Description

Technical Field

[0001] This application relates to the technical field of coil frame processing, and in particular to a fixture for drilling holes in the end face of a coil frame. Background Technology

[0002] like Figure 1 As shown, the coil frame is a ring structure with an inverted L-shaped longitudinal section. The coil frame has a round hole on its side. Now, it is necessary to drill a hole in the upper end face of the coil frame. In the existing technology, factories usually use vertically lifting drill bits. Therefore, before processing the coil frame, the processing position needs to be marked on the upper end face. Then, the workers align the drill bit with the marked position to process.

[0003] In actual processing, since the number of coil frames that need to be processed is large, if each one requires the worker to align the drill bit with the marked position, after working for a long time, it is inevitable that the drill bit will not be aligned with the marked position, resulting in errors in the holes drilled on the coil frame, causing the coil frame to be scrapped and increasing factory costs. Utility Model Content

[0004] This application provides a fixture for drilling holes in the end face of a coil frame to solve the problem of requiring manual alignment of the machining position in related technologies.

[0005] In a first aspect, a fixture for drilling holes in the end face of a coil frame is provided, comprising:

[0006] Fixture;

[0007] The placement frame is rotatably connected to the fixed frame. The placement frame is provided with a limiting structure, and there is a placement space between the limiting structure and the placement frame for fixing the coil frame.

[0008] Several angle limiting components are arranged circumferentially around the edge of the placement frame. The angle limiting components include a groove and an insert. The groove is set on the fixed frame, and the insert is slidably connected to the placement frame. The insert can be inserted into the groove.

[0009] In some embodiments, the angle limiting element also includes a spring;

[0010] The spring is connected to the insert block and the mounting bracket at both ends. The side of the insert block facing the groove is arc-shaped, and the groove is also arc-shaped.

[0011] In some embodiments, the limiting structure includes a limiting ring and a limiting block;

[0012] The limiting ring and the placement frame form a space for limiting the placement of the coil frame. The limiting block is slidably connected to the placement frame and can be used to insert into the round hole of the coil frame.

[0013] In some embodiments, the limiting structure also includes a threaded sleeve, a threaded block, and a connecting rod;

[0014] The threaded sleeve is connected to the placement frame, and the two ends of the connecting rod are respectively connected to the threaded block and the limiting block. The threaded block is set inside the threaded sleeve, and the threaded block and the threaded sleeve are threadedly connected.

[0015] In some embodiments, the threaded block and the limiting block are rotatably connected, and the threaded sleeve is provided with a protrusion that is slidably connected to the connecting rod.

[0016] In some embodiments, the limiting structure also includes a rotating rod;

[0017] One end of the rotating rod is connected to the threaded block.

[0018] In some embodiments, the limiting structure further includes a drive rod;

[0019] The rotating rod is fitted inside the driving rod, which is rotatably connected to the placement frame. The rotating rod has a boss that is slidably connected to the driving rod.

[0020] This application provides a fixture for drilling holes in the end face of a coil frame. Since this application fixes the coil frame on a placement frame and the placement frame rotates on the fixed frame, when the position of the coil frame to be processed in the placement frame rotates to below the drill bit, that is, when the insert block is above the groove, the insert block is inserted into the groove, which makes it convenient for the operator to process the position of the coil frame to be processed. Therefore, this application determines whether the position of the coil frame to be processed has rotated to below the drill bit by the position of the insert block and the slot, thereby avoiding manual judgment of whether the processing position is aligned.

DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] The coil holder end face drilling clamp provided in the embodiments of the present application can solve the problem of manual alignment of the machining position in the related art.

[0030] Please refer to Figures 1 to 5 A coil holder end face drilling clamp, comprising:

[0031] The fixed frame 1;

[0032] The placing frame 2 is rotationally connected to the fixed frame 1, and the placing frame 2 is provided with the limiting structure 3, and there is a placing space for fixing the coil holder between the limiting structure 3 and the placing frame 2;

[0033] The angle limiting pieces 4 are circumferentially arranged around the edge of the placing frame 2, and the angle limiting piece 4 comprises the groove 41 and the plug 42, the groove 41 is arranged on the fixed frame 1, and the plug 42 is slidingly connected to the placing frame 2, and the plug 42 can be inserted into the groove 41;

[0034] In the prior art, a drilling machine is usually used to drill a workpiece, and the drill bit can only vertically ascend and descend on the drilling machine, the number of the coil holder upper end faces to be drilled is four, and the four to-be-machined positions are circumferentially distributed on the coil holder upper end face;

