Description

Technical Field

[0001] The utility model relates to the technical field related to rubber piece processing, in particular to a positioning tool for cutting automobile sealing pieces. Background Art

[0002] Rubber ring is an important rubber product, widely used in various fields, and in automobiles, it is mainly used in engines, gearboxes, fuel systems and cooling systems. Rubber sealing rings can provide effective sealing effects to prevent leakage of liquids or gases and ensure the normal operation of vehicles. In the processing of rubber sealing rings, after the rubber is demolded in the mold, some scraps will be produced on the outside of the rubber ring when the rubber ring is formed in the mold, so it needs to be cut and trimmed after the rubber ring is formed.

[0003] A Chinese patent with publication number CN213860287U discloses a rubber ring trimming device, including a work surface, a drive motor, a linkage mechanism, a sleeve and a nozzle, wherein a drive motor is installed on the upper left side of the work surface, and a turntable is fixed to the output end of the drive motor, a fixed plate is tightly fitted on the right side of the turntable, and a sleeve is integrally provided on the outer side of the fixed plate, a connecting plate is tightly fitted on the right side of the fixed plate, and a mounting bolt is penetrated and connected inside the connecting plate, one end of a spring is welded inside the sleeve, and a limiting block is fixed to the other end of the spring, and a material discharge chute is opened inside the work surface.

[0004] To summarize, the above patent installs the rubber ring through a sleeve, and drives the limit block to resist the rubber ring through a spring, so as to achieve a limiting effect on the rubber ring. However, since the diameter of the sleeve is inevitably larger than the diameter of the rubber ring, this method of fixing the rubber ring requires the rubber ring to be stretched with force when being sleeved on the sleeve, and since the limit block will extend outward under the action of the spring, it is necessary to press the limit block when sleeved to prevent it from popping out, which makes the installation and positioning of the rubber ring more troublesome. Utility Model Content

[0005] The purpose of the utility model is to provide a positioning tool for cutting automobile seals, so as to solve the problem that the diameter of the sleeve in the above patent proposed in the above background technology is necessarily larger than the diameter of the rubber ring. When the rubber ring is sleeved on the sleeve, it is necessary to stretch the rubber ring with force to make it sleeved on the sleeve, and because the limit block will extend outward under the action of the spring, it is necessary to press the limit block when sleeved to prevent it from popping out, which makes the installation and positioning of the rubber ring more troublesome.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a positioning tool for cutting automobile seals, comprising a base,

[0007] The top of the base is respectively fixed with an L-shaped fixing frame and a vertical plate, and a limiting column is arranged through the vertical plate, a connecting plate is arranged above the limiting column, and a cutter is fixed at the bottom of the connecting plate;

[0010] The vertical plate is provided with a driving mechanism 1, and the driving mechanism 1 is used to drive the cone to move horizontally;

[0011] The vertical plate is also provided with a second driving mechanism, and the second driving mechanism is used to drive the limiting column to rotate.

[0012] In the above technical solution, by reserving a certain tensioning space on the limiting column, the rubber ring can be installed and positioned more conveniently, thereby improving the working efficiency.

[0013] Preferably, the adjustment mechanism includes a motor 1, which is fixed to the top of the L-shaped fixing frame, and the output end of the motor 1 is connected to the screw rod, the screw rod is installed below the top of the L-shaped fixing frame, and a guide rod is also fixed below the top of the L-shaped fixing frame, the screw rod and the guide rod respectively pass through the connecting plate, and the screw rod and the connecting plate are threadedly connected.

[0014] In the above technical solution, the motor drives the screw rod to rotate, so that the screw rod can drive the connecting plate threadedly connected to it to move vertically, so that the distance between the tool and the limit column can be adjusted to facilitate cutting and trimming of rubber rings of different thicknesses. The guide rod can guide the vertical movement of the connecting plate.

[0015] Preferably, the driving mechanism comprises a cylinder, which is arranged on a vertical plate, and a movable plate is fixed to the output end of the cylinder, the movable plate is rotatably connected to the cone, and a slider is fixed to the side of the cone, and the slider is provided in multiple groups, and a sliding groove matching the slider is opened on the side of the limit column.

[0016] In the above technical solution, the cylinder can drive the movable plate to move laterally toward the side close to the vertical plate. When the movable plate moves laterally, it will drive the cone to move laterally inside the limit column. The slider and the slide groove can drive the cone to rotate with the limit column when the limit column rotates.

[0017] Preferably, the inner diameter of the notch is larger than its outer diameter, the arc block is the same size as the notch, a spring is sleeved on the movable rod, and both ends of the spring are respectively connected to the arc block and the well-shaped fixing frame.

[0018] In the above technical solution, since the inner diameter of the notch is larger than its outer diameter, and since the arc block is the same size as the notch, when the arc block is inserted into the notch, the arc block will not be displaced too much to cause the outer surface of the limit column to be uneven, thereby ensuring the flatness of the outer surface of the limit column.

[0019] Preferably, the second driving mechanism includes a second motor, which is installed on one side of the vertical plate, and a pulley is installed on the other side of the vertical plate, the pulley is connected to the output end of the second motor, the limiting column is provided with a pulley, and the pulley is connected to the pulley through a belt.

[0020] In the above technical solution, the motor 2 drives the pulley 1 to rotate, so that the pulley 1 can drive the pulley 2 and the limiting column to rotate through the belt, and then drive the rubber ring to rotate during trimming. Since a slider is provided on the cone and a slide groove is provided on the limiting column, when the limiting column rotates, the cone will be driven to rotate at the same time, and one end of the cone will also rotate on the movable plate.

[0021] Preferably, a collection box is provided below the limiting column.

[0022] In the above technical solution, the cut rubber waste can be collected through the collection box.

[0023] Compared with the prior art, the utility model has the following beneficial effects: the positioning tool for cutting automobile seals is

[0024] When in use, under the elastic force of the spring, the arc block, the movable rod and the wedge block will move toward one end close to the central axis of the limiting column, so that the outer surface of the limiting column is non-circular. In this way, when the rubber ring is installed, a certain tensioning space will be left, and there is no need to stretch the rubber ring. After the rubber ring is installed, the cone can be driven by the driving mechanism to move laterally, so that the cone drives the arc block to fit into the notch, thereby making the outer surface of the limiting column circular, thereby achieving the squeezing and fixing of the inner wall of the rubber ring, which can make the rubber ring more convenient to install and position, thereby improving the working efficiency.

[0025] The distance between the tool and the limit column can be adjusted by the adjustment mechanism, so that the position of the tool can be adjusted according to the rubber rings of different thicknesses, making it more widely used. In the process of cutting and trimming, the collection box can also collect the rubber waste dropped after trimming, thereby improving its functionality. BRIEF DESCRIPTION OF THE DRAWINGS
