[0001] The utility model belongs to the field of machining, and particularly relates to a replaceable probe head positioner for numerically controlled turning of projectile shells. Background Art

[0002] With the progress of the times, the structure of the projectile shell of the artillery has become increasingly complex, and the product precision and processing difficulty have also been continuously improved. In order to ensure the product precision and qualification rate, production units have designed different positioners for numerically controlled turning according to different types of products and processes. The positioners cannot be replaced with each other, resulting in a reduction in the production change efficiency.

[0003] Such as Figure 1 、 Figure 2 、 Figure 3 As shown, when the product is changed, the positioner also needs to be replaced as a whole. Therefore, it is necessary to design a positioner that can meet the use of multiple products and multiple processes. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a positioner that can meet the use of multiple products and multiple processes during the numerically controlled turning of the projectile shell.

[0005] To solve the above technical problem, the specific technical solution of the utility model is as follows:

[0006] A replaceable probe head positioner includes a main body structure and a replaceable probe head; the main body structure includes a probe body 1, a spring 2, a sliding sleeve 3, a plug 4, a nut 5 and a positioning rod 6; the sliding sleeve 3 is sleeved on the outer surface of the probe body 1, and the two are in sliding fit; the spring 2 is sleeved on the probe body 1, its left end contacts the protrusion at the left end of the probe body 1, and the right end contacts the left end face of the sliding sleeve 3; the positioning rod 6 is fixedly arranged at the right end of the probe body 1, and the plug 4 is fixed on the positioning rod 6 through the nut 5; the replaceable probe head is fixedly arranged at the left end of the probe body 1.

[0007] Preferably, the replaceable probe head is disc-shaped.

[0008] Preferably, the replaceable probe head is sleeve-shaped.

[0009] Preferably, the replaceable probe head is rod-shaped.

[0010] Wherein, the outer diameter of the plug 4 is greater than the inner diameter of the sliding sleeve 3.

[0011] The utility model has the following advantages: Positioning during the processing of different products and different processes can be achieved only by replacing the probe head, which is convenient, fast and efficient. Description of the Drawings

[0022] In order to better understand the purpose, structure and function of the present utility model, the following will make a more detailed description of the present utility model in conjunction with the accompanying drawings.

[0023] As Figure 8 shown, the replaceable measuring rod head locator of the present utility model includes a main structure and a replaceable measuring rod head.

[0024] As Figure 4 shown, the main structure includes a measuring rod body 1, a spring 2, a slide sleeve 3, a plug 4, a nut 5 and a positioning rod 6. The assembly process is as follows: First, the spring 2 is sleeved on the measuring rod body 1 until the raised end face; Second, the measuring rod body with the spring sleeved is inserted into the slide sleeve 3; Third, the slide sleeve 3 is installed in the boring tool seat, generally matching the corresponding diameter change according to the inner diameter of the tool seat, and the slide sleeve is fixed in the tool seat with screws; Fourth, the positioning rod 6 is screwed into the plug 4, and the nut 5 is screwed into the positioning rod 6 until it presses against the end face of the plug 4; Fifth, the whole composed of the plug and the positioning rod nut is screwed into the measuring rod body; Sixth, select the required measuring rod head and fix the measuring rod head at the left end of the measuring rod body.

[0025] As Figure 9As shown, during actual use, preparation before positioning: After clamping the workpiece, start the positioner program (pre-written and input in the machine tool in advance). For a numerically controlled machine tool with a rear tool post, the positioner is at its initial position in the upper right. Rotate the tool to the tool position where the positioner is located through tool setting, and then perform the positioning work.

[0026] Working process:

[0027] 1. The positioner makes rapid movements along the X-axis and Z-axis and moves to a position close to the positioning surface.

[0028] 2. Perform slow feed until the end face of the measuring rod head contacts the workpiece positioning surface.

[0029] 3. Continue to feed to compress the spring until the positioning rod contacts the proximity switch installed under the tool post, forming signal transmission. The feed stops, and the Z-axis position coordinate is determined, completing the positioning function.

[0030] 4. Then, the positioner returns to the initial position along the previous route, completing the entire working process.

[0031] Figures 5 - 7 There are three replaceable measuring rod heads, respectively corresponding to Figures 1 - 3 the positioning for machining in these three cases. Among them, Figure 5 and Figure 7 require a hexagon socket head screw during assembly.

[0032] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, for those skilled in the art, without departing from the principle of the present invention, several modifications and improvements can still be made, and these should also be regarded as falling within the protection scope of the present invention.
