Description

  The present invention relates to a processing dimension setting jig and a manufacturing method of a processing dimension setting jig.

  A control tool for controlling the drilling depth of a drill is described in Utility Model Registration No. 3136852 (Patent Document 1). The control tool shown in FIG. 1 of Patent Document 1 attaches a cylindrical body 10 to a drill 28 with a set screw 12, and the cylindrical body 10 regulates the processing dimensions of the drill 21.

  Japanese Patent Laid-Open No. 09-029526 (Patent Document 2) has a structure in which a cylindrical stopper 2 is attached to a drill blade body 1 with a tightening screw 13 as shown in FIGS. A hand drill D is disclosed. The stopper 2 hits the opening edge 10a of the target member W to restrict the movement of the drill blade body 1.

  Japanese Laid-Open Patent Publication No. 11-058115 (Patent Document 3) discloses a drilling tool 1 in which a stopper 5 for restricting the movement of the drill 1 is attached to the shank 4 of the drill 1. The stopper 5 is attached using screws 6 as shown in FIG.

  Furthermore, Japanese Patent Application Laid-Open No. 11-090784 (Patent Document 4) shows a structure in which the fixing ring 1 is attached to the holder portion 12 of the step drill 10.

Utility Model Registration No. 3136852 JP 09-029526 A Japanese Patent Laid-Open No. 11-058115 Japanese Patent Laid-Open No. 11-090784

  The fixing ring 1 described in Patent Document 4 is for identifying the diameter of the drill 1, and does not set or regulate the processing dimensions of the drill.

  Moreover, the thing of patent document 1 and patent document 3 is a structure which stops the cylindrical body 10 and the stopper 5 with the set screw 12 or the bis | screw 6. FIG. Since the drill rotates during use, there is a drawback that the set screw 12 and the screw 6 are easily loosened. If it is used without knowing that it has been loosened, the set screw 12 and the screw 6 may come off, which is very dangerous.

  Moreover, the drill of patent document 2 is a structure attached with the stopper applied to the base of the hand drill D. For this reason, the slit 9 is formed in the stopper 2, and the groove | channel 11 which fits into the slit 9 of this stopper 2 is formed in the base part side of the hand drill. As a result, both the stopper 2 and the hand drill D to which the stopper 2 is attached have a complicated configuration, which requires additional configuration and processing. If additional configuration or processing is required, it will increase the price, so we want to suppress this additional configuration and processing as much as possible.

  An object of the present invention is to solve the above-described problems and provide a machining dimension setting jig that has a simple structure and is not likely to come off, and a manufacturing method for the machining dimension setting jig.

The present invention is for solving the above problems, and the processing dimension setting jig of the present invention is:
A processing dimension setting jig attached to a drill blade,
A portion used by the drill blade when exposed to the drill is exposed, and a stopper that covers the unused portion of the blade is provided.

Further, the manufacturing method of the processing dimension setting jig of the present invention,
A manufacturing method of a processing dimension setting jig which is attached to a drill blade and used to regulate a processing dimension,
An attachment step for attaching the tubular member to the drill blade;
A setting step for setting the position of the cylindrical member by filling a gap in the base of the drill; and
A cutting step of cutting the cylindrical member so as to expose a drill blade of a portion used for processing;
And a removing step of removing the end of the cut cylindrical member.

  According to the present invention configured as above, the following effects can be obtained.

  According to the manufacturing dimension setting jig and the manufacturing dimension setting jig according to the present invention, since the stopper having a simple cylindrical structure is used, the price of the stopper itself and the processing cost are kept low. be able to. Further, since the cylindrical stopper is attached to the drill blade, the stopper can be attached to the drill without the need for a separate screw or the like.

  1st Embodiment of this invention is described based on FIGS.

  FIG. 1 is an explanatory diagram illustrating a processing dimension setting jig according to the first embodiment. Moreover, FIG. 2 is explanatory drawing which shows the state which attached the jig for the said process dimension setting to the drill. Moreover, FIG. 3 is explanatory drawing of the target object processed using the jig for the said process dimension setting.

  As shown in FIGS. 1 and 2, the processing dimension setting jig 101 is formed of a cylindrical synthetic resin material. As this synthetic resin material, a flexible material is used.

  As shown in FIG. 1 and FIG. 2, the drill 111 for processing a workpiece includes a drill base (a base of the drill) 112 and a blade 113. The drill 111 processes the processing object 121 with the blade 113. This process is a process of making a through hole or a hole that becomes a depression.

