Description
Technical Field
[0001] The utility model relates to the technical field of clamps, in particular to a tooling which is convenient for replacing a clamp plate. Background Art
[0002] The function of the steering gear is to appropriately transform the steering torque and steering angle from the steering wheel (mainly deceleration and torque increase), and then output it to the steering rod mechanism to make the car turn, so the steering gear is essentially a deceleration transmission device. When processing the steering gear housing, it needs to be fixed on the fixture plate, and different shapes of steering gear housings require different fixture plates. Since the steering gear usually needs to be rotated and moved during processing, the fixture plates are placed on the base plate tooling for joint use. Therefore, if each fixture plate is fixed on the base plate tooling, it will cause high production costs and will inevitably cause waste. Utility Model Content

DETAILED DESCRIPTION
[0023] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.
[0024] Embodiment, a tool for facilitating replacement of a fixture plate, such as Figure 1-2As shown, it includes a bottom plate 1, and the bottom plate 1 has symmetrical positioning components on both sides. The positioning components include two positioning plates 2 located at both ends of the bottom plate 1 on the same side. The two positioning plates 2 are L-shaped and slidably connected to the bottom plate 1. A clamping component is also provided in the middle of the bottom plate 1 between the positioning components on both sides. The clamping component includes two abutment blocks 3 arranged in a mirror image. The two abutment blocks 3 are slidably connected to the bottom plate 1 away from or close to each other. The sliding direction of the abutment blocks 3 is perpendicular to the sliding direction of the positioning plates 2. The sides away from the two abutment blocks 3 are slidably connected with a clamping plate 4. The clamping plate 4 is in a right-angle trapezoid. The oblique side plates of the two clamping plates 4 are away from each other in a direction away from the bottom plate 1. The top plate of the clamping plate 4 is vertically fixed. A vertical rod 6 is fixedly provided to penetrate the support plate 5, and the support plate 5 is parallel to the upper bottom plate 1 of the clamping plate 4 and is vertically fixed to the abutment block 3. A spring 7 is provided on the outer sleeve of the vertical rod 6 between the support plate 5 and the clamping plate 4, and the spring 7 drives the clamping plate 4 away from the support plate 5. A connecting rod 8 is hinged on both sides of each of the abutment blocks 3, and the other ends of the two connecting rods 8 on the same side are hinged on both sides of a sliding block 9. The two sliding blocks 9 are slidably connected to the two ends of a double-headed screw rod 10 and a slide groove 11. The two positioning plates 2 located on the same side of the bottom plate 1 are slidably connected to the double-headed screw rod 2 12 and the slide groove 2 13. The ends of the two double-headed screw rods 2 12 on both sides are coaxially fixed with a driving synchronous pulley 14 and a driven synchronous pulley 15, respectively. The driving synchronous belt The wheel 14 and the driven synchronous pulley 15 are sleeved with a synchronous belt, and the double-headed screw rod 10 is coaxially fixed with a hand crank 16. The active synchronous pulley 14 is coaxially fixedly connected with the hand crank 2 17. When the fixture plate needs to be installed on the base plate 1, the two fixture plates are first pressed tightly along the flush end edges of the two positioning plates 2, and then the hand crank 2 17 is rotated to drive the active synchronous pulley 14 and the driven synchronous pulley 15 to rotate, so that the two double-headed screw rods 2 12 are rotated, and finally the two positioning plates 2 on the same side are driven to approach each other, so that the two positioning plates 2 on both sides finally clamp the two fixture plates to a limit position, and then the hand crank 16 is rotated again to drive the two sliders on the double-headed screw rod 10 to approach each other, so that the two connecting rods hinged on each abutment block 3 The angle between the two abutment blocks 3 becomes smaller, driving the two abutment blocks 3 away from each other and pushing the clamping plate 4 close to the side of the clamping plate. When the clamping plate 4 begins to fit against the clamping plate 4, since the clamping plate 4 is a right-angled trapezoid and its hypotenuse is away from each other in the direction away from the bottom plate 1, the lower bottom plate 1 of the clamping plate 4 is finally pressed on the upper end surface of the clamping plate. At the same time, the outer side surfaces of the two abutment plates that are away from each other abut against the side of the clamp plate. Each clamp plate is tightly limited and clamped by the two positioning plates 2, the abutment plate and the clamping plate 4 at the same time, which improves the stability of the subsequent clamp plate when fixing the steering gear housing. At the same time, when different clamp plates need to be replaced, disassembly and installation are relatively simple and the operation efficiency is high. The tooling can be used in conjunction with clamp plates of different sizes, which greatly saves costs.
[0025] like Figure 1-2 As shown, a flexible layer is provided on the inner side of the positioning plate 2, and a flexible layer is provided on the bottom surface of the lower base plate 1 of the pressing plate 4, which reduces the wear on the fixture plate and improves the stability of the fixture plate.
[0026] like Figure 1-2 As shown, the connection between the bevel plate of the clamping plate 4 and the lower bottom plate 1 is set as an arc surface, which is convenient for the clamping plate 4 to fall onto the end surface of the clamping plate and also reduces the wear on the clamping plate.
[0027] like Figure 1-2 As shown, an anti-slip block 18 is provided on the vertical rod 6 to prevent the vertical rod 6 from slipping off the support plate 5.
[0028] Working principle of a tooling for facilitating the replacement of fixture plates:
[0029] When the clamp plate needs to be installed on the base plate 1, first, the two clamp plates are respectively pressed together along the flush end edges of the two positioning plates 2, and then the hand crank 17 is turned to drive the active synchronous pulley 14 and the driven synchronous pulley 15 to rotate, so that the two double-headed screw rods 12 are rotated, and finally the two positioning plates 2 on the same side are driven to approach each other, so that the two positioning plates 2 on both sides finally clamp the two clamp plates to a limited position, and then the hand crank 16 is turned again to drive the two sliders on the double-headed screw rod 10 to approach each other, so that the angle between the two connecting rods 8 hinged on each abutment block 3 becomes smaller, driving the two abutment blocks 3 away from each other, pushing the clamping plate 4 close to the clamp The side of the fixture plate, when the clamping plate 4 begins to fit against the clamping plate 4, since the clamping plate 4 is a right-angled trapezoid and its oblique sides are away from each other in the direction away from the bottom plate 1, the lower bottom plate 1 of the clamping plate 4 is finally pressed on the upper end surface of the fixture plate, and at the same time, the outer side surfaces of the two abutment plates that are away from each other abut against the side edges of the fixture plate, and each fixture plate is tightly limited and clamped by the two positioning plates 2, the abutment plates and the clamping plate 4 at the same time, which improves the stability of the subsequent fixture plate when fixing the steering gear housing. At the same time, when different fixture plates need to be replaced, disassembly and installation are relatively simple, and the operation efficiency is high. The tooling can be used in conjunction with fixture plates of different sizes, which greatly saves costs.
