positioning mechanism, which is designed for clamping, positioning and position detection during bearing housing processing, meets the multi-degree-of-freedom constraints of bearing housings with different thicknesses and widths, improves the stability of bearing housing processing and positioning, and reduces visual inspection interference of bearing housings.

[0006] To achieve the above objectives, this utility model proposes a system comprising a base, a three-axis moving platform, two industrial cameras, two positioning components, and a drive device. The three-axis moving platform is mounted on the base, and the two industrial cameras are mounted on the mobile terminals of the three-axis moving platform. The positioning components include two support slides, two limiting mechanisms, and two adjusting mechanisms. The two support slides slide opposite each other on the base via the drive device. The two adjusting mechanisms are respectively mounted on their corresponding support slides, and the two limiting mechanisms are movably connected to the support slides via the adjusting mechanisms.

[0007] This utility model relates to a hydraulic casting machining and inspection positioning mechanism for clamping, positioning, and position detection during bearing housing machining. A drive device moves a support slide plate in opposite directions, while an adjustment mechanism moves a limiting mechanism up and down for adjustment. This accommodates bearing housings of varying thicknesses and widths. The opposing movement of the limiting and adjustment mechanisms increases the multi-degree-of-freedom constraints during bearing housing positioning. Combined with a three-axis moving platform that moves an industrial camera, the mechanism performs visual inspection of the parts, improving position detection at the bearing housing's shaft hole and edges.

[0008] In addition, the hydraulic casting machining and inspection positioning mechanism proposed above according to this utility model may also have the following additional technical features:

[0009] Specifically, the adjusting mechanism includes a cylinder, wherein,

[0010] The cylinder is mounted on the support slide plate, and the telescopic end of the cylinder passes through the support slide plate and is connected to the limiting mechanism.

[0011] Specifically, the limiting mechanism includes a support platform and a positioning rod, wherein,

[0012] The support platform is movably connected to the support slide plate via the telescopic end of the cylinder;

[0013] The positioning rod is located on the outside of the support slide plate.

[0014] Specifically, the positioning rod is inclined and forms a positioning groove with the support platform.

[0015] Specifically, the three-axis moving platform includes an X-axis moving mechanism, a Y-axis moving mechanism, and a Z-axis moving mechanism, wherein,

[0016] The Z-axis moving mechanism is mounted on the base;

[0017] The Y-axis moving mechanism is located at the drive end of the Z-axis moving mechanism;

[0018] The X-axis moving mechanism is located at the drive end of the Y-axis moving mechanism;

[0019] The two industrial cameras are mounted on the drive end of the X-axis moving mechanism.

[0020] Specifically, a limiting groove is provided on the base, and the supporting slide plate is limited to slide within the limiting groove.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0028] The 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 intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0029] The hydraulic casting processing, inspection, and positioning mechanism of this utility model embodiment will be described below with reference to the accompanying drawings.

[0030] like Figures 1-4 As shown, the hydraulic casting processing and inspection positioning mechanism of this utility model embodiment may include a base 1, a three-axis moving platform 2, two industrial cameras 3, two positioning components 4, and a drive device 5.

[0031] The three-axis moving platform 2 is mounted on the base 1, and the two industrial cameras 3 are mounted on the mobile terminal of the three-axis moving platform 2.

[0032] It should be noted that in the above embodiment, the base 1 supports the three-axis moving platform 2, the positioning component 4 and the driving device 5. The two positioning components 4 are adjusted to move towards each other by the driving device 5 to achieve the support and positioning of the bearing seat. The three-axis moving platform 2 drives the two industrial cameras 3 to move and adjust along the X, Y and Z directions of the bearing seat on the base 1, so that the two industrial cameras 3 can view the bearing seat from above and perform visual inspection on the edge shape and shaft hole position of the bearing seat.

[0033] The positioning component 4 includes two support slides 41, two limiting mechanisms 42, and two adjusting mechanisms 43.

[0034] Two support slide plates 41 slide opposite each other on the base 1 via a drive device 5, two adjustment mechanisms 43 are respectively set on the corresponding support slide plates 41, and two limit mechanisms 42 are movably connected to the support slide plates 41 via the adjustment mechanisms 43.

