Description

Technical Field

[0001] This utility model relates to the field of bearing processing, specifically to a bearing grinding end face support drilling fixture. Background Technology

[0002] Currently, bearing grinding machines use a large number of end face supports, and the mounting holes connecting the end face supports to the machine tool flange come in several specifications, meaning the center distance between the end face support holes varies (the appropriate end face support is selected based on the machine tool type). For example... Figure 1 The center distance d between holes has standard sizes of φ30, φ60, and φ100. For φ30 holes, three holes are drilled; for φ60 and φ100 holes, four holes are drilled. Disadvantage: Previously, after the end face support was turned, drilling involved a fitter using a special instrument to mark lines on it, followed by drilling with a drilling machine. This process was time-consuming and wasteful of manpower and resources. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model proposes a bearing grinding end face support drilling fixture, which is ingeniously designed and has a reasonable and compact structure. It solves the problem of repeated scribing and positioning for drilling on different end faces, saves time, and ensures accurate positioning.

[0004] The technical solution of this utility model:

[0005] A bearing grinding end face support drilling fixture includes a main body designed in a disc shape. The upper center of the main body has a first locating groove, and the lower center has a second locating groove. The first and second locating grooves are coaxial. Several sets of locating holes are designed around the circumference of the main body from the outside in. Each locating hole axially penetrates the main body vertically, and each set of locating holes is distributed in a ring shape on the main body. The first locating groove has a depth of 8mm and an inner diameter of φ18mm; the second locating groove has a depth of 8mm and an inner diameter of φ25mm; and the locating holes have an inner diameter of φ9mm.

[0006] The aforementioned sets of positioning holes consist of four sets, which, from the inside out, are the first set of positioning holes, the second set of positioning holes, the third set of positioning holes, and the fourth set of positioning holes.

[0007] The first set of positioning holes is designed as three positioning holes, which are 15mm away from the axis. The diameter of the first set of positioning holes is φ7mm.

[0008] The second set of positioning holes is designed as four positioning holes, which are 30mm away from the axis. The diameter of the second set of positioning holes is φ9mm.

[0009] The third set of positioning holes is designed as four positioning holes, with the four positioning holes 37.5mm away from the axis center, and the diameter of the third set of positioning holes is φ9mm.

[0010] The fourth set of positioning holes is designed as four positioning holes, each 50mm from the axis center, and the diameter of the fourth set of positioning holes is φ9mm.

[0011] The axial thickness of the main body is 30mm, and the diameter of the main body is φ120mm.

[0012] The bearing grinding end face support drilling fixture also includes a positioning stop pin, the outer diameter of which is the same as the diameter of the hole to be drilled.

[0013] The advantages of this utility model are: by designing a disc-shaped tooling, the end face support to be drilled can be accurately fixed, and the subsequent drilling can be quickly positioned, which can meet the use of end face supports of various sizes, save drilling time, and ensure drilling accuracy.

[0016] Figure 3 This is a front view schematic diagram of this utility model. Detailed Implementation

[0017] See attached document Figure 2-3 This is a bearing grinding end face support drilling fixture, comprising a main body 1, designed in a disc shape. The upper center of the main body 1 has a first positioning groove 2, and the lower center of the main body 1 has a second positioning groove 3, both coaxially positioned. Several sets of positioning holes are designed around the circumference of the main body 1 from the outside in, each axially penetrating the main body 1 vertically. Each set of positioning holes is arranged in a ring shape on the main body 1. The first positioning groove 2 has a depth of 8mm and an inner diameter of φ18mm; the second positioning groove 3 has a depth of 8mm and an inner diameter of φ25mm; the positioning holes have an inner diameter of φ9mm. The depth and size of the positioning grooves match the end face support to be drilled, enabling rapid positioning for subsequent drilling and saving time.

[0018] The aforementioned group of positioning holes comprises four groups, from the inside out: the first group of positioning holes 4, the second group of positioning holes 5, the third group of positioning holes 6, and the fourth group of positioning holes 7. The first group of positioning holes 4 consists of three holes, each 15mm from the axis, with a diameter of φ7mm. The second group of positioning holes 5 consists of four holes, each 30mm from the axis, with a diameter of φ9mm. The third group of positioning holes 6 consists of four holes, each 37.5mm from the axis, with a diameter of φ9mm. The fourth group of positioning holes 7 consists of four holes, each 50mm from the axis, with a diameter of φ9mm. The distribution and number of these positioning holes are designed according to the specific end-face support model, facilitating quick and precise drilling. The axial thickness of the main body 1 is 30mm, and its diameter is φ120mm. The design is reasonably sized to meet the drilling requirements of end face supports of all models and sizes.

[0019] The bearing grinding end face support drilling fixture also includes a positioning stop pin 8, the outer diameter of which is the same as the diameter of the hole to be drilled. The positioning stop pin is designed to be inserted into the first end face support hole from the upper positioning hole after the first end face support hole is drilled, so as to effectively position it and prevent misalignment when drilling the remaining end face support holes, thus ensuring drilling accuracy.

[0020] In use, the end face support to be drilled is placed upside down on the worktable of the drilling machine and fixed with a vise or similar tool. The rear positioning boss of the end face support faces upward. The corresponding first or second positioning groove of this tooling is engaged with the positioning boss for positioning. Then, the drill bit passes through the corresponding set of positioning holes to drill the first end face support hole. The positioning stop pin is then inserted from the positioning hole of the main body into the first end face support hole for positioning, preventing the tooling from rotating and shifting, which would cause misalignment during drilling. Subsequent end face support holes can then be drilled in sequence. It is simple and convenient. If it is necessary to replace the end face support with a positioning boss of a different size, simply rotate this tooling 180 degrees for use.
