Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 5This utility model provides a technical solution: a heat-shrinkable tool holder positioning clamp, including a length extension control mechanism 1. The length extension control mechanism 1 includes a bracket 101, an adjustment groove 102 is provided on the bracket 101, a tool tray 103 is slidably connected in the adjustment groove 102, a tool extension hole 104 is provided on the inner wall of the top of the adjustment groove 102, the tool tray 103 is connected to a lifting mechanism, and a tool clamping part 2 is detachably installed on the top of the bracket 101 through a connecting structure. The tool clamping part 2 includes a long handle 201 and a short handle 202. Several sets of corresponding semi-circular tool clamping grooves 203 with different inner diameters are provided on the opposite side surface of the long handle 201 and the short handle 202. The long handle 201 and the short handle 202 are detachably connected by fasteners.

[0024] Please see Figures 3 to 5 The connection structure includes a connecting groove 105, in which a connecting slide bar 207 is slidably connected. The connecting slide bar 207 is integrally disposed on the bottom surface of the short handle 202. Corresponding alignment prompt structures are provided on the connecting slide bar 207 and the connecting groove 105.

[0025] The connecting groove 105 is located at the top of the bracket 101, and the connecting slide 207 is integrally set at the bottom of the short handle 202. The two are slidably connected to realize the detachable installation of the tool clamping part 2 and the length extension control mechanism 1. The centering prompt structure set on the connecting slide 207 and the connecting groove 105 is used to ensure that the tool clamping groove 203 and the tool extension hole 104 are coaxially aligned. The physical cooperation prompts the user whether the current position is correct, avoiding the tool tilting installation due to misalignment, which would affect the accuracy of the extension length.

[0026] Furthermore, the centering prompt structure includes a centering positioning slot 106 formed on the inner wall of the bottom of the connecting slide 105 and a plurality of positioning protrusions 208 formed on the bottom surface of the connecting slide 207. The centering positioning slot 106 is located on the perpendicular line between the center of the tool extension hole 104 and the extension direction of the connecting slide 105. Each positioning protrusion 208 corresponds one-to-one with the plurality of tool clamping slots 203 formed on the short shank 202, and each positioning protrusion 208 is located on the perpendicular line between the center of the corresponding tool clamping slot 203 and the extension direction of the connecting slide 207.

[0027] The centering positioning slot 106 is formed on the bottom inner wall of the connecting slide 105. Its position is on the perpendicular line between the center of the tool extension hole 104 and the extension direction of the connecting slide 105, ensuring that the slot is aligned with the center of the tool extension hole. The number of positioning protrusions 208 on the bottom of the connecting slide 207 corresponds one-to-one with the number of tool clamping slots 203 on the short shank 202. Each positioning protrusion 208 is located on the perpendicular line between the center of the corresponding tool clamping slot 203 and the extension direction of the connecting slide 207. When the positioning protrusion 208 is engaged in the centering positioning slot 106, the corresponding tool clamping slot 203 is coaxial with the tool extension hole 104. This provides a tactile or visual prompt to the user and also serves as a limit to prevent misalignment between the clamping slot and the extension hole during adjustment, thus ensuring the tool installation accuracy.

[0028] Furthermore, a scale mark 107 is provided on one side surface of the bracket 101, and a corresponding indicator arrow structure 108 is provided on one side surface of the tool tray 103.

[0029] The scale mark 107 cooperates with the indicator arrow structure 108 on one side of the tool tray 103 to accurately display the tool extension length. The scale mark 107 is in millimeters and subdivided to 0.01mm. The indicator arrow structure 108 moves with the tool tray 103. By observing the scale value indicated by the arrow, the user can accurately adjust the tool extension length to ensure that the tool mounting accuracy meets the requirements of high-precision machining and avoid errors caused by manual estimation.

[0030] Furthermore, the lifting mechanism includes mounting grooves 109 formed at the bottom of the inner walls on both sides of the adjusting slide 102. Adjusting knobs 110 are rotatably mounted in the mounting grooves 109 on both sides. A threaded hole is formed through the middle of the adjusting knob 110. A screw 111 is threadedly connected to the threaded hole. The top end of the screw 111 is rotatably connected to the bottom surface of the tool tray 103. A screw extension hole 113 is formed through the inner wall at the bottom of the adjusting slide 102. An overhead support foot is provided at the bottom of the bracket 101. The bottom end of the screw 111 extends to the bottom of the bracket 101 through the screw extension hole 113.

