Description

Technical Field

[0001] The utility model relates to the technical field of bearing bush processing, in particular to a device for measuring the symmetry of oil leakage holes of bearing bushes. Background Art

[0002] The bearing is an essential part of every engine. It is used to be installed in the contact part between the sliding bearing and the journal. The shape of the bearing is a semi-cylindrical surface with a very smooth surface. The main function of the bearing is to bear the force applied by the journal, maintain the stability of the oil film, make the bearing work smoothly and reduce the friction loss of the bearing. Therefore, the material of the bearing is also required to have a small friction coefficient, sufficient fatigue strength, good running-in performance and good corrosion resistance. It is generally made of wear-resistant materials such as bronze and anti-friction alloy.

[0003] In order to ensure the lubrication of the bearing and the engine crankshaft, an oil leakage hole is usually set at the center of the bearing. Since the bearing is a relatively precise part, there are strict requirements on the processing accuracy of the bearing. At present, when measuring the symmetry of the oil leakage hole, it is mainly measured manually with a vernier caliper to measure the minimum value from the oil leakage hole to the left and right sides of the bearing, and then the symmetry value is obtained after subtraction. Since the hole is an arc edge and the measurement is performed manually, the measurement error is large and the measurement efficiency is slow. At the same time, since the measured value must be calculated before the symmetry value can be obtained, it is also easy to produce artificial calculation errors, which will further cause large measurement errors.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0051] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like used in the present invention to indicate the orientation or position relationship is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0052] See also Figures 1 to 4 It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the utility model, and the drawings only show the components related to the utility model rather than the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0053] The utility model provides a device for measuring the symmetry of oil leakage holes of bearing bushes. Figure 1 As shown, the measuring device includes a base 10, on which a guide column 11 extending in a vertical direction is provided, on which a measuring assembly 20 is provided, the measuring assembly 20 includes a first mounting block 21, the first mounting block 21 is connected to the guide column 11, a sliding hole 210 extending in a vertical direction is provided on the first mounting block 21, a sliding guide column 22 is provided in the sliding hole 210, a conical measuring head 201 is connected to the bottom of the sliding guide column 22, the central axis of the conical measuring head 201 is perpendicular to the central axis of the sliding guide column 22, and the conical measuring head 201 protrudes from the first mounting block 21, and the conical measuring head 201 can move up and down; a measuring gauge 30 is also connected to the guide column 11, the measuring gauge 30 is located above the measuring assembly 20, the measuring gauge 30 includes a dial 301 and a measuring pressure head 302 connected to the dial 301, and the end of the measuring pressure head 302 contacts the top surface of the sliding guide column 22.

[0054] When the bearing oil leakage hole symmetry measuring device of the utility model is used, Figure 4 As shown, the bearing 100 is placed flat on the base 10, the oil leakage hole 101 on the bearing 100 is aligned with the conical measuring head 201, and the bearing 100 is pushed so that the conical measuring head 201 is gradually inserted into the oil leakage hole 101 until the oil leakage hole 101 and the conical measuring head 201 are fully matched, that is, the circumference of the conical measuring head 201 is fully in contact with the oil leakage hole. Therefore, in this process, the bearing 100 will push the conical measuring head 201 to move upward, and the conical measuring head 201 pushes the sliding guide When the column 22 moves upward, the sliding guide column 22 will compress the measuring pressure head 302 of the measuring gauge 30, and the dial 301 will display the corresponding reading. At this time, adjust the dial to the "zero" scale; then turn the bearing 100 180° and repeat the above operation. When the conical measuring head 201 is fully matched with the oil leakage hole, that is, the conical measuring head 201 cannot be inserted into the oil leakage hole (when the bearing cannot be pushed), the reading displayed on the dial 301 is the symmetry value of the oil leakage hole of the bearing 100. Therefore, compared with the manual method of measuring the symmetry of the oil leakage hole of the bearing by a vernier caliper in the prior art, the measurement operation of the oil leakage hole symmetry measuring device of the bearing is simple, more convenient and quick, and can greatly improve the measurement efficiency and measurement accuracy.