[0035] It should be noted that, in this embodiment, the two support slide plates 41 move towards each other against the upper surface of the base 1, and the sliding stability of the support slide plates 41 is increased by the limiting groove opened on the upper surface of the base 1. At the same time, the two limiting mechanisms 42 and the two adjusting mechanisms 43 move synchronously. The adjusting mechanism 43 drives the limiting mechanism 42 to move up and down above the support slide plate 41 to adjust and achieve the clamping and positioning of the bearing seat.

[0036] Specifically, when it is necessary to process, inspect and position the bearing housing, the bearing housing is placed on two positioning components 4. The two positioning components 4 are brought closer by the driving device 5, and the supporting slide plate 41 is attached to the upper surface of the base 1 to drive the limiting mechanism 42 and the adjusting mechanism 43 to slide synchronously. Then, the adjusting mechanism 43 supports the limiting mechanism 42 upward. The limiting mechanism 42 is used to fasten and position the two sides of the bearing housing, thereby realizing the multi-angle freedom restriction of the bearing housing.

[0037] In one embodiment of this utility model, such as Figure 2 As shown, the adjustment mechanism 43 includes a cylinder 431.

[0038] The cylinder 431 is mounted on the support slide plate 41, and the telescopic end of the cylinder 431 passes through the support slide plate 41 and is connected to the limiting mechanism 42.

[0039] It should be noted that the cylinder 431 described in this embodiment is located at the bottom of the support slide plate 41. The telescopic end of the cylinder 431 drives the limiting mechanism 42 to move up and down above the support slide plate 41 for adjustment, and the limiting rods that slide through the support slide plate 41 on both sides increase the stability of the support platform 421 moving up and down.

[0040] In one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4As shown, the limiting mechanism 42 includes a support platform 421 and a positioning rod 422.

[0041] The support platform 421 is movably connected to the support slide plate 41 through the telescopic end of the cylinder 431, and the positioning rod 422 is located on the outside of the support slide plate 41.

[0042] The positioning rod 422 is inclined and forms a positioning groove 423 between itself and the support platform 421.

[0043] It should be noted that the support platform 421 described in this embodiment is directly connected to the telescopic end of the cylinder 431 and is driven up and down by the cylinder 431. When the support platform 421 pushes the bearing seat up, the bearing seat is pressed into contact with the positioning rod 422, so that the bearing seat is clamped in the positioning groove 423.

[0044] In one embodiment of this utility model, such as Figures 1-4 As shown, the three-axis moving platform 2 includes an X-axis moving mechanism 21, a Y-axis moving mechanism 22, and a Z-axis moving mechanism 23.

[0045] The Z-axis moving mechanism 23 is mounted on the base 1, the Y-axis moving mechanism 22 is mounted on the drive end of the Z-axis moving mechanism 23, the X-axis moving mechanism 21 is mounted on the drive end of the Y-axis moving mechanism 22, and the two industrial cameras 3 are mounted on the drive end of the X-axis moving mechanism 21.

[0046] It should be noted that in the above embodiment, the Z-axis moving mechanism 23 drives the Y-axis moving mechanism 22, the X-axis moving mechanism 21 and the two industrial cameras 3 to adjust their height. The Y-axis moving mechanism 22 drives the X-axis moving mechanism 21 and the industrial cameras 3 to move back and forth for adjustment. The X-axis moving mechanism 21 drives the industrial cameras 3 to move left and right for adjustment, thereby realizing the moving visual detection of the two industrial cameras 3. Combined with the parallel dual industrial camera 3 structure in the same direction, the detection accuracy is improved, the systematic error caused by lens distortion or installation tilt of a single camera can be eliminated, and the effective field of view can be expanded.

[0047] In summary, the hydraulic casting machining and inspection positioning mechanism of this utility model, for clamping, positioning and position detection during bearing housing machining, meets the multi-degree-of-freedom constraints of bearing housings with different thicknesses and widths, improves the stability of bearing housing machining and positioning, and reduces visual inspection interference to bearing housings.
