Description
Technical Field
The utility model belongs to the technical field of the cylinder cap processing, concretely relates to interfere behind cylinder cap tappet hole processing and get rid of the device that the condition carries out eccentric detection.
Background
In the cylinder cover tappet hole machining process, the interference part of multiple materials in the tappet hole is removed according to the requirement of a customer, and subsequent machining is prevented from being finished. The aperture diameter of the large end of the tappet hole is phi 23.5, the aperture diameter of the small end of the tappet hole is phi 23, and the size of the interference aperture to be removed inside the tappet hole is phi 25.5. Due to the fact that the interference removing hole diameter in the middle is large and the hole diameters at two ends are small, the common gauge cannot measure after machining. If three-coordinate detection is adopted, if interference removal is not clean due to too deep aperture, the condition that the measuring needle is damaged can be caused. It is therefore necessary to design a dedicated eccentricity detection tool.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a cylinder cap tappet hole that can be used for tappet hole to remove the detection after interfering is got rid of and is interfered eccentric detection device is provided.
In order to solve the technical problem, the technical scheme of the utility model is that: cylinder cap tappet hole goes to interfere eccentric detection device, including can running through the detection axle that stretches into to the tappet hole, the both ends of detecting the axle set respectively with the main aspects in tappet hole, the main aspects location bush and the tip location bush that the tip aperture suited, the fixed eccentric detection head that is provided with in middle part of detecting the axle.
Preferably, one end of the detection shaft extends to form a grip.
Preferably, the grip portion is provided with an anti-slip structure.
Since the technical scheme is used, the utility model discloses following beneficial effect at least has: the cylinder cap is from tappet hole process processing completion back, the operator will detect the axle and stretch into in the tappet hole from the tappet hole main aspects of work piece, it fixes a position in the tappet hole main aspects to place main aspects positioning bush simultaneously, it fixes a position in the tappet hole tip to place tip positioning bush, will detect the axle from the main aspects to the tip slow movement in tappet hole, and rotate and detect the axle, when work piece internal interference gets rid of thoroughly, then the eccentric detection head of detecting the axle can't remove or rotate, thereby detect out the defective work. The utility model discloses structural design is simple, operation convenient to use, and on-the-spot operator and inspector can select the interference fast through this detection device and get rid of not thorough product, have not only solved the unable problem that detects of three-dimensional, have greatly improved detection efficiency simultaneously to product quality's stability has been guaranteed.

Detailed Description
The invention is further explained below by referring to the drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention have been described by way of illustration only. Needless to say, a person skilled in the art realizes that the described embodiments may be modified in various different ways, without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive on the scope of the claims.
As shown in fig. 1 and 4, the cylinder head tappet hole interference-removing eccentricity detection apparatus includes a detection shaft 1, which can penetrate through and extend into a tappet hole 51 of a workpiece 5 (cylinder head), a large end positioning bushing 2 and a small end positioning bushing 3 are respectively provided at two ends of the detection shaft 1, the large end positioning bushing 2 is adapted to a large end hole diameter of the tappet hole 51, and the small end positioning bushing 3 is adapted to a small end hole diameter of the tappet hole 51; the detection shaft 1 is positioned in the radial direction through the large end positioning bush 2 and the small end positioning bush 3, so that the detection accuracy can be ensured; referring to fig. 2, an eccentricity detection head 4 is fixedly disposed in the middle of the detection shaft 1, and when the detection shaft 1 is rotated, whether the interference part inside the tappet hole is completely removed can be determined by the eccentricity detection head 4.
Referring to fig. 1, in order to facilitate the holding of an operator, a holding portion 11 extends from one end of the detection shaft 1, and an anti-slip structure such as an anti-slip pattern or a protrusion is disposed on the holding portion 11.
Referring to fig. 3 and 4, the specific application method of the present invention is as follows: workpiece 5 is from the tappet hole process processing completion back, the operator will detect axle 1 and stretch into in the tappet hole from the tappet hole 51 main aspects of workpiece 5, it fixes a position to place main aspects position bush 2 in tappet hole 51 main aspects simultaneously, it fixes a position to place tip positioning bush 3 in tappet hole 51 main aspects, then will detect axle 1 from the main aspects to the tip slow movement of tappet hole 51, and rotate and detect axle 1, when the work piece internal interference (detection position 52) gets rid of thoroughly, then detect the unable removal or the rotation of epaxial eccentric detection head 4 of 1, thereby detect out the defective work.
The utility model discloses structural design is simple, operation convenient to use, and on-the-spot operator and inspector can select the interference fast through this detection device and get rid of not thorough product, have not only solved the unable problem that detects of three-dimensional, have greatly improved detection efficiency simultaneously to product quality's stability has been guaranteed.
The basic principles, main features and advantages of the present invention have been shown and described above.
