Description

Technical Field

[0001] This utility model relates to the field of electric hammer technology, specifically a clutch gear assembly for an electric hammer clutch. Background Technology

[0002] In existing technologies, clutch gear assemblies used in electric hammers generally include a clutch gear body, a distance ring, and a clutch gear spring. In existing technology, when installing the clutch gear assembly, after the cylinder is inserted into the front cylinder, the distance ring must first be placed into the front cylinder, then the clutch gear spring into the distance ring, and finally the clutch gear body is inserted into the distance ring. During the insertion of the clutch gear body into the distance ring, the clutch gear body needs to press down on the clutch gear spring to maintain it in a compressed state. Since there is no fixing structure between the clutch gear body and the distance ring, manual maintenance is required; that is, the operator must continuously maintain pressure on the clutch gear body. Then, the clutch, clutch spring, large bevel gear, and other parts are installed on the cylinder. This installation method is extremely inconvenient, time-consuming, and labor-intensive, and may even require special tools to complete assembly or disassembly, increasing maintenance costs.

[0003] Therefore, this utility model proposes a technical solution to solve the problem of inconvenient, time-consuming and labor-intensive installation caused by the lack of a fixing structure between the clutch gear ring body and the distance ring. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a clutch gear ring assembly for electric hammer clutches, aiming to achieve a fixed connection between the clutch gear ring body and the clutch ring through a fixed structure, so that the operator does not need to maintain a constant pressure on the clutch gear ring body, thus facilitating the installation of the clutch gear ring assembly.

[0005] A clutch gear ring assembly for an electric hammer clutch includes a clutch gear ring body, a distance ring, and a clutch gear ring spring. An annular protrusion is integrally formed on the inner sidewall of the distance ring. The clutch gear ring body is inserted into the distance ring in a mating connection manner, with a gap maintained between it and the annular protrusion. The clutch gear ring spring is located within the gap and abuts against the annular protrusion and the clutch gear ring body. A fixing structure for fixing the clutch gear ring body within the distance ring is provided between the clutch gear ring body and the distance ring.

[0006] By adopting the above technical solution, the clutch gear spring is first placed inside the distance ring, where it is held in place by the annular protrusion. Next, the clutch gear body is inserted into the distance ring in a mating connection manner, and the clutch gear spring is pressed down. Then, the clutch gear body is fixed inside the distance ring using a fixing structure. At this point, the clutch gear body, distance ring, and clutch gear spring form a single assembly. When installing the clutch gear assembly, after the cylinder is inserted into the front cylinder, the clutch gear assembly can be easily placed into the front cylinder. Then, the clutch, clutch spring, large bevel gear, and other parts are installed on the cylinder, and the front cylinder assembly is easily installed into the gearbox. This utility model, through its fixing structure, eliminates the need for continuous pressure on the clutch gear body, making the installation of the clutch gear assembly quick, convenient, and time-saving.

[0007] A further feature of this invention is that a plurality of positioning grooves are provided on the inner sidewall of the clutch ring, and a positioning block for inserting into the positioning grooves is integrally formed on the outer sidewall of the clutch gear ring body.

[0008] By adopting the above technical solution, when the clutch gear ring body is inserted into the distance ring in a mating connection manner, the positioning block is aligned with the positioning groove, which can play a positioning role and prevent relative rotation between the clutch gear ring body and the distance ring.

[0009] A further feature of this invention is that the number of the fixing structures is at least two, and they are arranged in a ring array.

[0010] By adopting the above technical solution, the clutch gear body can be stably fixed within the distance ring.

[0011] Further features of this invention: The fixing structure includes a connecting hole, a notch, and a spring piece. The connecting hole is opened on the outer wall of the clutch ring and communicates with the interior of the clutch ring. The notch is opened on the clutch ring body near one end of the annular protrusion. The spring piece is integrally formed in the notch. A locking block is integrally formed on the outer wall of the spring piece, and the locking block is provided with an inclined surface.

