The utility model discloses the structure can be suitable for the grinding of different varieties stopper assemblies taut, and the commonality is strong, and convenient operation improves production efficiency, reduction in production cost.
Description
Technical Field
The utility model relates to a stopper processing technology field, concretely relates to a locking pull rod for stopper assembly cylindrical grinding for taut locking pull rod during stopper assembly cylindrical grinding.
Background
At present, a grinding mode (a positioning support shaft is arranged in a camshaft hole of a brake assembly to be machined in advance for auxiliary positioning) is adopted when the excircle of the brake assembly is machined, hooks at two ends of a locking pull rod are hung on the excircle of a spring pin respectively, then the brake assembly to be machined is arranged on a positioning mandrel arranged on a grinding machine in advance for positioning, a proper pressing block and a proper cushion block are placed, and equipment is started to finish clamping, positioning and grinding of the brake assembly.
The inventor discovers that:
the locking pull rod used at present for grinding and tensioning the brake grinding assembly is relatively fixed in structure and cannot be adjusted, different types of locking pull rods with different special models need to be used, namely one locking pull rod cannot be suitable for grinding and tensioning of various brake assemblies, the locking pull rod is not universal, operation is inconvenient, production efficiency is low, and production cost is increased.
Disclosure of Invention
In order to solve the problem of locking pull rod commonality, the utility model provides a locking pull rod for stopper assembly excircle grinding.
Therefore, the technical scheme of the utility model is that: the utility model provides a locking pull rod for brake assembly cylindrical grinding which characterized in that: comprises a double-head screw rod arranged in the middle and threads at two ends are arranged reversely, the two ends of the double-head screw rod are respectively connected with a connecting seat in a threaded manner, connecting shafts are symmetrically arranged at two sides of the connecting seat, the connecting shafts are connected with drag hooks through threads and are fixed through nuts,
the draw hooks on the connecting seats at the two ends of the double-headed screw are arranged in a reverse extending mode along the direction far away from the double-headed screw, and hook-shaped structures matched with the spring pins are arranged at the end parts of the draw hooks.
The technical scheme is further improved as follows: the connecting shaft between the connecting seat and the draw hook is provided with an elastic gasket, so that the requirements of spring pins with different lengths are met, the stress balance is ensured, and the universality is improved.
The technical scheme is further improved as follows: the cross section of the middle part of the double-head screw is square or regular hexagon, so that slipping is prevented during rotation.
The technical scheme is further improved as follows: the nut is a hexagonal thin nut, and fine teeth of the nut have the functions of loosening and improving fine adjustment precision.
Has the advantages that: the utility model discloses the structure can be suitable for the grinding of different varieties stopper assemblies taut, and the commonality is strong, and convenient operation improves production efficiency, reduction in production cost.

Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings, but the embodiment should not be construed as limiting the present invention.
The utility model discloses as shown in fig. 1 to 3:
a locking pull rod for grinding the external circle of a brake assembly comprises a double-head screw 1 arranged in the middle and reverse threads arranged at two ends, wherein two ends of the double-head screw are respectively in threaded connection with a connecting seat 2, connecting shafts are symmetrically arranged at two sides of the connecting seat, a drag hook 4 is connected to each connecting shaft through a thread and is fixed through a nut 5,
the draw hooks on the connecting seats at the two ends of the double-headed screw are arranged in a reverse extending mode along the direction far away from the double-headed screw, and hook-shaped structures matched with the spring pins are arranged at the end parts of the draw hooks.
And an elastic gasket 6 is arranged on the connecting shaft between the connecting seat and the draw hook, so that the requirements of spring pins with different lengths are met, the stress balance is ensured, and the universality is improved.
The cross section of the middle part of the double-head screw is square or regular hexagon, so that slipping is prevented during rotation.
The nut is a hexagonal thin nut, and fine teeth of the nut have loosening function.
The utility model discloses a use method:
as shown in fig. 3: when the device is used, the positioning support shaft B is arranged in a camshaft hole E of a brake assembly H to be processed in advance, the width of 4 drag hooks is adjusted to be matched with the length of a spring pin D through manual rotation, the width between the two drag hooks on the same side is fixed through screwing a hexagonal thin nut, then the double-head screw rod is rotated to adjust the locking pull rod to be in a proper length, the 4 drag hooks are hooked at proper positions of the excircle of the spring pin respectively, the stress balance of the two ends is ensured, and then the double-head screw rod is rotated to tighten the brake assembly to be processed; then the brake assembly to be processed is arranged on a positioning mandrel C which is arranged on a grinding machine in advance for positioning, a proper pressing block and a proper cushion block are placed, and the assembly is clamped, positioned and ground by starting equipment.
Those skilled in the art will appreciate that the details of the present invention are not described in detail herein.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