[0031] Mounting slots 109 are formed at the bottom of the inner walls on both sides of the adjusting slide 102 for mounting adjusting knobs 110. The threaded hole in the middle of the adjusting knob 110 is threadedly connected to the screw 111. When the adjusting knob 110 is rotated, the screw 111 moves up and down, causing the tool tray 103 connected to the top to rise and fall in the adjusting slide 102. The overhead support at the bottom of the bracket 101 suspends the bottom of the device, allowing the bottom end of the screw 111 to extend through the screw extension hole 113, making it easy for the user to operate the adjusting knob 110, thus achieving smooth raising and lowering of the tool tray 103 and ensuring the accuracy and stability of length adjustment.

[0032] Furthermore, a tapered abutment groove 112 is provided on the top surface of the tool tray 103.

[0033] The tapered abutment groove 112 is used to abut the bottom end of the tool shank. The tapered structure can automatically position the tool, ensuring that the tool axis coincides with the axis of the tool extension hole 104, preventing the tool from tilting or shifting on the tray, while increasing the contact area between the tool and the tray, improving support stability, and avoiding tool shaking during adjustment that affects the length adjustment accuracy.

[0034] Furthermore, an annular slide bar 115 is integrally provided on the bottom surface of the adjustment knob 110, and the annular slide bar 115 is slidably connected to two arc-shaped slide grooves 114, which are respectively opened on the bottom inner wall of the corresponding mounting groove 109.

[0035] The annular slide bar 115 at the bottom of the adjusting knob 110 is slidably connected to the arc-shaped slide groove 114 at the bottom of the mounting groove 109. The annular slide bar 115 is coaxially set at the bottom of the adjusting knob 110 and can rotate freely in the arc-shaped slide groove 114, which restricts the axial movement of the adjusting knob 110 and ensures its rotational stability. This prevents the knob from shaking during adjustment, which would cause uneven force on the screw 111 and affect the stability and accuracy of the lifting and lowering of the tool tray 103, making the length adjustment process smoother.

[0036] Furthermore, both ends of the long handle 201 and the short handle 202 are provided with insertion holes 204, and two insertion holes 204 located at the same end are each fitted with a connecting bolt 205, and the end of each connecting bolt 205 is threaded with a fastening nut 206.

[0037] The insertion holes 204 at both ends of the long shank 201 and the short shank 202 are used to insert connecting bolts 205. The ends of the connecting bolts 205 are threadedly connected to the fastening nuts 206. By tightening the fastening nuts 206, the long shank 201 and the short shank 202 can be clamped together, thereby fixing the tool shank in the tool clamping groove 203. The bolt connection structure can provide sufficient clamping force to ensure that the tool does not loosen during adjustment and installation.

[0038] Furthermore, a number of evenly distributed anti-slip grooves 209 are provided on both sides of one end of the long handle 201.

[0039] The anti-slip grooves 209 on both sides of one end of the long handle 201 are used to increase the friction when holding the hand, to prevent the operator's hand from slipping when picking up or putting down the tool clamping part 2 or inserting the tool into the heat shrink handle, and to improve the safety of operation. Especially when the temperature of the tool handle is high after heating, the anti-slip grooves 209 can ensure that the operator holds the tool stably and avoid the tool installation position deviation or equipment damage caused by slipping.

[0040] Working principle: The precise adjustment of the tool extension length is achieved through the cooperation of the length extension control mechanism 1 and the tool clamping part 2. First, the position of the tool clamping part 2 on the length extension control mechanism 1 is adjusted according to the tool diameter. By utilizing the sliding cooperation between the connecting slide 207 and the connecting slide groove 105, the circular shape formed by a set of corresponding tool clamping slots 203 on the long shank 201 and the short shank 202 is aligned with the tool extension hole 104 through the centering indicator structure. After loosening the fastening nut 206, the tool is inserted into the tool clamping slot 203 and the tool extension hole 104, so that the tool shank abuts against the conical abutment groove 112 of the tool tray 103. At this time, by rotating the adjustment knob 110, the screw 111 is rotated, causing the tool tray 103 to slide up and down in the adjustment groove 102. When the tool moves with the tray, the displacement of the tray is judged by the relative position of the scale mark 107 and the indicator arrow structure 108. When adjusting, the influence of the depth d of the conical abutment groove 112 and the thickness t of the long shank 201 and the short shank 202 on the protrusion length needs to be considered. The actual protrusion length is the sum of the scale value and d and t. After the adjustment is completed, the fastening nut 206 is locked to clamp the tool in the tool clamping groove 203. Then the tool clamping part 2 is removed and the tool is inserted into the heated tool holder. The installation is completed by using the heat shrink principle.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
