Detailed Description
The utility model is further described below with reference to the drawings and examples.
The embodiment of the clamping fixture for machining the U-shaped bolt comprises a lower tire which is connected with an oil press working platform in use and used for placing a threaded rod, and an upper tire which is connected with an oil press lifting platform in operation and is used for pressing the threaded rod downwards by being matched with the lower tire.
As shown in fig. 1, the lower tire comprises a base 1, and positioning seats 2 in the form of a left vertical plate and a right vertical plate are arranged on the base 1. The upper side of the positioning seat 2 is provided with a plurality of positioning lower grooves 2-1 which are used for placing threaded rods and are arranged in parallel, the positioning lower grooves 2-1 on the positioning seat 2 on the left side and the right side are in one-to-one correspondence, and the corresponding limiting grooves are coaxially arranged.
The base 1 is connected with a base connecting plate 3 in a welding mode. Lower bolt holes are longitudinally formed in the base connecting plate 3. When in use, the lower tire is fixed on the working platform of the vertical oil press through the bolts penetrating through the lower bolt holes.
As shown in fig. 2, the upper tire includes a supporting body 7, an upper tire connecting plate 6 fixed at the upper end of the supporting body 7, and a pressing plate 5 fixed at the lower end of the supporting body 7. The width of the pressing plate 5 is smaller than the distance between the positioning seats at the left side and the right side. The difference between the distance between the left and right positioning seats and the width of the pressing plate 5 is twice the diameter of the threaded rod. The lower side surface of the pressing plate 5 is provided with positioning upper grooves 5-1 which are in one-to-one correspondence with the positioning lower grooves 2-1.
When in use, the corresponding positioning lower groove 2-1 is aligned with the positioning upper groove 5-1 up and down, and is used for positioning the same threaded rod. The initial stage of pressing down the threaded rod by the pressing plate 5 mainly depends on the positioning lower groove 2-1, the contact between the threaded rod and the positioning lower groove 2-1 in the bending process is gradually reduced, and the positioning depends on the inner end part of the positioning lower groove 2-1 and the outer end part of the positioning upper groove 5-1.
An upper bolt hole 6-1 is longitudinally formed in the upper tire connecting plate 6. When in use, the upper tire is fixed on the lifting platform of the vertical oil press through bolts passing through the upper bolt holes 6-1.
