Description
技术领域 technical field
本实用新型涉及发动机缸体技术领域，特别是一种发动机缸体的锁紧夹具。 The utility model relates to the technical field of engine cylinders, in particular to a locking fixture for engine cylinders.
背景技术 Background technique
汽车发动机缸体在加工过程中要通过缸孔及其端面进行装夹，就目前的技术手段来看，还很难有一个好的方式。 The cylinder block of the automobile engine needs to be clamped through the cylinder hole and its end face during the processing process. As far as the current technical means are concerned, it is still difficult to find a good way.
传统的缸体四面夹具，均采用螺杆穿过缸孔、压板压紧顶面的方式进行吊装装夹。因螺杆较长，缸体较重，采用吊装的方式装夹产品，易造成缸孔的碰伤，甚至造成产品报废。 The traditional clamps on all four sides of the cylinder block are hoisted and clamped in the way that the screw rod passes through the cylinder hole and the pressure plate presses the top surface. Because the screw rod is long and the cylinder body is heavy, the product is clamped by hoisting, which may easily cause damage to the cylinder hole, and even cause the product to be scrapped.

A pressing plate and a nut are sleeved on the threaded section, and a rotating nail perpendicular to the locking screw is arranged on the top of the locking screw.
作为优选，所述锁紧螺杆底部两侧设置与其垂直的锁紧钉，所述锁紧座上中央开设与锁紧螺杆大小匹配的圆孔以及将该圆孔对称剖分为两部分的竖直缝，竖直槽底部还沿顺指针方向开设水平缝，竖直缝和水平缝的宽度大于或等于锁紧钉。 As a preference, locking nails perpendicular to the locking screw are provided on both sides of the bottom of the locking screw, and a round hole matching the size of the locking screw is provided in the center of the locking seat, and a vertical hole that symmetrically divides the round hole into two parts. seam, the bottom of the vertical groove also provides a horizontal seam along the direction of the pointer, and the width of the vertical seam and the horizontal seam is greater than or equal to the locking nail.
综上所述，由于采用了上述技术方案，本实用新型的有益效果是： In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
锁紧螺杆插入锁紧座然后握住旋转钉进行旋转，锁紧螺杆底部的锁紧钉与锁紧座锁紧配合，从而达到锁紧的目的；再通过压板、螺母可将发动机缸体固定、压紧；装夹方便、快捷，效率高，且还可降低夹具碰伤发动机缸体上缸孔。 The locking screw is inserted into the locking seat and then rotated by holding the rotating nail. The locking nail at the bottom of the locking screw is locked and matched with the locking seat to achieve the purpose of locking; and then the engine block can be fixed by the pressure plate and the nut. Compression; clamping is convenient, fast, and efficient, and it can also reduce the impact of the clamp on the upper cylinder hole of the engine block.