  The inner diameter of the processing dimension setting jig 101 is set to be the same as or slightly smaller than the outer diameter of the blade 113. 2 is a part where the blade 113 is not covered with the processing dimension setting jig 101 of the length dimension P, that is, the length of the part where the blade 113 is exposed. For this reason, the processing object 121 is processed so as to have this processing dimension Q. The end portion 102 of the processing dimension setting jig 101 serves as a stopper for restricting the moving direction of the drill 111 during the processing operation. For this reason, the processing dimension setting jig 101 is sometimes called a stopper.

  A processing target 121 shown in FIG. 3 has a target dimension R for processing. At the time of machining, an operator (user) moves the blade 113 of the drill 111 so that the target value dimension R and the machining dimension Q coincide with each other manually or automatically. If the moving dimension is too large, the workpiece 121 is excessively processed, resulting in a defective product. On the other hand, if the movement dimension is too small, the processing object 121 will be insufficiently processed, and further processing will be required, which will be troublesome twice. For this reason, in the processing by the drill 111, if only the target value dimension R can be processed accurately, it is possible to prevent defective products and to prevent troubles twice.

  A processing dimension setting jig 101 formed in advance to a necessary length dimension P is used by being attached to a blade 113 of a drill 111 as shown in FIG.

  A machining state using the machining dimension setting jig 101 configured as described above will be described with reference to FIGS. 4 and 5. FIG. 4 is an explanatory view showing a state in which an object is machined using the machining dimension setting jig. Moreover, FIG. 5 is explanatory drawing which shows the state which processed the target object using the jig | tool for a process dimension setting.

  As shown in FIG. 4, the operator processes the processing object 121 in a state where the processing dimension setting jig 101 is attached to the blade 113 of the drill 111. When the operator moves the drill 111 in the direction of machining, the workpiece 121 is machined by the blade 113 of the drill 111. When the operator further moves the drill 111 and moves the blade 113 of the drill 111 to the target value dimension R, the end portion 102 of the processing dimension setting jig 101 hits the processing object 121 as shown in FIG. . Thereby, the worker can understand the timing of finishing the machining operation. Thus, since the processing dimension setting jig 101 functions as a stopper, it is possible to perform drilling with a depth of a predetermined dimension (target value dimension R). For this reason, there is no fear of drilling with a depth exceeding a predetermined dimension or fear of drilling with insufficient machining dimensions.

  Also, manual drills that move the blade by the operator and drills that the operator controls the drive device that moves the blade are often affected by the skill of the operator, and machining accuracy is kept constant. Difficult to keep. However, if this processing dimension setting jig 101 is used, the processing accuracy can be kept substantially constant without being affected by the skill of the operator. In addition, since the end of the processing dimension setting jig 101 hits the processing target 121 and the timing of the end of the processing operation is known, the operation time can be shortened.

  Furthermore, since the processing dimension setting jig 101 does not use a separate member such as a screw as an attachment member, there is no possibility that the attachment member of the processing dimension setting jig 101 is detached during use. Further, the processing dimension setting jig 101 itself has a cylindrical structure, so that it is less likely to come off. For this reason, this processing dimension setting jig 101 can be used as the processing dimension setting jig 101 with less risk of detachment and improved safety.

  Moreover, the use state when processing a different processing object using this processing dimension setting jig 101 will be described with reference to FIGS. In addition, FIG. 6 is explanatory drawing which shows a different workpiece. Moreover, FIG. 7 is explanatory drawing which shows the state which processed the different process target object using the jig | tool for a process dimension setting. Furthermore, FIG. 8 is explanatory drawing which shows the state which processed the different process target object, without using the jig | tool for the said process dimension setting.

  As shown in FIG. 6, the workpiece 131 has a relatively small distance S between the upper wall 132 and the lower wall 133. For this reason, if processing is performed by moving the blade 113 of the drill 111 vigorously, the lower wall 133 may be processed unnecessarily. In particular, as shown in FIG. 8, when processing is performed without attaching the processing dimension setting jig 101, the lower wall 133 is likely to be processed unnecessarily. Therefore, it is necessary to carefully perform such processing of the processing object 131.

  When machining such a workpiece 131, machining is performed using the machining dimension setting jig 101 in which the blade 113 of the drill 111 is set so that only a predetermined dimension is exposed in advance. In the drill 111 to which the processing dimension setting jig 101 is attached, the movement of the blade 113 of the drill 111 is regulated by the end 102 of the processing dimension setting jig 101 as shown in FIG. The blade 113 of the drill 111 does not reach the lower wall 133. For this reason, the fear that the drill 111 is moved too much and the lower wall 133 is damaged can be prevented.

  In the case of processing the workpiece 131, the processing dimension is slightly larger than the thickness of the upper wall 132 because of the processing for forming the through hole 134. On the other hand, the target value dimension may be in a range that is slightly larger than the thickness of the upper wall 132 and that the blade 113 of the drill 111 does not reach the lower wall 133. For this reason, unlike the processing of the processing object 121, the processing dimension does not necessarily match the target value dimension.