[0035] In the application, the fixed frame 1 is fixedly installed on the drilling machine, the fixed frame 1 is a column structure, the placing frame 2 is arranged on the fixed frame 1, and the coil frame is fixed in the middle of the placing frame 2 through the limiting structure 3. In the specific operation, the placing frame 2 is rotated on the fixed frame 1, so that the coil frame rotates around the center of the coil frame, the angle limiting piece 4 is arranged between the placing frame 2 and the fixed frame 1, when the plug block 42 is rotated to above the recess 41 under the driving of the placing frame 2, the plug block 42 is inserted into the recess 41, at this time, the position to be machined on the upper end surface of the coil frame is located below the drill bit, the worker knows that the drill bit can be controlled to descend to drill at this time, and the above operation process is repeatedly repeated, so that the four positions to be machined at different positions are rotated to below the drill bit for machining. In this process, it is not necessary to manually judge whether the drill bit is above the machining position of the coil frame, so as to avoid the possibility of manual judgment error.

[0036] It should be pointed out that the position of the fixed frame 1 on the drilling machine in the application needs to meet that at least one position to be machined is below the drill bit, so when the position of the fixed frame 1 is selected, only one position to be machined needs to be aligned below the drill bit.

[0037] The angle limiting piece 4 further comprises a spring 43;

[0038] The spring 43 is connected to the plug block 42 and the placing frame 2 at two ends respectively, one side of the plug block 42 facing the recess 41 is arc-shaped, and the recess 41 is arc-shaped;

[0039] In the application, in order to meet the machining of the four positions to be machined of the coil frame, the number of the angle limiting pieces 4 is four, and the four angle limiting pieces 4 are distributed in the circumferential direction around the edge of the placing frame 2, so that when the coil frame is fixed on the placing frame 2, the positions of the four angle limiting pieces 4 correspond to the four positions to be machined of the coil frame;

[0040] Four elastic grooves are arranged at the bottom of the placing frame 2, the four elastic grooves correspond to the four angle limiting pieces 4, the plug block 42 is slidingly connected in the elastic groove, and the spring 43 is arranged between the elastic groove and the plug block. The spring 43 will continuously provide the plug block 42 with a force to pop out of the elastic groove. When the placing frame 2 rotates on the fixed frame 1, the arc-shaped side of the plug block 42 will abut against the fixed frame 1, at this time, the plug block 42 is retracted in the elastic groove. When the plug block 42 moves to above the recess 41, the plug block 42 will be inserted into the recess 41 under the action of the spring 43, at this time, it indicates that the position to be machined on the coil frame is below the drill bit;

[0041] In the embodiment, since the groove 41 and the side of the plug 42 facing the groove 41 are arc-shaped, and the plug 42 can completely fit the groove 41, after the plug 42 is inserted into the groove 41, the holder 2 continues to rotate, and the holder 2 drives the plug 42 to move. In this process, the plug 42 is pressed inward by the groove 41 and shrinks until the plug 42 moves out of the groove 41 and is retracted into the elastic groove. At the same time, when the plug 42 is in the groove 41, the plug 42 is gradually completely fitted with the groove 41 under the action of the spring 43. When the plug 42 is completely fitted with the groove 41, the position to be processed on the coil holder is located below the drill bit. Therefore, in actual operation, the worker will feel a clear jerk when rotating the holder 2. The jerk is caused by the plug 42 when it is separated from the groove 41. When the worker feels the jerk, he gives up controlling the holder 2. Under the action of the spring 43, the plug 42 will gradually fit with the groove 41.

[0042] The limiting structure 3 includes a limiting ring 31 and a limiting block 32.

[0043] The limiting ring 31 and the holder 2 form a placement space for limiting the coil holder. The limiting block 32 is slidingly connected to the holder 2 and can be inserted into the circular hole of the coil holder.

[0044] In the embodiment, the holder 2 is a hollow cylindrical structure with one side open. The coil holder can be placed into the holder 2 from the opening of the holder 2. The limiting ring 31 is arranged on the surface of the holder 2 opposite to the opening. The size of the limiting ring 31 matches that of the coil holder. When the coil holder is placed into the holder 2 from the opening and the contact surface of the coil holder is located in the limiting ring 31, the position of the coil holder in the holder 2 is fixed.

