Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a tooling for testing drilling of annular radial holes. Background Art

[0002] For some circular ring workpieces, there are many radial holes and the size requirements are high. The frequency of replacing milling cutters, boring blades and reamers is high during the processing, and the number of tool replacements is large. After replacing the tools during fine processing, the boring cutter and reamer need to be trial bored and trial reamed. During operation, the trial tool parts must be pressed and fixed on the workbench first, and the bottom hole must be manually processed, and then trial boring and trial reaming are performed on the basis of the bottom hole. The operation steps are cumbersome, time-consuming, and inefficient, and the operator's ability is required to be high. In the actual processing process, the trial tool often fails to achieve the expected effect due to the uneven ability of the operator, which leads to the radial hole failing to meet the requirements.

[0015] refer to Figure 1 A circular radial hole test drilling tool includes a support base 1 for supporting a workpiece 7. The support base 1 is in a circular shape as a whole, and a step for supporting the workpiece 7 is provided on the outer edge. The side wall diameter of the step is equal to the inner diameter of the workpiece 7, which is convenient for radial positioning of the workpiece 7. A plurality of clamping components 2 for clamping the workpiece 7 are connected to the support base 1. On this basis, it should be understood that when clamping, the workpiece 7 is prevented from being on the support base 1 and is clamped by the clamping component 2.

[0016] The clamping component 2 of this embodiment includes a clamping block 201, a locking screw 202 and a spacer 203. The spacer 203 is arranged on the clamping block 201 and abuts against the top of the support base 1. The clamping block 201 is provided with a connecting hole. The locking screw 202 passes through the connecting hole and is connected to the support base 1. Tightening the locking screw 202 can make the clamping block 201 clamp the top of the workpiece 7. In other embodiments of the utility model, the clamping component 2 can also use other structures of the prior art to achieve clamping, such as using a manual clamp.

[0017] On the basis of the above, the raising member 203 of the present embodiment is a screw, the stem of the screw is connected to the clamping block 201 by a thread, and the head of the screw is against the top of the support base 1. It is worth noting that, on the one hand, the raising member 203 directly adopts a screw, which can save costs; on the other hand, it is convenient to change the height of the clamping block 201 by turning the raising member 203. The greater the distance between the screw head and the clamping block 201, the higher the height from the clamping block 201 to the top of the support base 1, which is convenient for adapting to workpieces 7 of different axial lengths.

[0018] In this embodiment, the locking screw 202 is a flange screw, that is, the head of the screw is integrally connected with a flange. When the locking screw 202 is tightened, the flange contacts the head of the pressing block 201, increasing the contact area and ensuring the locking force. Of course, in other embodiments, the locking screw 202 can also be an ordinary screw plus a gasket to ensure the locking force.

[0019] Furthermore, the connection hole on the clamping block 201 for connecting the locking screw 202 is a waist-shaped hole. This arrangement facilitates adjustment of the position of the clamping block 201 in the radial direction of the support base 1, thereby adapting to workpieces 7 of different sizes and improving applicability.

[0020] In this embodiment, a fixing block 3 is fixed (for example, welded or screwed) on the top of the support base 1, to which a test tool block 4 is detachably connected, and a test drill bottom hole 401 is provided on the test tool block 4. In this way, the operator can directly perform test boring and test reaming on the test drill bottom hole 401 on the test tool block 4, saving the steps of fixing the test tool block 4 and manually drilling the bottom hole, facilitating the standardization of the test tool steps and improving the processing efficiency. Moreover, after each test tool block 4 is connected to the fixing block 3, the position is unified, which has low requirements on the operator's ability and facilitates improving the overall quality of the radial hole.

[0021] The connection method of the test knife block 4 and the fixed block 3 is as follows: the test knife block 4 and the fixed block 3 are connected by at least one positioning pin 5 and at least one connecting screw 6. In this embodiment, considering the size of the test knife block 4, only one positioning pin 5 and one connecting screw 6 are used to achieve the connection between the two. The test knife block 4 and the fixed block 3 are provided with pin holes at corresponding positions, and the positioning pin 5 is inserted into the pin hole. The test knife block 4 is provided with a connecting hole, and the fixed block 3 is provided with a screw hole at the position corresponding to the connecting hole. The connecting screw 6 is connected in the connecting hole and the screw hole. In actual applications, when replacing the test knife block 4, the test knife block 4 can be removed by simply removing the connecting screw 6.

[0022] It is easy to understand that in other embodiments of the present invention, if there is enough space, the number of positioning pins 5 and connecting screws 6 between the test knife block 4 and the fixing block 3 can also be increased.

[0023] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