  Next, a manufacturing method of the processing dimension setting jig 902 according to the second embodiment of the present invention will be described with reference to FIGS. In addition, FIG. 9 is explanatory drawing for showing the manufacturing method of the jig | tool for a process dimension setting which is 2nd Embodiment. Moreover, FIG. 10 is a side view which shows the state which attached the cylindrical member to the drill in the manufacturing method. FIG. 11 is a side view showing a state in which a cylindrical member is temporarily cut in accordance with the tip of the drill in the manufacturing method. Furthermore, FIG. 12 is a side view showing a state in which a necessary part of the cylindrical member is cut in the manufacturing method.

  A cylindrical member 901 shown in FIG. 9 is formed from a cylindrical synthetic resin material. An inner diameter X of the cylindrical member 901 is set to be slightly smaller (for example, 1.0 mm to 2.0 mm smaller) than an outer diameter Y of a drill described later. Further, the length dimension P1 is formed to be slightly longer than the length dimension Q1 of the blade 113 of the drill 111. Moreover, since this cylindrical member 901 is formed of a synthetic resin material, it has stretchability and flexibility. Further, as this synthetic resin material, it is desirable to use a vinyl resin when the adhesion for mounting is particularly taken into consideration. Since the cylindrical member 901 is formed of a synthetic resin material having elasticity and flexibility, even if the inner diameter X is formed slightly smaller than the outer diameter Y of the blade 113 of the drill 111, the blade 113 Attachment is relatively easy, and even after installation, it is in close contact and difficult to come off.

  As shown in FIG. 10, the cylindrical member 901 uses a material that is slightly longer than the blade 113 of the drill 111 when attached to the blade 113 of the drill 111. This is so that it can also be used for a drill having a long blade.

  A cylindrical member 901 </ b> A shown in FIG. 11 shows a state where the end 901 </ b> B is cut so as to substantially coincide with the tip of the blade 113 of the drill 111. That is, the cylindrical member 901A shown in FIG. 11 is temporarily cut.

  The processing dimension setting jig 902 shown in FIG. 12 is a state in which the cylindrical member 901A is pressed against the drill base 112 without a gap, and is cut so that only a necessary dimension remains from the cylindrical member 901A. The necessary dimension is a dimension that exposes the part of the blade 113 necessary for processing (the part of the target value dimension Q2) and covers the other part. The target value dimension Q2 is a dimension from the end 902A of the processing dimension setting jig 902 to the tip of the blade 113 of the drill 111.

  Next, a manufacturing method of the processing dimension setting jig 902 will be described.

  First, the cylindrical member 901 shown in FIG. 9 is attached to the blade 113 of the drill 111 as shown in FIG. At this time, since the inner diameter X of the cylindrical member 901 is smaller than the outer diameter Y of the blade 113 of the drill 111, there is a slight resistance to the attachment. However, in the attached state, the deviation or detachment is caused by the resistance. Is prevented.

  Temporary cutting is performed with the tubular member 901 in close contact with the drill base 112 without any gap. As shown in FIG. 11, the temporary cutting is a cutting in which the tip of the blade 113 and the end 902B of the cylindrical member 901A are substantially aligned.

  When provisional cutting is performed, the tip of the blade 113 can be seen, so that it is easy to set dimensions for cutting unnecessary portions of the cylindrical member 901A. As shown in FIG. 10, in the state where temporary cutting is not performed, the tip of the blade 113 is difficult to see, so it is somewhat difficult to set dimensions for cutting.

  In the state after the temporary cutting shown in FIG. 11, next, the cylindrical member 901A is cut so that a necessary dimension remains, and the cut end portion is removed. Thereby, as shown in FIG. 12, the processing dimension setting jig 902 is completed.

  Thus, this 2nd Embodiment is a manufacturing method of the jig | tool 902 for a process dimension setting attached to the blade 113 of the drill 111, and used in order to regulate a process dimension, Comprising: The cylindrical member 901 Is attached to the blade 113 of the drill 111, a setting step for setting the position of the cylindrical member 901 by closing the gap in the base 112 of the drill 111, and the blade 113 of the drill 111 corresponding to the machining dimension is exposed. As described above, the manufacturing dimension setting jig 902 includes a cutting step for cutting the cylindrical member 901 and a removing step for removing an end of the cut cylindrical member 901.