[0045] The limiting block 32 moves towards or away from the center of the holder 2 on the holder 2. In order to facilitate the configuration of a driving device for the limiting block 32, in a preferred embodiment, the limiting block 32 moves on the same horizontal plane. In a preferred embodiment of the holder 2, the holder 2 is located at the center of the holder 2. When the coil holder is fixed at the center of the holder 2, the coil holder is rotated to adjust the position of the circular hole of the coil holder so that the opening direction of the circular hole faces the limiting block 32, thereby facilitating the insertion of the limiting block 32 into the circular hole. When the coil holder is fixed at the center of the holder 2 and the limiting block 32 is inserted into the circular hole, the coil holder is fixed at the center of the holder 2, that is, the coil holder rotates with the holder 2.

[0046] It should be noted that the position of the limiting block 32 needs to be ensured. After the coil holder is fixed, the position to be processed on the coil holder matches the position of the angle limiting piece 4, that is, when the worker rotates the holder 2 and the plug 42 is inserted into the groove 41, the position to be processed is located directly below the drill bit.

[0047] The limiting structure 3 further comprises a threaded sleeve 33, a threaded block 34 and a connecting rod 35;

[0048] The threaded sleeve 33 is connected with the placing rack 2, the connecting rod 35 has two ends respectively connected with the threaded block 34 and the limiting block 32, the threaded block 34 is arranged in the threaded sleeve 33, and the threaded block 34 is threadedly connected with the threaded sleeve 33;

[0049] The threaded block 34 is rotationally connected with the limiting block 32, the threaded sleeve 33 is provided with a protruding block 5, and the protruding block 5 is slidingly connected with the connecting rod 35;

[0050] The threaded sleeve 33 is a hollow cylinder with a threaded inner surface, the threaded block 34 is rotationally connected with one end of the connecting rod 35, the side surface of the threaded block 34 is provided with threads, and the threaded block 34 is threadedly matched with the threaded sleeve 33, as shown in Figure 4 The connecting rod 35 is provided with a limiting groove along the length direction of the connecting rod 35, the protruding block 5 slides in the limiting groove, and thus the connecting rod 35 can only slide in the threaded sleeve 33 and cannot rotate, so that when the threaded block 34 rotates in the threaded sleeve 33, the threaded block 34 drives the connecting rod 35 and the limiting block 32 to move.

[0051] The limiting structure 3 further comprises a rotating rod 36;

[0052] One end of the rotating rod 36 is connected with the threaded block 34;

[0053] The limiting structure 3 further comprises a driving rod 37;

[0054] The rotating rod 36 is sleeved in the driving rod 37, the driving rod 37 is rotationally connected with the placing rack 2, the rotating rod 36 is provided with a protruding table 6, and the protruding table 6 is slidingly connected with the driving rod 37;

[0055] The threaded block 34 is arranged in the threaded sleeve 33, in order to facilitate the staff to control the rotation of the threaded block, the rotating rod 36 is fixed on the threaded block 34, if the threaded block 34 is directly controlled through the rotating rod 36, since the rotating rod 36 will move with the threaded block 34, the rotating rod 36 will occupy more space, therefore the driving rod 37 is rotationally connected with the placing rack 2, the rotating rod 36 is provided with a slot matching with the protruding table 6, the protruding table 6 on the driving rod 37 is clamped in the slot of the rotating rod 36, the driving rod 37 drives the rotating rod 36 to move by rotating, in the movement process of the rotating rod 36 following the threaded block 34, the protruding table 6 moves in the slot, as shown in Figure 4 The staff can control the limiting block 32 to be inserted into or pulled out of the circular hole by rotating the driving rod 37 on the side surface of the placing rack 2.

[0056] The working principle of the application is as follows:

[0057] Before using, the position of the application needs to be adjusted according to the position of the drill bit, after fixing the position of the fixing frame 1, the coil frame is placed in the limiting ring 31, and then the limiting block 32 is inserted into the circular hole through the control of the driving rod 37, so as to fix the coil frame on the placing frame 2, the worker rotates the placing frame 2, so that the position to be processed on the coil frame is close to the position below the drill bit, when the worker feels obvious resistance, the control of the placing frame 2 can be released, at this time, the insertion block 42 will gradually fit with the groove 41, when the insertion block 42 fits with the groove 41, the position to be processed is located directly below the drill bit, at this time, the worker can process the position to be processed using the drill bit;

[0058] It should be pointed out that, in the design of the application, the position to be processed of the coil frame needs to match the position of the angle limiting piece 4, so the above method can be used every time the coil frame is rotated to adjust the position to be processed.
