[0003] In the production of bearing outer rings, it is necessary to perform a quenching operation on the bearing outer ring, that is, use a quenching spray gun to rotate around the inner wall of the bearing outer ring to quench the inner wall of the bearing outer ring. The existing quenching operation requires quenching the bearing outer rings one by one. However, in order to improve the processing progress, the bearing outer ring will be hoisted and sent to the quenching equipment. When the bearing outer ring is hoisted, it is easy to cause unstable conditions such as shaking during the movement. Utility Model Content
[0004] The utility model aims to solve the above-mentioned shortcomings in the prior art and proposes a hoisting fixture for quenching the outer ring raceway of a bearing.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions: design a hoisting fixture for bearing outer ring raceway quenching, including a strip-shaped support seat, the top of which is connected to a hanger that drives the support seat to rise and fall;

[0007] A plurality of elastic anti-slip strips which are arranged at intervals are arranged on the inner side of the abutment plate and the inner side of the clamping plate.
[0008] Preferably, the anti-slip strip is a high temperature resistant elastic rubber strip, and the anti-slip strip is arranged along the axial direction of the abutment plate, and the anti-slip strip is fixed to the abutment plate and the clamping plate by bolts.
[0009] Preferably, the middle portion of the top surface of the abutment plate is fixed to the support seat, so that the two ends of the abutment plate are symmetrically arranged.
[0010] Preferably, the hanger includes a lifting mechanism, the bottom of the lifting mechanism is connected to a connecting seat, the connecting seat is fixed on the top of the supporting seat, and the top of the lifting mechanism is installed on the fixing seat.

[0012] Preferably, at least one sleeve is provided in parallel on the side of the lifting mechanism, the side of the sleeve is connected to the fixing seat through a connecting frame, a guide shaft is built in the sleeve, and the bottom of the guide shaft is fixed on the supporting seat.
[0013] The design scheme proposed by the utility model has the following beneficial effects during application:
[0014] 1. The hoisting fixture for quenching the outer ring raceway of the bearing pushes the clamping plate to rotate toward the inner side of the abutment plate through the pushing mechanism, so that the outer ring of the bearing placed under the abutment plate is pressed against the inner side of the abutment plate. As the clamping plate pushes the outer ring of the bearing toward the abutment plate, the outer ring of the bearing squeezes the anti-slip strip, which in turn deforms the anti-slip strip and generates a reverse force on the outer ring of the bearing, thereby improving the fixing effect of the outer ring of the bearing in the abutment plate and reducing the shaking of the outer ring of the bearing in the abutment plate.
[0015] 2. The hoisting fixture for quenching the outer ring raceway of the bearing passes through a hanger. During quenching, the outer ring of the bearing can be controlled to be raised and lowered, so that the fixture can place the outer ring of the bearing on the quenching spray gun.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-Figure 4A lifting fixture for quenching the outer ring raceway of a bearing comprises a strip-shaped support seat 1, the top of the support seat 1 is connected to a hanger for driving the support seat 1 to rise and fall, wherein the hanger comprises a lifting mechanism 9, the bottom of the lifting mechanism 9 is connected to a connecting seat 8, the connecting seat 8 is fixed on the top of the support seat 1, and the top of the lifting mechanism 9 is installed on a fixed seat 10, and the lifting mechanism 9 can control the support seat 1 to rise and fall.
[0023] Furthermore, a mounting plate 11 is installed on the top of the fixing seat 10, and through holes are opened at the corners of the mounting plate 11. Bolts can be used to fix the mounting plate 11 to a movable frame used to transport the fixture to the quenching device to facilitate the installation of the fixture.
[0024] It needs to be further explained that at least one sleeve 13 is provided parallel to the side of the lifting mechanism 9, and the side of the sleeve 13 is connected to the fixed seat 10 through a connecting frame 12. A guide shaft 14 is built into the sleeve 13, and the bottom of the guide shaft 14 is fixed on the support seat 1. When the support seat 1 is lifted or lowered, it can provide guidance for the lifting of the support seat 1, making the lifting of the support seat 1 more stable.
[0025] like Figure 1 and Figure 2 As shown, an arc-shaped and concave downwardly arranged support plate 2 is provided at the bottom of the support seat 1, wherein the middle part of the top surface of the support plate 2 is fixed to the support seat 1, so that the two ends of the support plate 2 are symmetrically arranged, and slots 3 are provided at both ends of the support plate 2, and arc-shaped clamping plates 4 are provided below the two sides of the support plate 2, the clamping plates 4 are coaxially arranged with the support plate 2, and the top of the clamping plates 4 is rotatably installed in the slot 3, so that the clamping plates 4 can rotate at the two ends of the support plate 2, and a pushing mechanism 5 is provided on the outer side of the clamping plates 4, and both ends of the pushing mechanism 5 are rotatably installed in U-shaped seats 6, one of the U-shaped seats 6 is fixed on the support seat 1, and the other U-shaped seat 6 is fixed on the outer wall of the clamping plates 4, and the pushing mechanism 5 provides power for the rotation of the clamping plates 4.
[0026] A plurality of elastic anti-slip strips 7 are arranged at intervals on the inner side of the abutment plate 2 and the inner side of the clamping plate 4, wherein the anti-slip strips 7 are high temperature resistant elastic rubber strips, and the anti-slip strips 7 are arranged along the axial direction of the abutment plate 2, and the anti-slip strips 7 are fixed to the abutment plate 2 and the clamping plate 4 by bolts.
[0027] Specifically, when in use, take the outer ring of the bearing (such as Figure 4 The position indicated by the middle arrow A) extends from the bottom of the support plate 2 into the support plate 2, and then the pushing mechanism 5 pushes the clamping plate 4 downward, so that the clamping plate 4 rotates toward the inside of the support plate 2, so that the clamping plate 4 is close to the outer ring of the bearing during the rotation, and squeezes the outer ring of the bearing in the direction of the inside of the support plate 2, so as to clamp and fix the outer ring of the bearing, and finally send the outer ring of the bearing into the quenching device for quenching operation.
[0028] Among them, with the progress of extrusion, the anti-slip strip 7 is deformed by the pressure, and provides elastic force to the outer ring of the bearing, providing more extrusion effect for the outer ring of the bearing, thereby improving the clamping effect of the outer ring of the bearing; and when the anti-slip strip 7 is subjected to force, the anti-slip strip 7 will be twisted and deformed, that is, the outer side of the outer ring of the bearing can be embedded between adjacent anti-slip strips 7, thereby increasing the friction between the outer ring of the bearing and the abutment plate 2 and the clamping plate 4, thereby making the outer ring of the bearing more stable.
[0029] It should be noted that the pushing mechanism 5 and the lifting mechanism 9 are both one of an electric push rod, a cylinder, and a hydraulic cylinder.