[0012] By employing the above technical solution, when the positioning block is aligned with the positioning groove, and the clutch gear ring body is inserted into the distance ring in a mating connection manner, the inclined surface first presses against the end face of the distance ring. The end face of the distance ring forms a reaction force with the inclined surface. This reaction force can be decomposed into an inward force, which is transmitted to the spring plate through the locking block. Under the action of this force, the spring plate bends inward and generates a rebound force. After the spring plate bends, the clutch gear ring body can be inserted into the distance ring. When the clutch gear ring body is fully inserted into the distance ring and the positioning block is fully inserted into the positioning groove, the clutch gear ring body can no longer be inserted into the distance ring. At this time, the connecting hole corresponds to the locking block. Under the action of the rebound force of the spring plate, the spring plate resets, driving the locking block to reset, and the locking block inserts into the connecting hole, thereby fixing the clutch gear ring body in the distance ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] A clutch gear assembly for a hammer drill clutch, such as Figures 1-3 As shown, it includes a clutch gear ring body 1, a distance ring 2, and a clutch gear ring spring 3.

[0021] An annular protrusion 4 is integrally formed on the left side of the inner wall of the spacer ring 2. Several positioning grooves 5 are provided on the right end of the inner wall of the spacer ring 2.

[0022] The clutch gear ring body 1 is inserted into the distance ring 2 in a mating connection manner, and a gap is maintained between it and the annular protrusion 4. A positioning block 6 for inserting into the positioning groove 5 is integrally formed on the outer side wall of the clutch gear ring body 1.

[0023] The clutch gear spring 3 is located within the gap and abuts between the annular protrusion 4 and the clutch gear body 1.

[0024] Two fixing structures arranged in a ring array (i.e., symmetrically arranged vertically in this embodiment) are provided between the clutch gear body 1 and the distance ring 2. The fixing structures are used to fix the clutch gear body 1 within the distance ring 2. Each fixing structure includes a connecting hole 7, a notch 8, and a spring piece 9. The connecting hole 7 is located on the outer wall of the distance ring 2 and communicates with the interior of the distance ring 2. The notch 8 is located on the clutch gear body 1 near one end of the annular protrusion 4. The spring piece 9 is integrally formed within the notch 8. A retaining block 10 is integrally formed on the outer wall of the spring piece 9. The retaining block 10 has an inclined surface 11.

[0025] Installation principle: First, insert the clutch gear spring 3 into the distance ring 2. The clutch gear spring 3 will be held in place by the annular protrusion 4. Next, insert the clutch gear body 1 into the distance ring 2 in a mating connection manner, and press the clutch gear spring 3. When inserting the clutch gear body 1 into the distance ring 2, the positioning block 6 should be aligned with the positioning groove 5. This serves both to position the clutch gear body 1 and prevent relative rotation between the clutch gear body 1 and the distance ring 2.

[0026] During the insertion of the clutch gear ring body 1 into the distance ring 2, the inclined surface 11 first presses against the end face of the distance ring 2. The end face of the distance ring 2 forms a reaction force against the inclined surface 11. This reaction force can be decomposed into an inward force, which is transmitted to the spring 9 via the locking block 10. Under the action of this force, the spring 9 bends inward and forms a rebound force. After the spring 9 bends, the clutch gear ring body 1 can be inserted into the distance ring 2. When the clutch gear ring body 1 is fully inserted into the distance ring 2 and the positioning block 6 is fully inserted into the positioning groove 5, the clutch gear ring body 1 can no longer be inserted into the distance ring 2. At this time, the connecting hole 7 corresponds to the locking block 10. Under the action of the rebound force of the spring 9, the spring 9 resets, driving the locking block 10 to reset. The locking block 10 is inserted into the connecting hole 7, thereby fixing the clutch gear ring body 1 in the distance ring 2.

[0027] At this point, the clutch gear ring body 1, the clutch ring 2, and the clutch gear ring spring 3 can form a single assembly. When installing the clutch gear ring assembly, after the cylinder is inserted into the front cylinder, the clutch gear ring assembly can be easily placed into the front cylinder. Then, the clutch, clutch spring, large bevel gear, and other parts are installed on the cylinder, and the front cylinder assembly is easily installed into the gearbox.

[0028] With the fixed structure, the present invention eliminates the need for workers to maintain constant pressure on the clutch gear body 1, making the installation of the clutch gear assembly quick, convenient, time-saving, and labor-saving.