[0055] Specifically, before use, the bearing oil leakage hole symmetry measuring device can adjust the height of the measuring component 20 relative to the base 10 according to the different models and specifications of the bearings being measured, so that when the bearing is placed on the base, the central axis of the oil leakage hole 101 on the bearing 100 is at the same height as the central axis of the conical measuring head 201.

[0056] Specifically, Figure 1 As shown, in actual use, a measuring bottom plate 12 can be provided on the base 10 as needed, and a conical groove 120 is provided on the measuring pressure plate 12 at a position corresponding to the conical measuring head 201. The provision of the conical groove 120 can prevent the conical measuring head 201 from being too low and colliding with the measuring bottom 12 and causing damage when the measuring assembly 20 is adjusted up and down.

[0057] Preferably, Figure 2As shown, in this embodiment, the sliding hole 210 includes a first hole section 2101 and a second hole section 2102, the diameter of the first hole section 2101 is larger than the diameter of the second hole section 2102, and a limiting surface 2103 is formed at the connection between the first hole section 2101 and the second hole section 2102 (that is, the sliding hole 210 is a countersunk hole). Correspondingly, a positioning flange 221 is provided at the top of the sliding guide column 22, and the bottom of the positioning flange 221 contacts the limiting surface 2103. A receiving groove 230 is provided at the bottom of the sliding hole 210, and the receiving groove 230 intersects with the sliding hole 210. A connecting block 23 is provided in the receiving groove 230, and the connecting block 23 is connected to the bottom of the sliding guide column 22 by bolts, and the conical measuring head 201 is arranged on the connecting block 23.

[0058] Preferably, Figure 2 As shown, in the present embodiment, a first clamping hole 211 is provided on the first mounting block 21, and a first opening groove 212 is provided on one side of the first clamping hole 211. The first opening groove 212 divides the first mounting block 21 into a first clamping block 21a and a second clamping block 21b. The first clamping block 21a and the second clamping block 21b are both provided with threaded holes, and a first locking screw (not shown in the figure) is connected to the threaded hole on the first clamping block 21a and the threaded hole on the second clamping block 21b. The first locking screw can be adjusted to enable the first clamping hole 211 to clamp the guide column 11. Through this structural design, when it is necessary to adjust the height of the measuring assembly 20, i.e., the conical measuring head 201, the first locking screw is loosened so that the first clamping hole 211 loosens the guide column 11, and then the measuring assembly 20 can be adjusted up and down along the guide column 11. When adjusted to a suitable position, the first locking screw is tightened again so that the first clamping block 21a and the second clamping block 21b are relatively close, and then the first clamping hole 211 is contracted to clamp the guide column 11 to achieve fixation. The structure is simple and the operation is convenient.

[0059] Further, in order to facilitate the screwing of the first locking screw, preferably, Figure 1 As shown, a first rotating handle 24 is also provided at one end of the first locking screw.

[0060] Preferably, Figure 1 and Figure 3As shown, in the present embodiment, the measuring meter 30 is fixed on the guide column 11 by a second mounting block 41, and a second clamping hole 410 is provided on the second mounting block 41, and a second opening groove 411 is provided on one side of the second clamping hole 410, and the second opening groove 411 divides the second mounting block 41 into a third clamping block 41a and a fourth clamping block 41b, and threaded holes are provided on the third clamping block 41a and the fourth clamping block 41b, and a second locking screw (not shown in the figure) is connected to the threaded hole on the third clamping block 41a and the threaded hole on the fourth clamping block 41b, and the second clamping hole 410 can be clamped to the guide column 11 by adjusting the second locking screw. Through this structural design, it is convenient to adjust the distance between the measuring meter 30 and the measuring component 20 as needed during use, and the adjustment principle is the same as the adjustment principle of the above-mentioned measuring component, so it will not be repeated here. Further, in order to facilitate the screwing of the second locking screw, it is preferred that, as Figure 1 As shown, a second rotating handle 42 is also provided at one end of the second locking screw.

[0061] In summary, the bearing oil leakage hole symmetry measuring device of the utility model is simple to operate, convenient and quick, and can measure the symmetry value of holes at any angle on the bearing, which can greatly improve the measurement efficiency and measurement accuracy. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
