Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing equipment and relates to a gauge frame mechanism for a bearing inner hole grinder. Background Art

[0002] The gauge is a high-precision accessory for measuring the inner hole of the bearing, so the accuracy of the gauge frame will affect the measurement error. At present, the gauge frame mechanism of the bearing inner hole grinder adopts double linear bearings for left and right movement. Generally, the machine tool grinding frame has two movement directions, one is the oscillation (left and right) direction, and the other is the feed (front and back) direction. When grinding, the feed direction is also moving at the same time as the oscillation direction. The vibration of the feed movement is directly transmitted to the gauge frame, resulting in large dimensional dispersion and poor concentration of the inner hole processing. Therefore, the gauge frame mechanism of the bearing inner hole grinder is urgently needed. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , the utility model provides a technical solution: a gauge frame mechanism for a bearing inner hole grinder, including an oscillating transmission frame mechanism, which is used to transmit the oscillating motion of the machine tool grinding frame to the gauge;

[0022] The oscillating transmission frame mechanism includes a graphene copper sleeve 2, an oil seal 3, a push rod 4 and a fixing plate 5;

[0023] The graphene copper sleeve 2 is slidably connected to the push rod 4, the right side of the push rod 4 is fixedly connected to the fixed plate 5, the oil seal 3 is arranged on the right side of the graphene copper sleeve 2 and is slidably connected to the push rod 4, and the left side of the fixed plate 5 is provided with a cylinder 1;

[0024] Also included is a gauge stand 11 for mounting a gauge.

[0025] The graphene copper sleeve 2 has a self-lubricating effect, and the oil seal 3 has an anti-fouling property. By using the oil seal 3 in conjunction with the push rod 4, the fixing plate 5, and the graphene copper sleeve 2, the oscillating motion of the machine tool grinding frame can be transmitted to the measuring gauge, thereby ensuring the repeatability of the reciprocating motion of the measuring gauge.

[0026] A copper sleeve shell 13 is arranged outside the graphene copper sleeve 2, the push rod 4 is slidably connected to the copper sleeve shell 13, the upper side of the copper sleeve shell 13 is fixedly connected to the cylinder 1, a telescopic rod is connected to the right side of the cylinder 1, and the telescopic rod is fixedly connected to the fixing plate 5.

[0027] The telescopic rod is driven by the cylinder 1 to move freely to the right. When the cylinder 1 drives the telescopic rod to move to the right, the telescopic rod drives the fixed plate 5 to move to the right, and the fixed plate 5 drives the push rod 4 to move to the right, so as to facilitate the gauge in the gauge frame 11 to be away from the bearing.

[0028] The left side of the push rod 4 is sleeved with a tension spring 12 , the right end of the tension spring 12 is fixedly connected to the copper sleeve shell 13 , and the left end of the tension spring 12 is fixedly connected to the left side of the push rod 4 .

[0029] A guide rail frame 10 is disposed at the lower side of the copper sleeve housing 13 . The guide rail frame 10 is connected to the fixing plate 5 via a floating joint 6 . The lower side of the guide rail frame 10 is connected to a base 9 .

[0030] The base 9 is connected to the grinder using multiple locking bolts around the outer side. The base 9 is fixedly connected to the copper sleeve shell 13. The floating joint 6 is used to connect the push rod 4 and the guide frame 10 to adjust the axis of the gauge. When the fixed plate 5 and the guide frame 10 are fastened with screws in the prior art, the vibration of the machine tool grinding frame and the feed movement will be directly transmitted to the gauge frame 11, affecting the repeated measurement accuracy of the gauge in the gauge frame 11. By using the floating joint 6 instead of the connecting screws in the prior art, the floating joint 6 can eliminate the vibration of the machine tool grinding frame in the feed direction, and also rhythmically transmit the vibration movement of the machine tool grinding frame to the gauge, so that the processed bearing meets the use requirements. The base 9 has a supporting function.

[0032] The sliding connection between the linear guide rail 7 and the guide rail frame 10 facilitates adjustment of the position of the left and right sides of the guide rail frame 10; the oil-proof cover 8 has a protective function.

[0033] The linear guide rail 7 is a double linear guide rail with clearance.

[0034] When the utility model is in use, the measuring gauge is installed in the circular hole below the measuring gauge frame 11, and the push rod 4 is connected to the oscillating component of the grinder. When the inner hole of the bearing is ground in the grinder, the cylinder 1 drives the telescopic rod to move to the left, drives the push rod 4 to move to the left, and the push rod 4 is pressed tightly onto the oscillating grinding electric spindle under the action of the tension spring 12 to realize left and right movement measurement. When the size of the bearing is ground to the set value, the cylinder 1 drives the telescopic rod to move to the right, the telescopic rod drives the fixed plate 5 to move to the right, and the fixed plate 5 drives the push rod 4 to move to the right, so that the measuring gauge in the measuring gauge frame 11 is conveniently moved away from the bearing. When the measuring gauge leaves the measuring area, the grinding electric spindle stops grinding.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
