This invention discloses a heat treatment method and apparatus for engine housings. The method includes: performing a temperature test on a welded test ring; clamping the engine housing to be treated onto a transmission support mechanism and adjusting the relative position of the engine housing and the induction coil to ensure that the axis of the engine housing is coaxial with the axis of the induction coil; positioning the circumferential weld to the heating center region of the induction coil; controlling the transmission support mechanism to rotate the engine housing around its own axis and performing local induction tempering treatment on the circumferential weld through the induction coil; after the current circumferential weld has completed local induction tempering treatment, adjusting its position along the axial direction of the engine housing to allow the next circumferential weld to enter the heating center region, and repeating the local induction tempering treatment until each circumferential weld has completed local induction tempering treatment, thereby solving the problem of poor process compatibility between the heat treatment method and the process of thin-walled housings with large aspect ratio in the prior art.

This application provides a punching and bending device, relating to the field of punching and bending technology. It includes a lower die base and an upper die base for connection with a punching head. The lower die base is equipped with a punch and an outer demolding assembly, while the upper die base is equipped with an inner demolding assembly and several punching posts. The inner demolding assembly cooperates with the punch to apply pressure and bend the workpiece placed on the punch. The outer demolding assembly cooperates with the punching posts to punch the bent workpiece. This invention integrates the inner demolding assembly and punching posts in the upper die base and the punch and outer demolding assembly in the lower die base, completing bending and punching sequentially in one punching stroke. Compared with existing technologies, this reduces the clamping and transfer of sheet metal, reduces process turnaround time, improves production efficiency, and simultaneously reduces the number of sheet metal processing positioning steps, thus improving processing accuracy.

This utility model discloses an auxiliary fixture for coordinate measuring machine (CMM) measurement of a motorcycle frame, relating to the field of motorcycle frame inspection technology. It solves the problems of cumbersome operation, low efficiency, large errors, and inconsistent benchmarks in existing measurement methods. The fixture includes a front support mechanism, a rear support mechanism, and a mandrel. The front support mechanism includes a height-adjustable support platform, with height adjustment achieved via a lead screw, guide rail, and rotating handle. The rear support mechanism includes symmetrical left and right support seats connected by a connecting rod. The support seats have V-grooves and are fixed to the measurement platform by adjustable strong magnets. The mandrel passes through a hole at the rear of the frame and is placed in the V-groove. This fixture can accurately position the frame, adapt to the height requirements of different frame types, ensure stable rear positioning, unify the design, manufacturing, and inspection benchmarks, and improve measurement efficiency and accuracy. It is suitable for the inspection of four-wheeled and two-wheeled motorcycle frames.

The invention relates to a spraying device for production of a trimmer shell. Comprising a spraying box, and the top end of the spraying box is rotationally connected with a cover plate; the top end of the cover plate is fixedly connected with a sealing rubber strip; an observation window is formed in the side wall of the spraying box; a water outlet is fixedly connected to the side wall of the spraying box; the side wall of the spraying box is fixedly connected with a pair of storage boxes; a pair of nozzles is arranged on the inner side wall of the spraying box; the spray head is connected to the storage box through a pipeline; the bottom end of the spraying box is rotationally connected with a first fixing rod. The side wall of the first fixing rod is fixedly connected with a pair of electric push rods; the side wall of the first fixing rod is slidably connected with a supporting ring. The supporting ring is pushed through the electric push rod, so that the ejector rod forms uniform supporting force on the inner side of the shell, the shell can be quickly fixed, the preparation time is shortened, and the defects after spraying caused by the fact that a clamp shields an outer spraying surface during spraying of a spray head due to clamping and fixing from the outer side during shell fixing are reduced.

The utility model provides a bridge support replacing, taking and delivering device which comprises a support transferring assembly used for transferring a support, the support transferring assembly comprises a support telescopic part, a support driving part and a support picking part, the support driving part is located on the support telescopic part, the support picking part is connected with the support driving part, and the support driving part is located on the support telescopic part. The support driving part is used for driving the support picking part so that the support picking part can clamp a support, and the support telescopic part is used for achieving synchronous movement of the support driving part and the support picking part. According to the utility model, support transfer and jack transfer are carried out separately, manual intervention is effectively reduced, the support replacement efficiency and safety are improved, the support pickup part clamps the support, and the support telescopic part drives the support driving part and the support pickup part to operate simultaneously, so that not only can large-stroke large-tonnage support replacement in a narrow space be realized, but also the replacement efficiency and the replacement safety of the large-stroke large-tonnage support can be improved. And moreover, the support moves more stably during replacement, and the replacement efficiency and precision of the support are high.