  In this way, with the cylindrical member 901 attached to the blade 113, the cylindrical member 901 is cut and manufactured so that the required exposure dimension (target value dimension Q2) of the blade 113 of the drill 111 is obtained. is doing. As described above, since the dimension setting by cutting is almost the final process, when the manufacturing of the processing dimension setting jig 902 is completed, the dimension setting can be kept close to the desired dimension setting. That is, when the dimension is set before the mounting (in the case of the processing dimension setting jig 101), deformation or distortion occurs due to the mounting process in the middle, and the processing dimension setting jig 101 is inserted into the blade 113 of the drill 111. There is a risk of dimensional deviation when attached to the. However, according to the manufacturing method of the processing dimension setting jig 902 of this embodiment, this dimensional deviation can be suppressed as much as possible.

  In addition, since the dimension setting by cutting is almost the final process in this way, when attaching to the drill 111 such that the drill base 112 has some unevenness, the contact is made so that the unevenness does not move. The cutting dimension can be set. Thereby, a desired dimension can be set even in the drill 111 in which the drill base 112 has some unevenness.

  Further, in the manufacturing method of the second embodiment, between the setting step and the cutting step, as shown in FIG. 11, the end portion 901B of the cylindrical member 901A is substantially attached to the tip of the blade 113 of the drill 111. It is a manufacturing method of the processing dimension setting jig | tool 902 further provided with the temporary cutting step cut | disconnected in alignment. For this reason, when the cylindrical member 901A is temporarily cut, the tip of the blade 113 can be seen, so that there is an advantage that it is easy to set dimensions for cutting unnecessary portions of the cylindrical member 901A.

  Next, a third embodiment will be described based on FIG.

  FIG. 13 is an explanatory view showing a processing dimension setting jig of the third embodiment.

  The sliding member 1301 is a disc-shaped perforated sheet. As the material of the sliding member 1301, any one of slippery ultra-high molecular weight polyethylene material, fluorine resin material, and silicon resin material can be used. The sliding member 1301 has a thickness that is thin enough to be called a sheet. The sliding member 1301 is attached to the end 902A of the processing dimension setting jig 902 and used. This end 902A is the side facing the workpiece, and is the tip side of the blade 113 of the drill 111.

  The workpieces 121 and 131 described in the first embodiment are made of a relatively hard material even if they are made of metal or synthetic resin, for example. For this reason, even if the end portion 902A of the processing dimension setting jig 902 is in contact with rotation, there is very little risk of damaging the opening periphery of the processing objects 121 and 131.

  However, in the processing object of a soft material or the processing object to which a member (for example, nameplate etc.) that is easily damaged is attached, when the end 902A of the processing dimension setting jig 902 hits, There is a risk of damaging the periphery of the opening.

  When there is a risk of damaging the workpiece, the sliding member 1301 is disposed and used at the end 902A of the machining dimension setting jig 902.

  By disposing the sliding member 1301, when the sliding member 1301 hits the workpiece, the surface smoothly slides. For this reason, if this sliding member 1301 is used, the object to be processed can be made difficult to be damaged.

  When using a relatively thick sheet among the sliding members 1301, it is necessary to set the dimension of the processing dimension setting jig 902 in consideration of this thickness.

  Next, a fourth embodiment will be described based on FIG.

  FIG. 14 is an explanatory view showing a processing dimension setting jig according to the fourth embodiment.

  The processing dimension setting jig 1401 includes a display unit 1402 on the drill base 112 side. The display unit 1402 displays the type of drill such as the outer diameter size and hardness of the drill. As a display mode, any one of a display unit 1402A by color, a display unit 1402B by characters and symbols, and a display unit 1402C by which an operator can enter the type of drill can be used. Further, the display unit 1402 may be displayed by direct printing of colors and characters, or may be displayed by pasting a printed label.

  In general, the drill is used while replacing the outer diameter and hardness of the blade and different types of blades. For this reason, a plurality of types of blades are often used.

  For example, there is a case where a machining operation is performed using a drill blade of the type A001, and then the blade of the drill is replaced with a blade of the type B002 and machining is performed with the type of blade of the type B002. Furthermore, a drill blade of the type A001 may be used again.

  In such a case, the drill blade of the type A001 intended for use can be easily searched with reference to the display unit 1402, so that the working efficiency can be improved. At this time, it is necessary to leave the processing dimension setting jig 1401 once attached to the blade 113 of the drill 111.

  Moreover, although the same A001 drill blade is used, the target value may change due to the change of the workpiece. When the target value increases (when the exposed dimension of the blade increases), the attached processing dimension setting jig is further cut and used so that the target target value is obtained. When the target value is small (when the exposed dimension of the blade is small), the current machining dimension setting jig is removed and a new machining dimension setting jig is attached for use. In this case, if the processing dimension setting jig 101 shown in the first embodiment is formed in advance with a predetermined dimension, it can be used immediately. However, in the case of the cylindrical member 901 as shown in the second embodiment that is not formed in a predetermined dimension, after manufacturing the processing dimension setting jig 902 by processing so that a necessary dimension portion remains, Can be used.
